Your agent forgets why it made decisions. OpenContext fixes that.
The context layer for AI agents — a temporal context graph, memory API, and self-evolving loop in one dependency.
Context is the missing layer. Retrieval answers what happened. OpenContext answers how what happened became what is.
OpenContext keeps the — temporal timelines, belief revision, and provenance.

⭐ If you find opencontext useful, please consider giving us a star on GitHub! It helps more people discover the project and motivates us to keep building. 🙏
OpenContext is the agentic context runtime that sits underneath an agentic application — and the substrate you build your own agent on top of. It is not a UI, a chat surface, or a model provider — it is the glue between the things that make an agent useful: durable memory, retrieval, context correction, multi-platform connectivity, scheduled awareness, and a deterministic loop engine, all behind one dependency.
→ Read docs/architecture.md for the full
data model, the lifecycle of a fact, and the transport surface map.
OpenContext fits teams who need to engineer their context — that is, teams whose day-to-day work runs straight into the problems OpenContext was built to solve. Each bullet spells out the pain and how OpenContext addresses it:
valid_from / valid_until, so "what did we believe last quarter?" is a real, citable query — not a guess.IntegrationRecord hides credentials, rate-limits, and reconnect logic, while platform + messageId is the natural audit trail for personal and work data.packages/loop ships exactly that separation.Third-party memory and long-context recall benchmarks (numbers current as of 2026-08):
Scores above are opencontext self-evaluations on the public datasets, produced by our own harnesses under
benchmark/. They are not Agent Memory Leaderboard (AML) results — AML evaluates against private refined datasets on its own platform. Official AML scores, once our hosted submission completes, will appear on the leaderboard card; seebenchmark/aml-local/for the submission.
There are several ways to get opencontext into your project. Pick the one that matches what you're building.
pnpm add @melandlabs/opencontext
A 30-second example of the memory API:
import { createMemoryStore, getRawMessageManager } from "@melandlabs/opencontext";
// The store defaults to SQLite at MEMORY_STORE_DB_PATH (./memory.db by
// default). Each call returns an awaitable handle.
const store = await createMemoryStore();
const messages = await getRawMessageManager();
// A message is one fact: a single piece of content attributed to a user.
// `messageId` makes the call idempotent across re-ingest.
const now = Date.now();
await messages.storeMessages([
{
messageId: "msg-1",
userId: "u-42",
content: "User prefers dark mode in all tools",
platform: "test",
botId: "bot-1",
timestamp: now,
createdAt: now,
},
]);
// Unified search fans out to memory + insights + knowledge. Sources you
// haven't wired up just emit a warning — fine for a single-backend deploy.
const hits = await store.search({
userId: "u-42",
query: "What does the user prefer?",
limit: 5,
});
// hits.count — number of results
// hits.sources — which sub-indexes were actually consulted
// hits.warnings — per-source degradation (e.g. missing embedder)
Write and query memory straight from the command line. add writes a
single raw message to the active manager with no LLM roundtrip, and
search runs a unified read across memory, insights, and knowledge.
pnpm add -g @melandlabs/opencontext # puts the `opencontext` bin on PATH
# Write a fact (auto-fills messageId, platform="cli", timestamp=now)
opencontext add --text "Rust achieves memory safety without GC"
# Write with full provenance for later consolidation
opencontext add \
--text "Discussed Q4 roadmap with the team" \
--source "meeting://2026-08-20" --kind experience \
--tag topic=roadmap --tag team=eng
# Plain hybrid search (RRF across memory + insights + knowledge)
opencontext search --query "memory safety" --k 5
# Inspect what would have been sent to the LLM, no synthesis call
opencontext search --query "what did we chat about last weekend" --context-only
# Script-friendly JSON
opencontext search --query "x" --json | jq '.results[].id'
add accepts --user (default "default"), --bot (default "default"),
--platform, --channel, --person, --source, --kind, --at,
and repeatable --tag key=value. search accepts --mode {auto|lex|sem},
--k, --threshold, repeatable --bot / --kind, --since / --until,
and --explain to surface reasoning + warnings alongside the hits.
Run opencontext <command> --help for the full flag list. See the
Getting Started tutorial
for the full flag reference and worked examples.
pnpm add -g @melandlabs/opencontext # puts the `opencontext` bin on PATH
opencontext http \
--embedding-provider local \
--memory-backend sqlite-vec \
--host 127.0.0.1 --port 7421
# Or, without a global install, via npx:
npx -y @melandlabs/opencontext http \
--embedding-provider local --memory-backend sqlite-vec
curl http://127.0.0.1:7421/health
opencontext mcp \
--embedding-provider local \
--memory-backend sqlite-vec
OpenContext is available as a DSH plugin that gives any DSH agent durable memory and retrieval-augmented context:
# Install the plugin from npm
dsh plugin --profile web add dsh-opencontext
# Confirm it's mounted
dsh --profile web --dump-config | grep dsh-opencontext
# ... should contain `id: dsh-opencontext`
# Start DSH web and verify
dsh web
# Visit http://127.0.0.1:3080/plugins and confirm dsh-opencontext shows "Enabled"
The plugin exposes 16 oc_* tools (e.g., oc_search, oc_remember, oc_memory_list) and automatically:
See plugins/dsh-opencontext/README.md for configuration options and the full tool reference.
opencontext doctor # human-readable health checks
opencontext doctor --json # CI-friendly { ok, exit, results } envelope
opencontext doctor --section memory-store
doctor is read-only and exits 0 on a healthy install. It scans nine
sections (runtime, filesystem, loop, memory-store, embedding,
policies, audit, security, integrations) and reports pass /
warn / fail for each. No auto-fix in v1.

The examples/ workspace ships a runnable example per
capability area. Clone, install, and run:
git clone https://github.com/melandlabs/opencontext.git
cd opencontext/examples
pnpm install
pnpm test
See examples/README.md for the full walkthrough.
OpenContext is not a memory library and not a vector DB. It is a
runtime substrate — the @melandlabs/opencontext package bundles
contracts, memory-store, retrieval primitives, the loop engine, and
the agent runtime behind one dependency.
