What is Lore Context

Lore Context is an open-core control plane for AI-agent memory: it composes context across memory, search, repository graphs, and tool traces; evaluates retrieval quality on your own datasets; routes governance review for sensitive content; and exports memory as a portable interchange format you can move between backends.

It does not try to be another memory database. The unique value is what sits on top of memory:

• Context Query — single endpoint composes memory + web + repo + tool traces, returns a graded context block with provenance.
• Memory Eval — runs Recall@K, Precision@K, MRR, stale-hit-rate, p95 latency on datasets you own; persists runs and diffs them for regression detection.
• Governance Review — six-state lifecycle (candidate / active / flagged / redacted / superseded / deleted), risk-tag scanning, poisoning heuristics, immutable audit log.
• MIF-like Portability — JSON + Markdown export/import preserving provenance / validity / confidence / source_refs / supersedes / contradicts. Works as a migration format between memory backends.
• Repo Graph — deterministic repository indexing (files, symbols, imports, calls, routes, tests) exposed as API routes and read-only MCP tools so agents ground repository answers in a stable project-context contract.
• Multi-Agent Adapter — first-class agentmemory integration with version probe + degraded-mode fallback; clean adapter contract for additional runtimes.

When to use it

Quick Start

# 1. Clone + install
git clone https://github.com/Lore-Context/lore-context.git
cd lore-context && pnpm install

# 2. Run the quickstart helper and inspect the activation report
pnpm quickstart -- --dry-run --activation-report

# 3. Generate a real API key (do not use placeholders in any environment beyond local-only dev)
export LORE_API_KEY=$(openssl rand -hex 32)

# 4. Start the API (file-backed, no Postgres required)
pnpm build && PORT=3000 LORE_STORE_PATH=./data/lore-store.json pnpm start:api

# 5. Write a memory
curl -H "Authorization: Bearer $LORE_API_KEY" -H "Content-Type: application/json" \
  -X POST http://127.0.0.1:3000/v1/memory/write \
  -d '{"content":"Use RDS as truth store and Qdrant as the derived recall index for Lore Context production.","memory_type":"project_rule","project_id":"demo"}'

# 6. Query context, then inspect the returned traceId in the Evidence Ledger
curl -H "Authorization: Bearer $LORE_API_KEY" -H "Content-Type: application/json" \
  -X POST http://127.0.0.1:3000/v1/context/query \
  -d '{"query":"production storage","project_id":"demo","token_budget":1200}'

For the public website quickstart, see lorecontext.com/quickstart. For full setup (Postgres, Docker Compose, Dashboard, MCP integration), see docs/getting-started.md.

The canonical alpha quickstart is git clone + pnpm quickstart. Lore does not currently publish or claim a public @lore-context/quickstart npm package. The MCP stdio server is published separately as @lore-context/server for registry and client distribution, and the SDK middleware ships as @lore-context/sdk-middleware (npm) and lore-context-middleware (PyPI).

For AI-readable discovery, the website publishes /llms.txt and /llms-full.txt from public documentation only. The Official MCP Registry entry is published, and additional distribution drafts live under docs/distribution. Launch drafts live under docs/launch, and design partner intake under docs/design-partners. The public benchmark page is a reproducible methodology and small smoke-run report, not a competitive benchmark-win claim.

Architecture

The diagram below shows the full open-core plus hosted-production shape. In the public OSS repo, local file/Postgres deployment is supported directly; hosted Google sign-in, AWS SQS workers, private embeddings, billing, and multi-tenant operations are commercial hosted-cloud surfaces.

What's in v2.1.0

v2.1.0 is the Repo Graph API and MCP Tools release. It makes Lore's own repository graph a first-class agent memory surface: deterministic TypeScript/JavaScript repository indexing for files, symbols, imports, calls, routes, tests, and process hints, exposed through API routes and read-only MCP tools so agents ground repository answers in a stable project-context contract instead of ad hoc text search.

v2.1.0 is the current open-core source line. The hosted Lore Cloud production line also runs v2.1.0 on the commercial AWS/Qdrant/private-embedding substrate, but hosted operations, billing, production release automation, and Secret Vault runtime stay in Lore-Context/lore-cloud.

See CHANGELOG.md for the full release history.

Current release status

v2.1.0 is the current source, hosted production, and release line. It deployed to AWS production and the public website through the optimized release flow: immutable arm64-first artifacts, staging API smoke, production API deploy, isolated website deploy, post-release audit, and tag/release closure. External checks confirm https://api.lorecontext.com/health returns status=ok, /openapi.json reports 2.1.0, and https://lorecontext.com/status.html contains v2.1.0.

Production keeps the v1.1+ RDS / SQS / memory-worker / Qdrant cloud shape, uses lore_memories_v12 as the Qdrant collection, keeps 1024-dim pgvector for the Postgres path, and adds the additive repo graph schema (apps/api/src/db/schema-v21-repo-graph.sql).

See docs/release-status.md for the current public-safe status snapshot and docs/release-notes/v2.1.0.md for the full release notes.

Release focus

The v2.1 release makes Lore's repository graph a first-class agent memory surface. The goal is to let agents answer "where is X defined", "what calls this", and "what breaks if I change this" against a deterministic, stable project-context contract rather than ad hoc text search:

• @lore/repo-graph — deterministic TypeScript/JavaScript repository indexing for files, symbols, imports, calls, routes, tests, and process hints.
• API routes: POST /v1/repo/graph/query, POST /v1/repo/symbol/context, POST /v1/repo/impact, and POST /v1/repo/detect-changes.
• MCP tools: repo.graph_query, repo.symbol_context, repo.impact, and repo.detect_changes (read-only).
• context_query(repo) now uses provider-backed repo graph evidence when available, with an honest unavailable fallback when repo graph storage is not configured.
• The repo graph Postgres schema is additive — it sits on top of the existing production schema and is applied during production/staging schema setup.

Root and API package versions report 2.1.0 so /openapi.json matches the release tag. The release train uses the optimized split API/website deployment guardrails introduced after v2.0.9.

See docs/project-plan.md, docs/roadmap.md, and docs/release-governance.md.

Integrations

Lore Context speaks MCP and REST and integrates with most agent IDEs and chat frontends:

Deployment

All deployment paths require explicit secrets. Local/private paths require POSTGRES_PASSWORD, LORE_API_KEYS, and dashboard auth. Hosted deployments also need RDS, SQS, Qdrant, embedding-service, OAuth, tunnel configuration, and the production runtime exports. The scripts/check-env.mjs script refuses production startup if any value matches a placeholder pattern.

Security

v2.1.0 keeps the local/private deployment posture and the hosted cloud guardrails for ordinary-user access:

• Authentication: API-key bearer tokens with role separation (reader/writer/admin) and per-project scoping. Empty-keys mode fails closed in production.
• Rate limiting: per-IP + per-key dual bucket with auth-failure backoff (429 after 5 fails in 60s, 30s lockout).
• Dashboard: Google session flow for the hosted product; HTTP Basic Auth remains available for local/private operator deployments.
• Containers: all Dockerfiles run as non-root node user; HEALTHCHECK on api + dashboard.
• Secrets: zero hardcoded credentials; all defaults are required-or-fail variables. scripts/check-env.mjs rejects placeholder values in production.
• Governance: PII / API key / JWT / private-key regex scanning on writes; risk-tagged content auto-routed to review queue; immutable audit log on every state transition.
• Memory poisoning: heuristic detection on consensus + imperative-verb patterns.
• MCP: zod schema validation on every tool input; mutating tools require reason (≥8 chars) and surface destructiveHint: true; upstream errors sanitized before client return.
• Worker isolation: capture, embedding, graph, connector, and backfill jobs run through AWS SQS queues with DLQs; Qdrant is a derived index and RDS remains authoritative.
• Logging: structured JSON with auto-redaction of content, query, memory, value, password, secret, token, key fields.
