agentmemory — Persistent memory for AI coding agents

Your coding agent remembers everything. No more re-explaining.
Persistent memory for Claude Code, Cursor, Gemini CLI, Codex CLI, pi, OpenCode, and any MCP client.

The gist extends Karpathy's LLM Wiki pattern with confidence scoring, lifecycle, knowledge graphs, and hybrid search.
agentmemory is the implementation.

95.2% retrieval R@5 92% fewer tokens 51 MCP tools 12 auto hooks 0 external DBs 827 tests passing

Quick StartBenchmarksvs CompetitorsAgentsHow It WorksMCPVieweriii ConsoleConfigAPI


agentmemory works with any agent that supports hooks, MCP, or REST API. All agents share the same memory server.

| Claude Code Claude Code 12 hooks + MCP + skills | OpenClaw OpenClaw MCP + plugin | Hermes Hermes MCP + plugin | Cursor Cursor MCP server | Gemini CLI Gemini CLI MCP server | OpenCode OpenCode MCP server | Codex CLI Codex CLI MCP server | Cline Cline MCP server | | --- | --- | --- | --- | --- | --- | --- | --- | | Goose Goose MCP server | Kilo Code Kilo Code MCP server | Aider Aider REST API | Claude Desktop Claude Desktop MCP server | Windsurf Windsurf MCP server | Roo Code Roo Code MCP server | Claude SDK Claude SDK AgentSDKProvider | Any agent REST API |

Works with any agent that speaks MCP or HTTP. One server, memories shared across all of them.


You explain the same architecture every session. You re-discover the same bugs. You re-teach the same preferences. Built-in memory (CLAUDE.md,.cursorrules) caps out at 200 lines and goes stale. agentmemory fixes this. It silently captures what your agent does, compresses it into searchable memory, and injects the right context when the next session starts. One command. Works across agents.

What changes: Session 1 you set up JWT auth. Session 2 you ask for rate limiting. The agent already knows your auth uses jose middleware in src/middleware/auth.ts, your tests cover token validation, and you chose jose over jsonwebtoken for Edge compatibility. No re-explaining. No copy-pasting. The agent just knows.

npx @agentmemory/agentmemory

New in v0.9.0 — Landing site at agent-memory.dev, filesystem connector (@agentmemory/fs-watcher), standalone MCP now proxies to the running server so hooks and the viewer agree, audit policy codified across every delete path, health stops flagging memory_critical on tiny Node processes. Full notes in CHANGELOG.md.

Compatibility: this release targets stable iii-sdk ^0.11.0 and iii-engine v0.11.x.

Try it in 30 seconds

# Terminal 1: start the server
npx @agentmemory/agentmemory

# Terminal 2: seed sample data and see recall in action
npx @agentmemory/agentmemory demo

demo seeds 3 realistic sessions (JWT auth, N+1 query fix, rate limiting) and runs semantic searches against them. You'll see it find "N+1 query fix" when you search "database performance optimization" — keyword matching can't do that.

Open http://localhost:3113 to watch the memory build live.

Session Replay

Every session agentmemory records is replayable. Open the viewer, pick the Replay tab, and scrub through the timeline: prompts, tool calls, tool results, and responses render as discrete events with play/pause, speed control (0.5×–4×), and keyboard shortcuts (space to toggle, arrows to step).

Already have older Claude Code JSONL transcripts you want to bring in?

# Import everything under the default ~/.claude/projects
npx @agentmemory/agentmemory import-jsonl

# Or import a single file
npx @agentmemory/agentmemory import-jsonl ~/.claude/projects/-my-project/abc123.jsonl

Imported sessions show up in the Replay picker alongside native ones. Under the hood each entry routes through the mem::replay::load, mem::replay::sessions, and mem::replay::import-jsonl iii functions — no side-channel servers.

Upgrade / Maintenance

Use the maintenance command when you intentionally want to update your local runtime:

npx @agentmemory/agentmemory upgrade

Warning: this command mutates the current workspace/runtime. It can update JavaScript dependencies, may run cargo install iii-engine --force, and may pull Docker images.

Implementation details live in src/cli.ts (see runUpgrade around the src/cli.ts:544-595 region).

Claude Code (one block, paste it)

Install agentmemory: run \`npx @agentmemory/agentmemory\` in a separate terminal to start the memory server. Then run \`/plugin marketplace add rohitg00/agentmemory\` and \`/plugin install agentmemory\` — the plugin registers all 12 hooks, 4 skills, AND auto-wires the \`@agentmemory/mcp\` stdio server via its \`.mcp.json\`, so you get 51 MCP tools (memory_smart_search, memory_save, memory_sessions, memory_governance_delete, etc.) without any extra config step. Verify with \`curl http://localhost:3111/agentmemory/health\`. The real-time viewer is at http://localhost:3113.

OpenClaw (paste this prompt)

Install agentmemory for OpenClaw. Run \`npx @agentmemory/agentmemory\` in a separate terminal to start the memory server on localhost:3111. Then add this to my OpenClaw MCP config so agentmemory is available with all 43 memory tools:

{
  "mcpServers": {
    "agentmemory": {
      "command": "npx",
      "args": ["-y", "@agentmemory/mcp"]
    }
  }
}

Restart OpenClaw. Verify with \`curl http://localhost:3111/agentmemory/health\`. Open http://localhost:3113 for the real-time viewer. For deeper memory-slot integration, copy \`integrations/openclaw\` to \`~/.openclaw/extensions/agentmemory\` and enable \`plugins.slots.memory = "agentmemory"\` in \`~/.openclaw/openclaw.json\`.

Full guide: integrations/openclaw/

Hermes Agent (paste this prompt)

Install agentmemory for Hermes. Run \`npx @agentmemory/agentmemory\` in a separate terminal to start the memory server on localhost:3111. Then add this to ~/.hermes/config.yaml so Hermes can use agentmemory as an MCP server with all 43 memory tools:

mcp_servers:
  agentmemory:
    command: npx
    args: ["-y", "@agentmemory/mcp"]

memory:
  provider: agentmemory

Verify with \`curl http://localhost:3111/agentmemory/health\`. Open http://localhost:3113 for the real-time viewer. For deeper 6-hook memory provider integration (pre-LLM context injection, turn capture, MEMORY.md mirroring, system prompt block), copy integrations/hermes from the agentmemory repo to ~/.hermes/plugins/agentmemory.

Full guide: integrations/hermes/

Other agents

Start the memory server: npx @agentmemory/agentmemory

Then add the MCP config for your agent:

| Agent | Setup | | --- | --- | | Cursor | Add to ~/.cursor/mcp.json: {"mcpServers": {"agentmemory": {"command": "npx", "args": ["-y", "@agentmemory/mcp"]}}} | | OpenClaw | Add to MCP config: {"mcpServers": {"agentmemory": {"command": "npx", "args": ["-y", "@agentmemory/mcp"]}}} or use the memory plugin | | Gemini CLI | gemini mcp add agentmemory npx -y @agentmemory/mcp --scope user | | Codex CLI | codex mcp add agentmemory -- npx -y @agentmemory/mcp or add [mcp_servers.agentmemory] to .codex/config.toml | | pi | Copy integrations/pi to ~/.pi/agent/extensions/agentmemory and restart pi | | OpenCode | Add to opencode.json: {"mcp": {"agentmemory": {"type": "local", "command": ["npx", "-y", "@agentmemory/mcp"], "enabled": true}}} | | Hermes Agent | Add to ~/.hermes/config.yaml with memory.provider: agentmemory or use the memory provider plugin | | Cline / Goose / Kilo Code | Add MCP server in settings | | Claude Desktop | Add to claude_desktop_config.json: {"mcpServers": {"agentmemory": {"command": "npx", "args": ["-y", "@agentmemory/mcp"]}}} | | Aider | REST API: curl -X POST http://localhost:3111/agentmemory/smart-search -d '{"query": "auth"}' | | Any agent (32+) | npx skillkit install agentmemory |

From source

git clone https://github.com/rohitg00/agentmemory.git && cd agentmemory
npm install && npm run build && npm start

This starts agentmemory with a local iii-engine if iii is already installed, or falls back to Docker Compose if Docker is available. REST, streams, and the viewer bind to 127.0.0.1 by default.

Install iii-engine manually:

  • macOS / Linux: curl -fsSL https://install.iii.dev/iii/main/install.sh | sh
  • Windows: download iii-x86_64-pc-windows-msvc.zip from iii-hq/iii releases, extract iii.exe, add to PATH

Or use Docker (the bundled docker-compose.yml pulls iiidev/iii:latest). Full docs: iii.dev/docs.

Windows

agentmemory runs on Windows 10/11, but the Node.js package alone isn't enough — you also need the iii-engine runtime (a separate native binary) as a background process. The official upstream installer is a sh script and there is no PowerShell installer or scoop/winget package today, so Windows users have two paths:

Option A — Prebuilt Windows binary (recommended):

# 1. Open https://github.com/iii-hq/iii/releases/latest in your browser
# 2. Download iii-x86_64-pc-windows-msvc.zip
#    (or iii-aarch64-pc-windows-msvc.zip if you're on an ARM machine)
# 3. Extract iii.exe somewhere on PATH, or place it at:
#    %USERPROFILE%\.local\bin\iii.exe
#    (agentmemory checks that location automatically)
# 4. Verify:
iii --version

# 5. Then run agentmemory as usual:
npx -y @agentmemory/agentmemory

Option B — Docker Desktop:

# 1. Install Docker Desktop for Windows
# 2. Start Docker Desktop and make sure the engine is running
# 3. Run agentmemory — it will auto-start the bundled compose file:
npx -y @agentmemory/agentmemory

Option C — standalone MCP only (no engine): if you only need the MCP tools for your agent and don't need the REST API, viewer, or cron jobs, skip the engine entirely:

npx -y @agentmemory/agentmemory mcp
# or via the shim package:
npx -y @agentmemory/mcp

Diagnostics for Windows: if npx @agentmemory/agentmemory fails, re-run with --verbose to see the actual engine stderr. Common failure modes:

| Symptom | Fix | | --- | --- | | iii-engine process started then did not become ready within 15s | Engine crashed on startup — re-run with --verbose, check stderr | | Could not start iii-engine | Neither iii.exe nor Docker is installed. See Option A or B above | | Port conflict | netstat -ano \| findstr :3111 to see what's bound, then kill it or use --port <N> | | Docker fallback skipped even though Docker is installed | Make sure Docker Desktop is actually running (system tray icon) |

Note: there is no cargo install iii-engineiii is not published to crates.io. The only supported install methods are the prebuilt binary above, the upstream sh install script (macOS/Linux only), and the Docker image.


Every coding agent forgets everything when the session ends. You waste the first 5 minutes of every session re-explaining your stack. agentmemory runs in the background and eliminates that entirely.

Session 1: "Add auth to the API"
  Agent writes code, runs tests, fixes bugs
  agentmemory silently captures every tool use
  Session ends -> observations compressed into structured memory

Session 2: "Now add rate limiting"
  Agent already knows:
    - Auth uses JWT middleware in src/middleware/auth.ts
    - Tests in test/auth.test.ts cover token validation
    - You chose jose over jsonwebtoken for Edge compatibility
  Zero re-explaining. Starts working immediately.

vs built-in agent memory

Every AI coding agent ships with built-in memory — Claude Code has MEMORY.md, Cursor has notepads, Cline has memory bank. These work like sticky notes. agentmemory is the searchable database behind the sticky notes.

| | Built-in (CLAUDE.md) | agentmemory | | --- | --- | --- | | Scale | 200-line cap | Unlimited | | Search | Loads everything into context | BM25 + vector + graph (top-K only) | | Token cost | 22K+ at 240 observations | ~1,900 tokens (92% less) | | Cross-agent | Per-agent files | MCP + REST (any agent) | | Coordination | None | Leases, signals, actions, routines | | Observability | Read files manually | Real-time viewer on:3113 |


Memory Pipeline

PostToolUse hook fires
  -> SHA-256 dedup (5min window)
  -> Privacy filter (strip secrets, API keys)
  -> Store raw observation
  -> LLM compress -> structured facts + concepts + narrative
  -> Vector embedding (6 providers + local)
  -> Index in BM25 + vector

Stop / SessionEnd hook fires
  -> Summarize session
  -> Knowledge graph extraction (if GRAPH_EXTRACTION_ENABLED=true)
  -> Slot reflection (if SLOT_REFLECT_ENABLED=true)

SessionStart hook fires
  -> Load project profile (top concepts, files, patterns)
  -> Hybrid search (BM25 + vector + graph)
  -> Token budget (default: 2000 tokens)
  -> Inject into conversation

4-Tier Memory Consolidation

Inspired by how human brains process memory — not unlike sleep consolidation.

| Tier | What | Analogy | | --- | --- | --- | | Working | Raw observations from tool use | Short-term memory | | Episodic | Compressed session summaries | "What happened" | | Semantic | Extracted facts and patterns | "What I know" | | Procedural | Workflows and decision patterns | "How to do it" |

Memories decay over time (Ebbinghaus curve). Frequently accessed memories strengthen. Stale memories auto-evict. Contradictions are detected and resolved.

What Gets Captured

| Hook | Captures | | --- | --- | | SessionStart | Project path, session ID | | UserPromptSubmit | User prompts (privacy-filtered) | | PreToolUse | File access patterns + enriched context | | PostToolUse | Tool name, input, output | | PostToolUseFailure | Error context | | PreCompact | Re-injects memory before compaction | | SubagentStart/Stop | Sub-agent lifecycle | | Stop | End-of-session summary | | SessionEnd | Session complete marker |

Key Capabilities

| Capability | Description | | --- | --- | | Automatic capture | Every tool use recorded via hooks — zero manual effort | | Semantic search | BM25 + vector + knowledge graph with RRF fusion | | Memory evolution | Versioning, supersession, relationship graphs | | Auto-forgetting | TTL expiry, contradiction detection, importance eviction | | Privacy first | API keys, secrets, <private> tags stripped before storage | | Self-healing | Circuit breaker, provider fallback chain, health monitoring | | Claude bridge | Bi-directional sync with MEMORY.md | | Knowledge graph | Entity extraction + BFS traversal | | Team memory | Namespaced shared + private across team members | | Citation provenance | Trace any memory back to source observations | | Git snapshots | Version, rollback, and diff memory state |


Triple-stream retrieval combining three signals:

| Stream | What it does | When | | --- | --- | --- | | BM25 | Stemmed keyword matching with synonym expansion | Always on | | Vector | Cosine similarity over dense embeddings | Embedding provider configured | | Graph | Knowledge graph traversal via entity matching | Entities detected in query |

Fused with Reciprocal Rank Fusion (RRF, k=60) and session-diversified (max 3 results per session).

Embedding providers

agentmemory auto-detects your provider. For best results, install local embeddings (free):

npm install @xenova/transformers

| Provider | Model | Cost | Notes | | --- | --- | --- | --- | | Local (recommended) | all-MiniLM-L6-v2 | Free | Offline, +8pp recall over BM25-only | | Gemini | text-embedding-004 | Free tier | 1500 RPM | | OpenAI | text-embedding-3-small | $0.02/1M | Highest quality | | Voyage AI | voyage-code-3 | Paid | Optimized for code | | Cohere | embed-english-v3.0 | Free trial | General purpose | | OpenRouter | Any model | Varies | Multi-model proxy |


51 tools, 6 resources, 3 prompts, and 4 skills — the most comprehensive MCP memory toolkit for any agent.

50 Tools

Core tools (always available)

| Type | Name | Description | | --- | --- | --- | | Resource | agentmemory://status | Health, session count, memory count | | Resource | agentmemory://project/{name}/profile | Per-project intelligence | | Resource | agentmemory://memories/latest | Latest 10 active memories | | Resource | agentmemory://graph/stats | Knowledge graph statistics | | Prompt | recall_context | Search + return context messages | | Prompt | session_handoff | Handoff data between agents | | Prompt | detect_patterns | Analyze recurring patterns | | Skill | /recall | Search memory | | Skill | /remember | Save to long-term memory | | Skill | /session-history | Recent session summaries | | Skill | /forget | Delete observations/sessions |

Standalone MCP

Run without the full server — for any MCP client. Either of these works:

npx -y @agentmemory/agentmemory mcp   # canonical (always available)
npx -y @agentmemory/mcp                # shim package alias

Or add to your agent's MCP config:

Most agents (Cursor, Claude Desktop, Cline, etc.):

{
  "mcpServers": {
    "agentmemory": {
      "command": "npx",
      "args": ["-y", "@agentmemory/mcp"]
    }
  }
}

OpenCode (opencode.json):

{
  "mcp": {
    "agentmemory": {
      "type": "local",
      "command": ["npx", "-y", "@agentmemory/mcp"],
      "enabled": true
    }
  }
}

Auto-starts on port 3113. Live observation stream, session explorer, memory browser, knowledge graph visualization, and health dashboard.

open http://localhost:3113

The viewer server binds to 127.0.0.1 by default. The REST-served /agentmemory/viewer endpoint follows the normal AGENTMEMORY_SECRET bearer-token rules. CSP headers use a per-response script nonce and disable inline handler attributes (script-src-attr 'none').

iii console — trace-level engine inspection

agentmemory runs on the iii engine, so the official iii console gives you OpenTelemetry traces, the raw key/value state store, the stream monitor, and a direct function invoker for every piece of memory machinery. Use it to watch a memory.search call hit BM25 → embeddings → reranker in real time, replay a hook invocation, or poke individual functions without going through MCP.

iii console dashboard — system counters, application flow, registered triggers, live WebSocket status
Dashboard: functions, triggers, workers, streams, live flow graph. Screenshot from iii.dev/docs/console.

Install once:

curl -fsSL https://install.iii.dev/console/main/install.sh | sh

Launch alongside agentmemory:

# The agentmemory viewer already holds port 3113, so run the console on 3114.
iii-console --port 3114 --engine-port 3111 --ws-port 3112

Then open http://localhost:3114.

What you can do from the console:

| Page | Use it to | | --- | --- | | Functions | Invoke any of agentmemory's ~33 functions directly with a JSON payload — handy for testing memory.recall, memory.consolidate, graph.query without wiring a client. | | Triggers | Replay HTTP triggers (the agentmemory REST endpoints), fire the consolidation cron manually, or emit queue events. | | States | Browse the KV store — sessions, memory slots, lifecycle timers, embeddings index — and edit values in place. | | Streams | Watch live memory writes, hook events, and observation updates as they flow through iii's WebSocket stream. | | Traces | OpenTelemetry waterfall / flame / service-breakdown views. Filter by trace_id to see exactly which functions, DB calls, and embedding requests a single memory.search produced. | | Logs | Structured OTEL logs correlated to trace/span IDs. |

iii console trace waterfall view showing per-span duration
Traces: waterfall / flame / service breakdown for every memory operation.

Traces are already on:

iii-config.yaml ships with the iii-observability worker enabled (exporter: memory, sampling_ratio: 1.0, metrics + logs). No extra config needed — the moment agentmemory starts, every memory operation emits a trace span and a structured log the console can read.

If you want to export to Jaeger/Honeycomb/Grafana Tempo instead, change exporter: memory to exporter: otlp and set the collector endpoint per iii's observability docs.

Heads-up: no auth is enforced on the console itself — keep it bound to 127.0.0.1 (the default) and never expose it publicly.


LLM Providers

agentmemory auto-detects from your environment. No API key needed if you have a Claude subscription.

| Provider | Config | Notes | | --- | --- | --- | | No-op (default) | No config needed | LLM-backed compress/summarize is DISABLED. Synthetic BM25 compression + recall still work. See AGENTMEMORY_ALLOW_AGENT_SDK below if you used to rely on the Claude-subscription fallback. | | Anthropic API | ANTHROPIC_API_KEY | Per-token billing | | MiniMax | MINIMAX_API_KEY | Anthropic-compatible | | Gemini | GEMINI_API_KEY | Also enables embeddings | | OpenRouter | OPENROUTER_API_KEY | Any model | | Claude subscription fallback | AGENTMEMORY_ALLOW_AGENT_SDK=true | Opt-in only. Spawns @anthropic-ai/claude-agent-sdk sessions — used to cause unbounded Stop-hook recursion (#149 follow-up) so it is no longer the default. |
