GrayMatter

\n $\"Documentation\"$ \n $\"CI\"$ \n $\"Go$ \n $\"Latest$ \n $\"Glama$ \n $\"Coverage$ \n $\"Platforms\"$ \n $\"License\"$ \n

\n
\n\nAI agents forget everything between sessions. GrayMatter gives them persistent memory, a self-building knowledge graph, and cuts context tokens by 90%.\n

\nOne binary. Drop it in. Run it. No Docker, no databases, no config files, no cloud accounts, no bullshit.\n

\nGeneral-purpose MCP server. Zero vendor lock-in.\n
\nWorks with Claude Code, Cursor, Codex, OpenCode, Antigravity — and any MCP-compatible client.\n
\nAlso a plain Go library if you don't use MCP.\n

\nFree. Offline. No account required.\n\n
\n

\n\n---\n\n## Why\n\nEvery AI agent is **stateless by default**. Each run re-injects the full conversation history — and that history grows linearly. Two prompts in and you've already burned half of your daily quota.\n\nThat's not just a memory problem. That's a money and performance problem.\n\n**Mem0, Zep, Supermemory** solve this — but they're Python/TypeScript-only and require a running server. The Go ecosystem has no production-ready, embeddable, zero-dependency memory layer for agents.\n\nThat gap is GrayMatter.\n\n

\n $\"Context$ \n

\n\n

\n~90% reduction in context tokens — versus full-history injection.
\nRemembers what a sliding window forgets: facts planted 96 sessions back come back 83% of the time.
\nContext quality improves over time as consolidation surfaces only what matters.
\nNo Docker. No Redis. No API key required for storage.

\nDrop it in once. It auto-connects to Claude Code, Cursor, Codex, OpenCode, Antigravity — any MCP-compatible client picks it up automatically.\n

\n\n---\n\n## Knowledge Graph\n\nYour agent doesn't just remember facts — it builds a map of how they connect.\n\nRun the daemon with `--kg` and every consolidation cycle extracts typed\nentities (person, organization, project) and links the ones that appear\ntogether. No manual tagging. No configuration. The graph builds itself from\nordinary use.\n\n

\n $\"Knowledge$ \n

\n\n

\nEvery edge carries receipts: the fact IDs that produced it.
\nExport to Obsidian with one command — entities become notes,
\nconnections become wikilinks, and the whole graph renders natively.\n

\n\n```bash\ngraymatter daemon run --kg # that's it — the graph builds itself\n```\n\nThe graph as one self-contained page — inline force-directed SVG, zero\nexternal assets, works offline. Hover any edge to see the fact IDs that\nproduced it:\n\n```bash\ngraymatter kg render --out graph.html\ngraymatter kg render --out graph.dot # Graphviz, for your own layout\ngraymatter doctor --graph --html # analytics + this render in one go\n```\n\nWatch it build, one frame per session:\n\n```bash\nscripts/kg-timelapse.sh # deterministic corpus -> frames -> GIF\n # or anywhere: scripts/Dockerfile.kg-timelapse\n```\n\n---\n\n## Observability\n\nYou can't improve what you can't see.\n\n`graymatter tui` opens a live terminal dashboard with everything your\nagent memory is doing — no extra setup required.\n\n

\n $\"GrayMatter-TUI\"$ \n

\n\n**What you get at a glance:**\n\n- **Facts** — total stored, distributed across agents\n- **Memory cost** — KB on disk (text + embeddings), not tokens\n- **Recalls** — cumulative access count across all sessions\n- **Health** — percentage of facts above relevance threshold (weight > 0.5)\n- **Token cost (30d)** — real spend breakdown by model, with cache hit rate\n- **Agent activity** — facts vs recalls per agent, side by side\n- **Weight distribution** — how consolidated your memory is over time\n- **Activity timeline** — facts created per day, last 30 days\n\nThe dashboard auto-refreshes every 5 seconds. Press `1–4` to switch tabs,\n`r` to force refresh, `q` to quit.\n\n`graymatter doctor --graph` extends visibility to the knowledge graph itself:\nhubs by degree, articulation points, orphans, and a declared connectivity\nratio — printed or emitted as JSON.\n\n---\n\n## What GrayMatter gives you\n\n| | |\n|---|---|\n| **Persistent memory** | Facts survive across sessions. Recall by meaning, not just keyword |\n| **90% token reduction** | Top-8 relevant facts instead of full-history injection |\n| **Automatic hooks** | Claude Code injects routine recall every turn; MCP remains available for writes and focused searches (`graymatter hooks install`) |\n| **Receipts, not vibes** | `recall --explain` returns why each fact ranked: per-signal ranks, fused score, provenance |\n| **Knowledge graph** | Typed entities and co-mention edges, auto-populated from ordinary use |\n| **Self-curation** | `memory_reflect` lets the agent add, update, forget, and link its own memories |\n| **Context block** | Projects top facts into CLAUDE.md / AGENTS.md inside a token budget (`context-sync`) |\n| **Free auditor** | `doctor --audit` measures tokens, duplicates, staleness, and marker conflicts in any instruction file |\n| **Deterministic decay** | 30-day half-life; facts fade when nothing touches them. Tombstones, never deletes |\n| **Single binary** | ~10 MB static. No Docker, no Redis, no config files, no cloud accounts |\n\n---\n\n## Quick start\n\nInstall and see it working in under a minute — no API keys, no Ollama:\n\n```bash\ngo install github.com/angelnicolasc/graymatter/cmd/graymatter@latest\ngraymatter demo # a working store with 3 agents, then the TUI opens\ngraymatter init # wire YOUR project: MCP config + memory block\ngraymatter init --hooks # Claude Code: memory injected every turn\ngraymatter doctor # verify everything\n```\n\n`graymatter init --global` still performs that normal setup in the current\ndirectory. It additionally installs the managed memory instructions in Claude\nCode and OpenCode's home-scoped instruction files. It does **not** globalize\nproject-scoped MCP configs: each repository must be wired separately with\n`graymatter init` or manual client configuration. Codex is the exception in\nthe table below because its MCP config is already home-scoped.\n\n`graymatter demo` seeds a scratch store, runs consolidation, and opens the\nTUI — then `graymatter kg render --out kg-graph.html` shows the graph it\nbuilt. Restart your editor. Five memory tools are live.\n\n

\n\n

MCP client wiring — Claude Code, Cursor, Codex, OpenCode, Antigravity, and anything else

\n\n`graymatter init` auto-wires every supported client at once. Existing entries\nfrom other MCP servers are merged, never overwritten.\n\n| Client | Config file | Scope |\n|--------|-------------|-------|\n| Claude Code | `.mcp.json` | project |\n| Cursor | `.cursor/mcp.json` | project |\n| Codex (OpenAI) | `~/.codex/config.toml` | home |\n| OpenCode | `opencode.jsonc` | project |\n| Antigravity (Google) | `mcp_config.json` | opt-in |\n| Windsurf | `.windsurf/mcp.json` | project |\n| VS Code Copilot Agent | `.vscode/mcp.json` | project |\n\n**Also works out of the box:** Pi (reads `.mcp.json` natively), Zed, Cline,\nand any MCP-compatible client — point them at `graymatter mcp serve`.\nPer-client verified configs for 25 clients, including the ones that need a\ndifferent shape (VS Code's `servers` key, Codex TOML, Zed's\n`context_servers`), live in [docs/integrations.md](https://github.com/angelnicolasc/graymatter/blob/main/docs/integrations.md).\nSee [docs/AGENTS.md](https://github.com/angelnicolasc/graymatter/blob/main/docs/AGENTS.md) for tool parameters and query patterns.\n

\n\n---\n\n## Token efficiency\n\nNumbers produced by `go run ./benchmarks/token_count` — real Recall calls,\nkeyword embedder, no LLM required:\n\n| Sessions | Full injection | GrayMatter | Reduction |\n|----------|---------------|------------|-----------|\n| 1 | ~80 tokens | ~80 tokens | 0% |\n| 10 | ~630 tokens | ~550 tokens | 12% |\n| 30 | ~1,880 tokens | ~550 tokens | 71% |\n| 100 | ~6,960 tokens | ~670 tokens | **90%** |\n\n### Does it return the *right* facts?\n\nTokens are only half the question. A second benchmark checks whether the\nreturned facts actually answer the query, against a real sliding window:\n\n| | sliding window | GrayMatter | + `MinRelevance` |\n|---|---|---|---|\n| Finds a fact planted 96 sessions ago | 0% | **83%** | 83% |\n| Returns a superseded fact | 0% | 0% | 0% |\n| Tokens per query | 95 | 114 | **64** |\n\nAt equal fact count, relevance-selected facts cost slightly more tokens than a\nwindow's newest-first picks. With `MinRelevance`, GrayMatter drops below the\nwindow's cost while keeping full recall of old facts. Method and per-query\ndetail in [`benchmarks/RESULTS.md`](https://github.com/angelnicolasc/graymatter/blob/main/benchmarks/RESULTS.md).\n\nEvery figure on this page is machine-checked against a live run in CI.\n\n---\n\n## Memory lifecycle\n\n```\nRecall(agent, task) ← hybrid: vector + keyword + recency → top-8 facts\n ↓\nInject into system prompt ← your 3 lines of code\n ↓\nAgent runs\n ↓\nRemember(agent, observation) ← store key facts during/after run\n ↓\nConsolidate() [async] ← summarise + decay + prune + extract entities\n```\n\nConsolidation is the only \"smart\" step. Everything else is deterministic.\n\n### Hooks (Claude Code, opt-in)\n\n`graymatter hooks install` writes the hook block into `.claude/settings.json`\nand after that the hook runner supplies routine recall automatically:\n\n| Hook | What it does |\n|------|--------------|\n| `SessionStart` | Injects the freshest live facts plus project-wide `__shared__` conventions — and re-injects after `/compact` (your memory survives compaction) |\n| `UserPromptSubmit` | Short per-turn recall (top-3 agent + top-3 shared), suppressed when identical to the previous turn; `remember: ` in a prompt is an instant deterministic save, `remember shared: ` saves into the shared namespace every agent reads |\n| `PreCompact` | Deterministic checkpoint before context compaction |\n| `SessionEnd` | Checkpoint + detached consolidation (survives the editor closing) |\n\nHooks and MCP are complementary. Every non-empty hook recall begins with a\nbracketed `GrayMatter hook recall ran` marker naming the namespace it actually\nqueried. This page never spells that marker out in full, so an agent reading\nthe docs cannot mistake them for a live recall. The agent reuses\nonly the newest block available for the session's initial turn. If that ID\nmatches its own, each non-empty section replaces that scope's startup search.\nIf the IDs differ, it reruns both project and `__shared__` searches because\ncross-namespace deduplication may have placed a shared fact in the project\nsection. Missing sections also fall back to MCP. Focused and batch searches,\nwrites, corrections, aliases, and checkpoint tools always remain available.\n\nFailure contract: every error exits 0 with empty stdout and a receipt in\n`/hooks.log` — a broken memory degrades silently, it never breaks\nthe session. `graymatter hooks doctor` verifies registration, the recorded\nbinary path, and store latency; the hot path is machine-checked in\n[`benchmarks/hook_latency`](https://github.com/angelnicolasc/graymatter/blob/main/benchmarks/hook_latency) with hardware-relative\ngates — the recall's marginal cost against the same machine's checkpoint\nbaseline (≤ 200 ms) and in-process scaling (≤ 2.5× of linear at 10k facts) —\nbecause absolute wall-clock numbers on shared CI runners measure the runner\nqueue, not the code. Reference-hardware figure: p99 121 ms user-prompt on a\n10k-fact store, no LLM, localhost only by construction.\n\n### Context block (opt-in)\n\n`graymatter context-sync` projects the highest-weight live facts into a managed\nblock inside CLAUDE.md / AGENTS.md, inside an explicit token budget.\n\nSafety properties:\n\n- Content outside the markers is never touched.\n- Every rewrite leaves the previous file as `.bak`.\n- Hand edits are detected and warned about before overwrite — never silent.\n- Deterministic projection: same store state, same block bytes.\n\n---\n\n## CLI\n\n```bash\n# setup\ngraymatter init # .graymatter/ + MCP wiring\ngraymatter init --kg --hooks # + KG auto-population + Claude Code hooks\ngraymatter demo # scratch store + TUI in one command\n\n# memory\ngraymatter remember \"agent\" \"text\" # store a fact\ngraymatter recall \"agent\" \"query\" # print context\ngraymatter recall \"a\" \"q\" --explain # why each fact ranked (receipts)\ngraymatter revise \"agent\" \"old\" \"new\" # record a correction; recall stops\n # returning the old value, and the\n # receipt names what it replaced\ngraymatter forget \"agent\" \"fact\" # retire a fact with no replacement\n\n# hooks + consolidation\ngraymatter hooks install # Claude Code auto-memory (merge, never\n # overwrite)\ngraymatter hooks doctor # verify hooks, binary path, latency\ngraymatter consolidate \"agent\" # one consolidation cycle\n\n# knowledge graph\ngraymatter kg render --out g.html # self-contained page (or .dot)\n\n# lifecycle + inspection\ngraymatter pin \"agent\" \"fact\" # exempt from decay/pruning (ADR-010)\ngraymatter unpin \"agent\" \"fact\" # restore normal decay\ngraymatter tui # 4-view terminal UI\ngraymatter status # facts, recalls, KG state\ngraymatter doctor # full setup check\ngraymatter doctor --graph --html # KG analytics + visual render\ngraymatter doctor --health # store health audit\ngraymatter doctor --audit [path] # audit any instruction file\n\n# export / serve / measure\ngraymatter export --format obsidian --include-graph\ngraymatter mcp serve # MCP over stdio\ngraymatter server # REST API server (127.0.0.1:8080)\ngraymatter bench # audit published numbers (--hooks, --store)\ngraymatter context-sync # managed context block (opt-in)\n```\n\n---\n\n## Library usage\n\n```go\nimport \"github.com/angelnicolasc/graymatter\"\n\nctx := context.Background()\nmem := graymatter.New(\".graymatter\")\ndefer mem.Close()\n\nif !mem.Healthy() {\n log.Fatalf(\"graymatter: %v\", mem.Status().InitError)\n}\n\nmem.Remember(ctx, \"sales-closer\", \"Maria didn't reply Wednesday.

Testing

\n\nFull suite requires no LLM and no network. Runs clean on Linux, macOS, Windows.\n\n```bash\ngo test -count=1 ./pkg/memory/...\ncd cmd/graymatter && go test -count=1 ./...\n```\n\nCoverage, measured as the multi-platform union in CI (`coverage-union` job):\ncore library ≈ 90%, CLI module ≈ 81%. Gates: core ≥ 82%, CLI ≥ 72%, and they\nonly ratchet upward. Fuzz targets: `FuzzTokenize`, `FuzzUnmarshalFact`,\n`FuzzKeywordScore`, exercised nightly plus a nightly mutation-testing run\nwhose surviving-mutant report feeds the test-writing queue.\n

\n\n

Build from source

\n\n```bash\ngit clone https://github.com/angelnicolasc/graymatter\ncd graymatter\nCGO_ENABLED=0 go build -ldflags=\"-s -w\" -o graymatter ./cmd/graymatter\n```\n

\n\n

Metrics & APM hooks

\n\nThe REST server exposes `/metrics` behind the bearer token. Library users get\n`OnRecall`, `OnPut`, and `OnVectorIndexError` hooks plus a pluggable\n`VectorBackend` interface.\n

\n\n

Security

\n\nNetwork surfaces bind loopback-only with bearer auth. Memory is untrusted input:\nrecalled facts are fenced, never concatenated as system prompt.\nSee [docs/threat-model.md](https://github.com/angelnicolasc/graymatter/blob/main/docs/threat-model.md).\n

\n\n---\n\n## What GrayMatter is NOT\n\nNot tied to any vendor. Not a framework. Not a hosted service. Not a knowledge-base UI. Not trying to win the enterprise memory market.\n\nIt is exactly one thing: **the missing stateful layer for Go agents**, packaged as an MCP server and a library you import in three lines.\n\n---\n\n## How it compares\n\n**Code graphs** parse your source tree and expose symbols, call edges, and blast radius. The repo is the source of truth. GrayMatter never reads your source — facts exist only because something deliberately wrote them, and they carry a 30-day half-life that code graphs must never have, since a stale fact means something changed and a stale code graph means nothing did.\n\n**Context compressors** shrink payloads already moving through the transport. GrayMatter never sees your traffic — the agent writes one distilled sentence and recalls a handful later. Some compressors ship session memory; the difference is scope. They stack.\n\n---\n\n## Roadmap\n\n- [x] Ollama-backed consolidation LLM — shipped in [v0.14.0](https://github.com/angelnicolasc/graymatter/blob/main/CHANGELOG.md): propose/apply with tombstone receipts, fully local ([ADR-011](https://github.com/angelnicolasc/graymatter/blob/main/docs/decisions/011-consolidation-propose-apply.md))\n- [ ] Cross-project memory federation (read-only) — [#12](https://github.com/angelnicolasc/graymatter/issues/12), deferred until a multi-project store demonstrates the need\n- [ ] WebSocket streaming for REST API\n- [ ] MCP 2026-07-28 stateless protocol support\n\n---\n\n*GrayMatter — v0.19.0 — September 2026*\n","changelogMarkdown","videoKey","requiredSecretsJson","publishedAt","priceCents","trialDays",0,"upstream",{"_104":105,"_106":107,"_108":109,"_110":111,"_112":113,"_114":115},"requiredSecrets",[],"tags",[94,95,96,97,98,99,100,101,102,103],"assets",[],"stats",{"_92":81,"_93":81},"ratingAvg","reviewCount","agent-memory","ai-agents","ai-tools","claude-code","cli","context-management","go","offline-first","persistent-memory","self-hosted","topics",[94,95,96,97,98,99,100,116,101,102,103],"license","MIT","language","Go","registryName","io.github.angelnicolasc/graymatter","homepage","https://graymatter.nickcerutti.workers.dev","packages",[],"mcp","ENV",{"_119":120,"_121":122,"_123":124},"ENVIRONMENT","production","TURNSTILE_SITE_KEY","0x4AAAAAAB8-rEI2gNDf_QhU","SENTRY_DSN","https://45fd1229f78089d5c3ee78be128030e1@o4510583261757440.ingest.de.sentry.io/4510584253448272"]
