The memory layer for AI agents: knowledge graph, vectors and graph RAG on one engine, written from scratch. Run it on your own hardware. This file is for coding agents: how to install a node, how to connect a coding agent, the memory tools an agent calls over MCP or HTTP, the same calls in each client, what Semurg publishes, and the rules an app built on a node follows. Every command, tool, route and client call named here is read from the source, checked against it before this file is published, and the commands are run against each published release.

Install a node
Before you install: Semurg runs on Intel and AMD x86_64 processors with AVX2 or newer, with 2 CPU threads and 4 GB of memory or more: on Ubuntu 24.04 with the installer, and on any other x86_64 Linux in Docker (the installer stops on another system and prints the docker run line that works there). There is no Mac, Windows or ARM build yet (they are coming, built from the same release); from a Mac or Windows machine, run the node on a Linux machine you can reach. WSL2 and Docker Desktop on Windows are being tested. The installer needs root.
One command, on a Linux machine you control. The first line shows the script without running it.
The installer ends with a SUCCESS banner that says where the node's API token is stored and the one command that reads it; the token itself is never printed, so it stays out of terminal logs and agent transcripts. The data directory must sit on a local ext4 or xfs filesystem; the installer checks this and stops if it does not. One node needs no licence key.
Put the token in your shell, then prove the gate is on (401 without the token, 200 with it):
Claude Code: one user-scope entry, written by Claude Code's own command. Run it in the shell that starts Claude Code; the entry holds only a reference to the variable, never the token itself. The address is the one a fresh node serves; behind your own TLS proxy use its https address.
export SEMURG_API_TOKEN=<the API token stored on your node>
claude mcp add-json --scope user semurg '{"type":"http","url":"http://127.0.0.1:4000/v1/mcp","headers":{"Authorization":"Bearer ${SEMURG_API_TOKEN}","X-Semurg-Scope":"default"}}'
# Claude Code reads the token from the SEMURG_API_TOKEN environment variable when it starts
Connected on release r11.130.20261026.cf29851: Claude Code's own client listed every memory tool that release served.
Claude Desktop: it runs on macOS and Windows and Semurg runs on Linux x86_64, so the node is reached at 127.0.0.1:4000 one of two ways: on a Windows machine, run the node on the same machine under WSL2 (Ubuntu 24.04), which is being tested, as is Docker Desktop on Windows; otherwise run it on a Linux machine and forward its port to the desktop with ssh -N -L 4000:127.0.0.1:4000 you@your-node, so the token never crosses the network over plain HTTP. A remote node over HTTPS with sign-in (OAuth) is not covered here yet. Claude Desktop starts only local (stdio) MCP servers, so the mcp-remote bridge, run by npx (it needs Node.js), carries it to the node's streamable HTTP door. Put this in claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/; Windows: %APPDATA%\Claude), put your token in place of , and restart Claude Desktop. The file then holds the token: keep it private.
Results pending. Any other MCP client: streamable HTTP at POST /v1/mcp on your node, the header Authorization: Bearer , and an optional X-Semurg-Scope header. Each agent's own configuration: https://one.semurg.io/agents
Agent memory over MCP
Endpoint: POST /v1/mcp on your node. It speaks streamable HTTP and takes the node's API token as a bearer token. An optional X-Semurg-Scope header sets the default scope for the connection.
Every tool except comms_bind_address, comms_send, comms_inbox, comms_thread and comms_read takes scope: Namespace. Agents on the same node using the same scope share these facts; another scope is private. Optional when the connection sets the X-Semurg-Scope header.
memory_status (read-only)
Report whether shared memory is on for this node and which of YOUR scopes hold facts. Pass scope to also get that scope's ontology summary: how many entity types and relation types it holds, its biggest classes (up to 50) with their member count (members_bound says "exact": the live members, measured to drop by one with every forget, also over 64 members) on their members, the relation types it already uses (reuse them spelled EXACTLY as listed in spellings), and the name-merge mode. Read-only. Call it first when another memory call fails.
Parameters:
user_id (string): Optional END USER inside your key (one app, many end users): every scope you name is then that end user's own, and two end users never meet. App-level separation, as mem0's user_id; a per-user token stays the security boundary. When the connection sets the X-Semurg-User header, that header IS the end user and a different user_id is refused. No ':', at most 256 bytes.
memory_remember (writes)
Store memory for agents. YOU ARE THE EXTRACTOR: whenever you store text (content or messages), send the entities and relations you found in it as facts in the SAME call. They are stored at once, and you extract better and faster than this node's local model, which reads text sent WITHOUT facts only in the background and slowly on a CPU (or not at all when none is installed). content: raw text (a note, a document), stored NOW: it is cut into passages of about 100-200 words at sentence ends, and each passage is linked to the entities it names that are already stored or that you send beside it as facts; the reply says extraction (agent_facts when you sent facts, known_names_only when not), how many passages no entity reaches (unlinked_passages) and meaning: queued when this node has an embedding model (the passages' vectors are written right behind the reply; memory_status says when), not_armed when it has none (the passages are embedded when one is installed). Without facts, the node's installed extraction model reads the stored text AFTER the reply and adds its entities, types and relations, each relation cited to the passage it was found in: model_extraction says pending (waiting on disk), done (already extracted), failed (a passage failed 3 attempts, named), other_model (extracted by another model), not_installed, not_serving or could_not_judge, by name; with facts no model runs. messages: a conversation [{role, content}], stored as one text, one line per turn, never a passage across two turns; otherwise exactly like content. facts: entities [{name, type}] and relations [{source, target, type}] that you extract yourself, for example type WORKS_AT; types are classes, matched letter case aside. passages: text to find again, [{text, mentions, key?}], stored NOW with no model: mentions names the entities the text is about (each is stored under the name as sent, and must appear in the text, letter case aside, or the passage is refused by name), and memory_context returns the passage WHOLE when it reaches one of them. content and passages cannot ride in one call. date (ISO 8601, for example 2026-10-01) is when this was said: it is kept with the call's source and returned with what it sourced. Storing the same thing again with the same date changes nothing (it answers already). Per call: at most 1000 entities and 5000 relations, 1048576 bytes of content, 1000 passages holding 1048576 bytes of text and 1000 mentions in all, each passage at most 65536 bytes; every name, mention and key at most 1024 bytes. source is an optional provenance label returned with the fact when it is recalled. Before you invent a type or a relation, call memory_status with your scope and reuse a class from ontology.top_classes and a relation from ontology.relations, spelled EXACTLY as listed in its spellings (a different spelling is a different relation, and the same fact stored twice). List both ends of every relation in entities in each remember call, including entities you stored earlier.
Parameters:
content (string): Raw text to remember, stored now and cut into sentence-bounded passages. Send the entities and relations you found in it as facts in the same call.
date (string): When this was said or true, ISO 8601 (2026-10-01 or 2026-10-01T09:30:00Z). Optional.
facts (object): Entities and the relations between them that YOU extracted from what you are storing: stored at once, no model runs.
messages (array): A conversation to remember as one text, one line per turn. Not beside content or passages.
passages (array): Text to find again later, stored now. Each passage names the entities it is about.
source (string): Optional source label (e.g. a file name). It is shown as the source name in each citation. Facts you send later under the same label (and without a "date") are attached to the document(s) you stored under it, so their citations quote that text; a label nothing was stored under, a call with a "date", a call that changes an attribute's current value, or a label that names more than 8 documents (a file stored as many passages) keeps its own source, named by the label (the reply's source_label_state says which: attached, new_source, dated_own_source, value_changed_own_source, many_documents_not_attached).
user_id (string): Optional END USER inside your key (one app, many end users): every scope you name is then that end user's own, and two end users never meet. App-level separation, as mem0's user_id; a per-user token stays the security boundary. When the connection sets the X-Semurg-User header, that header IS the end user and a different user_id is refused. No ':', at most 256 bytes.
memory_recall (read-only)
Recall what is stored about ONE entity: finds the entity named subject by its name, exact or a similar spelling or letter case ("paris" finds Paris, "Dan" finds Dana), or one whole word of a longer name ("Priya" finds Priya Raman; small English words such as "the" or "of" never match on their own), walks the graph from it and returns the connected facts in both directions (direction outbound or inbound), each with its citation (citation.source: kind document, or asserted for a fact an agent sent without text; the doc_id of the document it was read from; the name label it was stored under; ingested_at. citation.span: the sentence quoted from that document, start and end in Unicode code points of its full text, checked before it is served, or null with span_state saying why. citation.found_by: how it was found), its source_date when one was stored, and the seed that found it (seed: exact, name or type). Always current: a fact stored a moment ago is visible. A fact with direction derived (derived: true) was not stored: it follows from stored facts by its relation's meaning (symmetric: married_to, spouse_of, sibling_of; inverse: parent_of and child_of, owns and owned_by, employs and employed_by, manages and managed_by; transitive, up to 6 links: part_of, located_in, contained_in), and citation.found_by.reasoning names the rule and the stored facts it rests on, each one recallable on its own. The reply carries state: answered, nothing_stored (the name matched nothing: an explicit empty answer, never an invented one) or could_not_judge (a stage could not run, named in detail); seeding says what each stage did, and meaning reads not_armed until an embedding model is armed (searching by meaning is not available until then). source_id is the id of the node the item is made from (a passage: its chunk; a fact: the entity at its other end; an entity or type: itself), NOT of the document that sources it: that is citation.source.doc_id. Read-only. Ids (source_id, seed_id, citation.source.doc_id) are decimal STRINGS of a 64-bit unsigned integer: send them back unchanged and never convert them to a number (a JavaScript Number cannot hold one).
Parameters:
as_of (string): Read the memory as it was KNOWN at this instant (ISO 8601 date or date-time; a bare date is the end of that day UTC): a fact stored after it is not visible. Leave it out for now.
attribute (object): Find entities BY an attribute's current value, instead of by name: {"key": "ndis_number", "value": "430000001"} (optionally "type"). Only this scope is searched, the end user's own when user_id is set. Send it instead of subject.
compact (boolean): true: each item ONCE (text, kind, the fact's subject / relation / object, an entity's attributes as name: value, doc_id, source, date, score, seed) without the retrieval diagnostics (chunks, seeds, seeding, traversal): a fraction of the bytes. Leave it out for the full reply.
k (integer 1 to 1000): Most facts to return.
subject (string): The entity name to recall from: exact, or a similar spelling or letter case.
user_id (string): Optional END USER inside your key (one app, many end users): every scope you name is then that end user's own, and two end users never meet. App-level separation, as mem0's user_id; a per-user token stays the security boundary. When the connection sets the X-Semurg-User header, that header IS the end user and a different user_id is refused. No ':', at most 256 bytes.
valid_at (string): Read what was TRUE at this instant (ISO 8601), whatever was known since. With as_of: as known at as_of, true at valid_at.
memory_relate (writes)
Add ONE typed edge between two entities in a scope, for example from Alice to Bob with type MENTORS. Entities that are new are created. Returns whether the edge is physically present.
Parameters:
from (string, required)
to (string, required)
type (string, required): The relationship, for example WORKS_AT.
attributes (object): Typed attributes of THIS relationship, stored on it (role, frequency, valid_from / valid_to as ISO dates), by the same rules as an entity's attributes: {"role": "guardian_nominee", "valid_from": "2026-03-01"}.
replaces (boolean): true: this relationship REPLACES the subject's other stored targets of the same type (works_at, owned_by, reports_to, lives_in): they end at this call's date (or now) and stay readable with valid_at / as_of before it; stating an old one again later brings it back. The reply's replaces lists what ended (ended), what came back (restored), a relationship older than a stored one (older_than_stored: it is kept in history, ended where the newer one starts) and any subject with too many links to read whole (unread, state could_not_judge). Leave it out for a relationship that adds to the others (knows, visited).
user_id (string): Optional END USER inside your key (one app, many end users): every scope you name is then that end user's own, and two end users never meet. App-level separation, as mem0's user_id; a per-user token stays the security boundary. When the connection sets the X-Semurg-User header, that header IS the end user and a different user_id is refused. No ':', at most 256 bytes.
memory_forget (writes)
Forget something in a scope, ONE thing per call (send exactly one of subject, fact, passage, source, all, attribute). subject: an entity by its exact name: the entity, its place in the scope, its type memberships, every fact with it at either end AND every stored passage that names it are deleted, so recall, context, type lookups and passage search no longer return them; the reply counts passages_hidden and names documents_retained, the stored documents whose other text stays, and passages_retained (with passages_retained_why): how many live passages still contain a word of the name but were never linked to it; those stay until forgotten by the passage or source form. fact: {from, to, type}: just that one fact; both entities stay. passage: the doc_id that the remember verb returned: that stored document whole (its chunks, envelope and catalogue entries); the facts and entities it named stay. source: the label the documents were stored under (the source of a remember): every document filed under it, whole, as the passage form does one; the facts they asserted stay (facts_kept: true), and a source that was never stored is 404. all: send all: true with the scope to forget the WHOLE scope: every entity, fact, document and passage in it and the scope itself, in one call (the reply counts them and says what is kept); a scope that never existed is 404. An entity name is exact: with no match the call is refused with 404 and up to three close names to check ("Did you mean"); a close match is only suggested, never forgotten. Forgetting is idempotent: forgetting what is already forgotten answers the SAME 200 with already_forgotten: true and writes nothing; a thing that never existed is 404. A later remember that names it brings it back. Forgotten data is unreachable through every door of this node, but it is NOT physically erased today: the step that wipes forgotten data from the disk has not shipped, and until it does anyone with access to the node's disk or a backup can still read the bytes. reason is accepted and not stored.
Parameters:
all (boolean): Scope form: true forgets the WHOLE scope named by scope, every entity, fact, document and passage in it, and the scope itself. A scope that never existed is 404; the same call again answers already_forgotten.
attribute (object): Attribute form: {"subject": "", "key": ""}: forgets that one attribute (every value of a multi key); the entity and its other attributes stay.
fact (object): Fact form: the one fact to forget, spelled as memory_relate took it. Both entities stay.
passage (string): Passage form: the doc_id the remember verb returned for the stored document, as its decimal STRING, exactly as the reply gave it (an id is a 64-bit integer: as a JSON number above 2^53 it has already lost digits in most clients).
reason (string)
source (string): Source form: the label the documents were stored under; every document filed under it is forgotten whole, except one another source also stored (the same text is stored once): that one stays under the other source and only this label is removed from it (documents_kept). The facts those documents asserted stay.
subject (string): Entity form: the exact entity name to forget (a close spelling is suggested in the 404, never forgotten).
user_id (string): Optional END USER inside your key (one app, many end users): every scope you name is then that end user's own, and two end users never meet. App-level separation, as mem0's user_id; a per-user token stays the security boundary. When the connection sets the X-Semurg-User header, that header IS the end user and a different user_id is refused. No ':', at most 256 bytes.
memory_context (read-only)
Retrieve what the memory holds that is relevant to a question or a few words, ranked, each item with its citation (GraphRAG over one scope; the citation names the document that sources the item and the sentence it quotes). Every word or phrase of query that names a stored entity (exact, a similar spelling or letter case, one whole word of a longer name such as "Priya" for Priya Raman, or the start of a word such as "Pri") or a stored type ("which companies") becomes a seed; small English words such as "the", "of", "is", "who", "tell", "me" or "about" never match on their own. The graph is walked hops steps out from the seeds, and the ranked facts and the passages that mention them come back with their text, citation (citation.source: kind document, or asserted for a fact an agent sent without text; the doc_id of the document it was read from; the name label it was stored under; ingested_at. citation.span: the sentence quoted from that document, start and end in Unicode code points of its full text, checked before it is served, or null with span_state saying why. citation.found_by: how it was found), source_date and the seed that found each. No model is called: YOU write the answer from what comes back and cite citation.source.doc_id (quote citation.span.text). When nothing matches, state is nothing_stored and items is empty (seeding says what each stage did); could_not_judge names the stage that could not run. A fact with direction derived (derived: true) was not stored: it follows from stored facts by its relation's meaning (symmetric: married_to, spouse_of, sibling_of; inverse: parent_of and child_of, owns and owned_by, employs and employed_by, manages and managed_by; transitive, up to 6 links: part_of, located_in, contained_in), and citation.found_by.reasoning names the rule and the stored facts it rests on, each one recallable on its own. meaning reads not_armed until an embedding model is armed: a paraphrase that shares no name with the question is not found until then. Once armed, the question is embedded and scored against this scope's passages beside the name and word sources (seeding.meaning says ran, with coverage incomplete while passages still wait for their vectors). Two limits, by name: entity names (labels) and the sentences of facts are not embedded, so a fact you stored without a passage is not found by meaning; and the meaning search is exact up to 10,000 passages per scope, above which it answers could_not_judge naming the count, never a partial list, until the per-scope index lands. A match by meaning ALONE must clear the embedding model's calibrated cosine floor: a subject nothing holds answers nothing_stored, never the nearest passage. A stored name that shares ONE ordinary word with a longer question can come back as if it answered it ("capital" in a question about France matches a stored "Capital One"): read the reply's grounding before relying on them: grounded means ONE cited item covers every content word of your question (words covered only across several items are related, reason covered_only_across_items); grounded_by_meaning means a cited passage found by MEANING answers a REWORDED question, one that names no stored entity exactly and no name the passage lacks (the words it does not share are listed as uncovered; a meaning hit about a thing the question names is related, because being about it is not stating the answer): read it, and answer from it when it does answer; related (with the uncovered words, and the stored names that matched as related), uncited, nothing_stored and could_not_judge mean the facts do NOT answer the question, so say so instead of answering from them. source_id is the id of the node the item is made from (a passage: its chunk; a fact: the entity at its other end; an entity or type: itself), NOT of the document that sources it: that is citation.source.doc_id. Read-only. Ids (source_id, seed_ids, citation.source.doc_id) are decimal STRINGS of a 64-bit unsigned integer: send them back unchanged and never convert them to a number (a JavaScript Number cannot hold one).
Parameters:
query (string, required): A question or a few words; the entity names and type words inside it are what is matched (exact, a close spelling or letter case, one whole word of a longer name, or the start of a word); small English words such as "the" or "of" are not matched on their own.
as_of (string): Read the memory as it was KNOWN at this instant (ISO 8601 date or date-time; a bare date is the end of that day UTC): a fact stored after it is not visible. Leave it out for now.
compact (boolean): true: each item ONCE (text, kind, the fact's subject / relation / object, an entity's attributes as name: value, doc_id, source, date, score, seed) without the retrieval diagnostics (chunks, seeds, seeding, traversal): a fraction of the bytes. Leave it out for the full reply.
hops (integer 0 to 3): How far to walk from the matched entities (default 2).
k (integer 1 to 100): Most facts to return (default 8).
user_id (string): Optional END USER inside your key (one app, many end users): every scope you name is then that end user's own, and two end users never meet. App-level separation, as mem0's user_id; a per-user token stays the security boundary. When the connection sets the X-Semurg-User header, that header IS the end user and a different user_id is refused. No ':', at most 256 bytes.
valid_at (string): Read what was TRUE at this instant (ISO 8601), whatever was known since. With as_of: as known at as_of, true at valid_at.
memory_document (writes)
Store a DOCUMENT (a PDF, a Word .docx, an HTML page or a UTF-8 text file) as memory in one call: its bytes land in this node's customs, its text is parsed (paragraphs, headings and list items in order; PDF paragraphs are rebuilt from the page layout, not one per line), stored exactly as the remember verb stores content, read back byte for byte, and only then is the file deleted from customs. The reply carries doc_id (the source id every later citation names, a decimal STRING), the parsed text (citation offsets index it) and blocks (each block's page, paragraph and byte span in the text) when the text is at most 16384 bytes (over that, text_bytes and block_count instead: the text is stored whole and found by recall and context), and customs.emptied. Send the file as content_base64 (standard base64), at most 5000000 bytes once decoded; name is the label stored with it (optional). The kind is read from the file's own first bytes, never from its name. A file that is not a document of those kinds is refused before anything is stored (415); a truncated or corrupt document is refused BY NAME (document_corrupt, 422) and nothing is stored; an encrypted or scanned PDF is document_not_readable (422).
Parameters:
content_base64 (string, required): The document's bytes, standard base64.
name (string): The document's name, stored as its provenance label (optional).
user_id (string): Optional END USER inside your key (one app, many end users): every scope you name is then that end user's own, and two end users never meet. App-level separation, as mem0's user_id; a per-user token stays the security boundary. When the connection sets the X-Semurg-User header, that header IS the end user and a different user_id is refused. No ':', at most 256 bytes.
memory_export (read-only)
Export EVERYTHING a scope holds, one page per call: send cursor from the previous reply's next until next is null. Each record is a JSON object (write one per line for a .jsonl file): entity (name, types, current attributes with valid_from), fact (subject, relation, object, both ends' types, the relationship's attributes, its sources with dates, and state current or ended with ended_at and replaced_by), document (each stored text ONCE, its live passages in order, with its date and source label; a forgotten passage is never exported), and an export header on the first page. memory_import takes these records back into any scope. Read-only. limit = catalogue entries walked per page (default 256, at most 1024).
Parameters:
cursor (string): The previous page's next, unchanged; leave it out for the first page.
limit (integer 1 to 1024): Catalogue entries walked in this page (default 256).
user_id (string): Optional END USER inside your key (one app, many end users): every scope you name is then that end user's own, and two end users never meet. App-level separation, as mem0's user_id; a per-user token stays the security boundary. When the connection sets the X-Semurg-User header, that header IS the end user and a different user_id is refused. No ':', at most 256 bytes.
memory_import (writes)
Store the records memory_export produced (any page, in any order; a page sent twice stores nothing twice) into a scope, through the same writes remember makes: documents as their text with date and source label, entities with their types and attributes, facts with their dated sources, and an ended fact ended again at its ended_at, so history reads as it did. The reply counts what was imported, names every record it skipped (skipped: index and why) and lists what an import does not reproduce (not_reproduced). At most 4096 records a call.
Parameters:
records (array, required): Records exactly as memory_export returned them.
user_id (string): Optional END USER inside your key (one app, many end users): every scope you name is then that end user's own, and two end users never meet. App-level separation, as mem0's user_id; a per-user token stays the security boundary. When the connection sets the X-Semurg-User header, that header IS the end user and a different user_id is refused. No ':', at most 256 bytes.
comms_bind_address (writes)
Bind an address name@<cluster domain> to YOU (your token's identity, or the end user you name with user_id), so humans and agents on this cluster can message you by name. Humans and agents bind through the identical call; kind says which you are (user, the default, or agent). Idempotent: binding the same address again answers bound: "already". Refused by name: address_invalid (ASCII letters, digits, ., -, _, + only, exactly one @), domain_not_ours (the cluster's domains are listed in the fix), address_taken (bound to someone else), kind_invalid. A write: it needs an API token.
kind (string): What the bound principal is: user (a human; the default) or agent.
user_id (string): Optional END USER inside your key (one app, many end users): the call is then that end user's. When the connection sets the X-Semurg-User header, that header IS the end user and a different user_id is refused.
comms_send (writes)
Send a message from YOU to one or more addresses on this cluster (humans or agents, name@<cluster domain>). The text is stored ONCE, as a memory passage of the CONVERSATION of its audience (you + the recipients); recipients read it in their inbox / thread, and every member can recall it. Answers the message id, the conversation id, the passage id and delivered_to. Refused by name: address_unknown (the detail names every unknown address; nothing is sent), recipients_too_many (above 4096), subject_too_long, body_too_large. A write: it needs an API token.
Parameters:
to (array, required): The recipients' addresses, 1 to 4096.
body (string, required): The message text, at most 16 MiB.
reply_to (string): Optional: the id of the message this replies to.
subject (string): Optional subject, at most 1024 bytes.
user_id (string): Optional END USER inside your key (one app, many end users): the call is then that end user's. When the connection sets the X-Semurg-User header, that header IS the end user and a different user_id is refused.
comms_inbox (read-only)
Your conversations, one page per call (oldest first; next resumes, "end" on the last page): per conversation its id, the member count, the last message time, a preview, the message count and YOUR unread count. degree = how many conversations you are in. Read-only; a caller with no conversations gets an empty page.
Parameters:
after (string): Resume a page: the next the previous page answered (omit for the first page).
limit (integer 1 to 4096): Page size, 1 to 4096 (default 50).
user_id (string): Optional END USER inside your key (one app, many end users): the call is then that end user's. When the connection sets the X-Semurg-User header, that header IS the end user and a different user_id is refused.
comms_thread (read-only)
The messages of one conversation you are a member of, one page per call (oldest first; next resumes), each with its id, sender, time, subject, body and passage id; reading a page advances your unread cursor. Refused by name: not_a_member, conversation_not_found, page_cursor_invalid.
Parameters:
conversation_id (string, required): The conversation id (a decimal string, as the inbox or a send answered it).
after (string): Resume a page: the next the previous page answered (omit for the first page).
limit (integer 1 to 4096): Page size, 1 to 4096 (default 50).
user_id (string): Optional END USER inside your key (one app, many end users): the call is then that end user's. When the connection sets the X-Semurg-User header, that header IS the end user and a different user_id is refused.
comms_read (read-only)
One message by id (sender, time, subject, body, passage id, its conversation), for a member of its conversation. Refused by name: message_not_found, not_a_member.
Parameters:
message_id (string, required): The message id (a decimal string).
user_id (string): Optional END USER inside your key (one app, many end users): the call is then that end user's. When the connection sets the X-Semurg-User header, that header IS the end user and a different user_id is refused.
The same verbs over HTTP
Each route takes a JSON body with the same fields as the tool of the same name, and the header Authorization: Bearer <token>.

POST /v1/memory/audit
Both examples ran against a fresh node on release r11.130.20261026.cf29851, and each answer was read back. They use http://127.0.0.1:4000, the address a fresh node serves; behind your own TLS proxy use its https address instead. Set SEMURG_API_TOKEN to your node's API token.
Eleven languages in one archive, https://one.semurg.io/dl/clients.tar.gz, with CONNECTING.md, the guide to pointing a client at your node. A client takes the base URL of your node and its token. The memory calls each client defines, in its own spelling:
Semurg publishes no package on npm, crates.io, NuGet, Hex, Maven Central, the Go module proxy, the Julia General registry and opam today. A package on these registries that claims to be Semurg's is not ours: do not install it.
Building an app on a node
There are two kinds of app. An EXTERNAL app, in any language and any web framework, keeps its data in a node through the node's public API (the memory routes, /v1/ingest, /v1/query and its operations, the MCP tools, or a client): the node is its store, and nothing below applies to it. Build this kind today. An IN-NODE app is an Elixir extension that runs inside the node on the capabilities the node ships with, which Semurg calls packs; it will be published through the Marketplace only when the composition check passes (the check exists today; the publish and install path for in-node apps is still being built). Each rule below is one the check enforces, for IN-NODE apps only:
An app brings no database of its own: the node is the store, and the app reaches it only through the node's public read and write API.
An app builds only on packs: never on another app or on the node's own internals, and no chain of apps and packs ever loops back on itself.
Across packs, an app uses only what a pack declares it exposes.
A web interface is Phoenix LiveView. A controller-only or JSON-only surface is refused.
Pages
https://one.semurg.io/: Semurg is the memory layer for AI agents and agent frameworks: one shared memory over MCP or plain HTTP that outlives the session, with a knowledge graph, vector search and graph RAG built in, bigger than RAM, on your own hardware. One engine, written from scratch, for ten data domains, measured in the open domain by domain. The first node is free, forever.
https://one.semurg.io/agents: A shared memory for AI agents: remember, recall, relate and forget facts and relationships through MCP or plain HTTP, in the same store that serves your graph, vector and retrieval work.
https://one.semurg.io/develop: Build vector and graph RAG on one engine: vectors and graph on one copy of your data, relationships written as you write the data, and no new query language to learn.
https://one.semurg.io/commands: Every command Semurg tells you or your coding agent to run, read from the source and run against each published release. This file, as a page.
https://one.semurg.io/blog: The Semurg blog: announcements, how-to guides for agents and developers, engineering deep dives and thought leadership, every number linked to its record.
https://one.semurg.io/models: Open language and retrieval models, each with the speed one user sees and the total across many users, generated from the release record.
https://one.semurg.io/clusters: A Semurg cluster runs one engine across several machines: data and work spread over every disk and core of every node. Start on a free first node, add licensed nodes as your data grows.
https://one.semurg.io/performance: Write, read, traverse and scan, measured on the whole cluster at every release, with the machine, the door, the concurrency, the utilisation and where the data was served from behind each figure, and its trend across releases.
https://one.semurg.io/benchmark: Graph, vector, columnar, key-value, time-series, object, document, search, streaming, vector + graph RAG and knowledge graph measured on Semurg r11.118 to r11.127 against Neo4j, ArangoDB, FalkorDB, ArcadeDB, SurrealDB and others: the same question, the same answer and the same machine.
https://one.semurg.io/durability: What happens to your data when a Semurg node is killed, its disk fills or slows, or the power is cut: measured on published releases, with results pending where a test has not run yet.
https://one.semurg.io/cloud: Semurg Cloud will rent you a dedicated server with Semurg already installed: one customer per machine, your SSH key the only login, updates from the Marketplace. Coming soon.
https://one.semurg.io/pricing: A flat licence per node: bought once for the life of that hardware, or annually at the lifetime price spread over a five-year working life. The first node is free, forever. Support is optional at 20% of the lifetime list price per year, and updates are free from the Marketplace.
https://one.semurg.io/consulting: We build an organisation's enterprise in a box on Semurg: its databases, object stores and documents synced into one knowledge graph with an ontology, and persistent agents working on it, on your own hardware. Priced on request; the node licences are bought separately.
https://one.semurg.io/install: Download the installer, check it against the published checksums, and run a node on your own machine. The first node is free, forever. No account, no upload, no call home.
https://one.semurg.io/contact: Talk to the two people who built Semurg. Email [email protected]: a real person reads every message, and replies. Tell us what you are working on and what you need the engine to do.
