A local-first memory system for AI-agent teams — not just giving one agent a memory, but a shared memory fabric for a fleet of agents working together: private, team, and project-scoped memories behind a hard ACL, associative recall, and federated sync that keeps a mesh of nodes (and their org structure) in agreement. One SQLite file, zero required dependencies, Apache-2.0.
Why
Local-first memory engine for AI-agent teams: team/project ACL, recall, and federated sync.

Real work happens in teams of agents — a project might mix Claude Code, Codex, OpenClaw, and several Hermes profiles, across multiple teams and projects, on one machine or many. They need to share the right knowledge with the right teammates and keep private what should stay private:
Per-agent memory is the floor, not the ceiling: durable facts, preferences, procedures, and lessons that survive across sessions.
Team & project memory is the point: a team sees team:<id> memory; a project (a subset of the team) sees project:<id> memory; nothing leaks across the boundary. Membership is first-class and manageable, and drives the ACL.
Federation keeps a mesh honest: memories and the org structure (teams/projects/memberships) converge across nodes, so project:<id> means the same thing everywhere.
Local-first avoids the latency, cost, and privacy tradeoffs of cloud memory platforms — memories live in a local SQLite file, and each prompt receives only the relevant, budgeted slice.
Features
Local-first, zero-dependency core — one SQLite file (FTS5), no server required. pip install and go.
Teams & projects, first-class — teams are sets of node members; a project's members are a subset of its team. team:<id> memory reaches the whole team, project:<id> memory only that project — a hard ACL, managed in the console/CLI/API. Removing a member re-scopes recall instantly; deleting a scope revokes its memory.
Federated across nodes, with a real trust model — portable bundles + peer sync converge memories, links, profiles, and the org structure (teams/projects/memberships) with last-writer-wins + tombstones. Per-peer policy (shared/full/team:/project:) is an enforced authorization scope: a peer can only assert membership within its own scope and can only shrink a memory's visibility, never widen it — no cross-scope escalation from a bundle.
Revocation that propagates — an independent ACL clock carries a post-hoc share/revoke across the mesh, so revoking access actually retracts it on peers that already synced the memory — without disturbing the decay clock.
Requester-aware ACL — every agent has private, agent, team, project, and global memories; visibility is a hard gate enforced before ranking, never a soft score. Candidate indexes return IDs only; content is re-read through the gate.
Dynamic context packs — token-budgeted, auditable memory selection per prompt (context_pack_report() explains every include/exclude decision).
Truth arbitration — duplicate suppression, contradiction detection (CONFLICT markers), and reserved budget for core memories.
Associative recall (resonance) — an authoritative memory_links graph lets related memories surface even when they share no query terms; traversal is ACL-safe (invisible nodes are untraversable).
Hebbian reinforcement — memories recalled together grow stronger links (record_recall, or auto_reinforce=True on context packs); unhelpful recalls weaken links and confidence (helpful=False).
Per-agent recall profiles — different agent personas weight memory types differently (an engineer leans on procedure, a companion on preference); profiles persist in the database and re-weight ranking only, never bypassing ACL.
Memory lifecycle — exponential/linear decay, pinning, hard expiry, and a write-side consolidate() pass that merges duplicates and synthesizes strongly co-recalled clusters into concept memories.
Optional sidecars — semantic vector candidates (turbovec), MCP server, and a FastAPI Web UI, all behind extras; every candidate rejoins SQLite and passes hard gates before use.
How it compares
Most agent-memory systems optimize for LLM-driven extraction at hosted scale.
AgentMemoryOS optimizes for a different point: local-first, team-scoped, and
federated — memory you run yourself, shared across a fleet under a hard ACL.
This is a positioning comparison (architecture, not a benchmark); verify each
row against the projects' current docs.

Mem0 and Zep are strong at LLM-based extraction and managed-scale retrieval —
things AgentMemoryOS deliberately doesn't do. Reach for AgentMemoryOS when you
want a dependency-light memory you own, shared correctly across a team of
agents, that keeps working offline and syncs on your terms.
Or pick pieces: agent-memory-os (core, zero dependencies), [api] (Web UI), [mcp] (MCP server), [semantic] (turbovec vector recall).
Docker: the prebuilt multi-arch image is the complete AgentMemoryOS (web console + MCP server + CLI); the first argument picks the mode:
docker run -p 8000:8000 -v amos-data:/data yamantaka520/agent-memory-os # web console (default)
docker run -i --rm yamantaka520/agent-memory-os mcp # stdio MCP server
docker run --rm -v amos-data:/data yamantaka520/agent-memory-os check # any CLI command
Or docker compose up -d. Console at http://localhost:8000, memories persist in a volume. See the Docker guide (Docker Hub image + a two-node sync mesh).
Requires Python 3.11+ with SQLite FTS5 (included in standard CPython builds).
After installing, run two commands:
agent-memory doctor # verifies FTS5, turbovec, and the other extras
# (add --install to auto-install anything missing)
agent-memory token create # protects the Web UI API with a bearer token
The token is stored at <home>/web_token (mode 600); agent-memory-web picks
it up automatically and the console prompts for it on first use. Manage it
later with agent-memory token show|rotate|disable. Two narrower tiers exist:
--readonly (GET-only) and --sync (federation routes only — hand this to a
peer instead of the admin token).
Quickstart
Prefer a runnable script? examples/team_memory.py shows three agents sharing one store under a hard ACL in ~40 lines — python examples/team_memory.py.
from agent_memory_os import MemoryClient, RecallProfile
client = MemoryClient(home="~/.agent-memory")
# Write memories with ownership and visibility
client.add("User prefers dark mode.", owner="mizuki", type="preference",
visibility=[]) # private to owner
client.add("Deploy target is port 8000.", owner="neo", type="environment",
visibility=["global"]) # visible to every agent
# Requester-aware search: each agent sees only what it may see
hits = client.search("deploy port", requester_agent_id="neo")
# Token-budgeted context pack for the prompt, with reinforcement loop closed
pack = client.context_pack("deploy port", requester_agent_id="neo",
max_tokens=1200, auto_reinforce=True)
# Associate memories; linked memories resonate into future recalls
a = client.add("Staging deploy failed with database lock.", visibility=["global"])
b = client.add("Always snapshot before schema changes.", visibility=["global"])
client.link(a.id, b.id, relation="caused_by", weight=0.8)
# Persist an agent persona: soft ranking bias per memory type
client.save_profile(RecallProfile(agent_id="neo",
type_weights={"procedure": 1.5, "note": 0.7}))
# Periodic hygiene: merge duplicates, synthesize concept memories
client.consolidate()
Architecture
query
-> candidate providers (FTS5 | vector sidecar | resonance graph | fallback)
-> merge/dedupe by stable memory_id
-> rejoin authoritative rows from SQLite
-> ACL hard gate -> expires_at hard gate
-> scoring (relevance x importance x confidence x freshness x reinforcement)
-> per-agent profile re-weighting (soft)
-> truth arbitration + context budget allocation
Design invariants:
The SQLite memories table is the single source of truth; FTS/vector indexes are disposable and rebuildable (rebuild_indexes()).
Candidate providers return IDs and scores only — content is always re-read through SQLite behind the ACL and expiry hard gates.
Association edges (memory_links) are authoritative data, survive index rebuilds, decay when unused, and never let an invisible memory bridge two visible ones.
AgentMemoryOS uses two storage layers with strictly different authority:
SQLite (always on) is the single source of truth: memories, links,
profiles, and the FTS5 lexical index all live in one memories.db file.
turbovec (installed with [full] / [semantic]) is the semantic vector
engine: an in-memory quantized index that recalls memories by meaning rather
than keywords. It is deliberately disposable — it returns candidate
memory_ids and scores only; every candidate rejoins SQLite and passes the
ACL/expiry hard gates before its content can be used, and the index can be
dropped and rebuilt at any time without touching the truth store.
semantic="auto" wires in a self-syncing turbovec index over a built-in
deterministic hashing embedder (no model downloads; typo- and
morphology-tolerant lexical vectors). The index rebuilds itself whenever the
memories table changes and degrades silently to lexical + resonance recall
when the backend isn't installed. For deeper semantics, plug any embedding
model into TurbovecSemanticCandidateProvider.from_vectors(...) with your
own embed_query. agent-memory doctor confirms the backend is importable.
Archived memories leave recall entirely but stay restorable (Web UI → Tools →
Retention & archive, or POST /api/archive/{id}/restore). Pinned and
authority-track memories are never archived by decay. Databases self-migrate
through a versioned, forward-only migration table (agent-memory check
reports the schema version).
Backups use SQLite's online backup API, so they are consistent even while
agents are writing. --keep N rotates out older backups in the same name
series (and can never delete the live database). Disposable indexes rebuild
automatically after a restore.
Upgrades & health.agent-memory update checks PyPI, upgrades, and restarts
the running console; --check reports only. Point health checks at GET /healthz
(200/503) and a Prometheus scraper at GET /metrics.
Multi-agent projects
One project can mix Claude Code, Codex, OpenClaw, and multiple Hermes
profiles against a single store. Register each agent with its teams —
in the console's Agents tab or via API — and team members automatically
see team:<project> memories with no extra wiring:
Or declare the whole fleet as code — <home>/agents.toml is re-applied
every time the store opens (file-listed agents are file-authoritative;
manually registered agents are untouched):
[agents.cc-main]
kind = "claude-code"
teams = ["apollo", "shared-infra"] # multiple teams = multiple projects
[agents.hermes-neo]
kind = "hermes"
teams = ["apollo", "ops"]
Each MCP server declares its identity with AGENT_MEMORY_AGENT_ID, so
memories default to that agent as owner and every recall carries its team
ACL. Ship one project's shared memory to another host with
agent-memory sync export apollo.jsonl --team apollo.
Federation (multi-host sync)
# on the host being joined: mint a sync-scoped token for the peer
agent-memory token create --sync # prints amos_sync_… (federation routes only)
# one-time, on the joining host
# easiest: pairing (one command on each side — tokens/mesh key exchanged for you)
# on the existing node: agent-memory team invite apollo
# on the joining node: agent-memory join <code> --url http://that-node:8000
# or wire a peer by hand:
agent-memory peers add https://other-host:8000 --peer-token <their sync token>
# converge with every registered peer (pull + push, deterministic merges)
agent-memory sync auto
Peers are stored per-home; sync auto (or the console's "Sync mesh now")
converges bidirectionally with each peer — last-writer-wins on memories and
profiles, strongest-wins on links — and unreachable peers fail individually,
never fatally. File bundles (sync export/import) cover air-gapped moves.
Pair with agent-memory service install and a cron/timer entry for
continuous mesh sync.
Encrypt the wire. Give every node the same mesh key and sync bundles are
encrypted app-layer (Fernet), so memory content stays confidential even over
plain HTTP or through a proxy — the key is a separate secret that never travels
on the wire:
agent-memory sync genkey # prints amos_sk_… ; needs the [secure-sync] extra
export AGENT_MEMORY_SYNC_KEY=amos_sk_… # set the SAME value on every node
The sync-scoped token still rides in the Authorization header, so prefer
https:// peer URLs (certificate-verified) for non-localhost peers to protect
the token too. See SECURITY.md for the exact guarantees.
Agent integrations
Step-by-step guides for wiring AgentMemoryOS into common agents — click a tile:
Hermes Agent gets a native memory-provider plugin (not just MCP):
pip install agent-memory-os && agent-memory hermes install, then pick
agent-memory-os in hermes memory setup — recall is injected every turn and
amos_* tools carry the team/project ACL. No API key, no LLM. See the
Hermes guide.
Any MCP-capable agent can use the same pattern: run
python -m agent_memory_os.mcp_server as a stdio MCP server pointing at a
shared AGENT_MEMORY_HOME.
Wire it into Claude Code in one line (set the agent identity so memories are owned correctly):
claude mcp add agent-memory --env AGENT_MEMORY_AGENT_ID=cc-main -- python -m agent_memory_os.mcp_server
Tools (12): memory_add (with a share arg for team/project/global), memory_search, memory_context_pack, memory_orchestrate_context, memory_link, memory_update, memory_share, memory_recall_feedback, memory_consolidate, memory_offload_context, memory_reload_context, memory_snapshot_diff. Set AGENT_MEMORY_AGENT_ID so each agent acts under its own identity — and two agents pointed at the same home instantly share team:/project: memories.
The console speaks English, 繁體中文, 简体中文, 日本語, and 한국어 — auto-detected from the browser, switchable in the header. It ships with a stats dashboard (scope/type/relation breakdowns, 14-day activity, most-recalled memories), search and recency browsing (memory cards with in-place editing, feedback, links, and delete actions), an interactive association-graph view, a context-pack preview with per-memory decisions, and add/link/consolidate tools — all driven by a global "acting as" identity.
Search, browse, graph, recall feedback, and context-pack accept requester_agent_id and enforce the same ACL hard gates as the SDK. Requests without a requester run in unrestricted admin view — bind to localhost only, or require a bearer token on every API route with --token <secret> (or AGENT_MEMORY_WEB_TOKEN).
Note: keep the --home database on a local disk. Network filesystems (NFS/SMB) can fail SQLite FTS5 schema creation with database is locked.
Run as a login service (macOS / Linux / Windows)
agent-memory service install [--host 127.0.0.1] [--port 8000]
agent-memory service status | start | stop | restart | uninstall
install registers the console with the native service manager so it starts
automatically at login and restarts on failure — launchd LaunchAgent on
macOS, a systemd user unit on Linux, a Task Scheduler logon task on Windows.
No admin rights required; the service runs the exact Python environment it
was installed from, and logs to <home>/logs/web.log. On Linux, run
loginctl enable-linger $USER if it must start at boot without a login.
Add --dry-run to preview the actions. CI runs the full test suite on
Ubuntu, macOS, and Windows across Python 3.11–3.13.
Development
pip install -e '.[dev]'
pytest
Status
Stable — 1.x. The contracts above are implemented, covered by the test
suite (300+ tests across a 3-OS CI matrix, plus a migration upgrade-path job),
and audited by repeated fan-out code + security reviews (reports under
docs/reviews/). Performance is verified at 10k memories (add
0.17 ms, search <1 ms, context-pack 7.8 ms). The database self-migrates forward;
see the CHANGELOG for what each release added.
