Why MARM MCP: The Problem & Solution

Your AI forgets everything. MARM MCP doesn't.

MARM MCP is a local memory infrastructure layer for AI agents. It gives Claude, Codex, Gemini, Qwen, IDE agents, and other MCP clients one persistent place to store decisions, retrieve context, reuse notebooks, and keep long-running work from drifting.

The point is not "more tools." MARM exposes 7 focused MCP tools and moves the heavy work behind the server: session routing, protocol delivery, hybrid recall, serialized writes, rate-limit presets, write-time consolidation, and agent-assisted compaction. Because the tool surface stays small, re-ranking filters results before they reach the model, and consolidation catches duplicates at write time, token spend stays low and predictable as workloads grow.

How It Works

See Performance & Scaling Benchmarks for retrieval latency, concurrency, and write-cost numbers.

MARM gives AI agents persistent local memory, shared context, write-queue safety, swarm presets, and hybrid recall so commands, config keys, and project meaning all stay reachable.

Start Now

Recommended: guided setup with marm-init

The easiest way to install MARM is to let your agent do the setup with you. marm-init turns the usual MCP setup mess into one guided conversation: Python or Docker, HTTP or STDIO, local or remote server, API keys, config paths, dashboard startup, and multi-agent linking for Claude, Codex, Gemini, Qwen, Cursor, VS Code, and other MCP clients. No hunting through install docs, no guessing which config file your client uses, and no rewriting the same connection by hand for every agent.

Then tell your agent: "Use the marm-init skill to set up MARM."

Manual pip install

pip install marm-mcp-server

🚀 Quick Start for MCP (HTTP & STDIO)

Use this quick rule of thumb to choose your setup

• Local HTTP/STDIO = fastest single-machine setup.
• Docker HTTP = shared/always-on server (key required).
• Docker STDIO = private containerized local use (no HTTP key).

Swarm / multi-agent note: The write queue is enabled by default to serialize memory writes through one worker. For shared HTTP deployments, use --swarm (200 RPM) or --swarm-max (600 RPM) when starting the server. --trusted disables rate limiting entirely for private deployments. STDIO is still best for private single-agent/local use. See MCP-HANDBOOK.md for more info.

"agent" refers to claude, gemini, grok, qwen, or any MCP client. Codex uses --url instead of --transport to add MCP tools.

pip install marm-mcp-server
python -m marm_mcp_server
# Stuck on client setup? Open a Q&A thread: https://github.com/Lyellr88/MARM-Systems/discussions
# most agents use this --transport command
"agent" mcp add --transport http marm-memory http://localhost:8001/mcp
codex mcp add marm-memory --url http://localhost:8001/mcp

</details>

<summary><strong>Local pip STDIO</strong></summary>

#### Local pip STDIO

```bash
pip install marm-mcp-server
python -m marm_mcp_server.server_stdio
# most agents use this --transport command
"agent" mcp add --transport stdio marm-memory-stdio marm-mcp-stdio
codex mcp add marm-memory-stdio -- marm-mcp-stdio

Use HTTP when multiple agents need to share one live MARM server. STDIO is still best for private single-agent use because each client owns its own local process.

# HTTP shared server, normal multi-agent use
python -m marm_mcp_server --swarm

# HTTP shared server, heavier private swarm
python -m marm_mcp_server --swarm-max

# HTTP trusted private lab/server, rate limiting disabled
python -m marm_mcp_server --trusted

# STDIO remains keyless/private and does not use swarm flags
marm-mcp-stdio

Docker HTTP requires an API key because it exposes MARM as a network server; STDIO stays local to the client process and does not need one.

# Step 1: generate key (do not add < > around the key)
docker run --rm lyellr88/marm-mcp-server:latest --generate-key

# Step 2: run server
docker pull lyellr88/marm-mcp-server:latest
docker run -d --name marm-mcp-server \
  -p 127.0.0.1:8001:8001 \
  -e SERVER_HOST=0.0.0.0 \
  -e MARM_API_KEY=your-generated-key \
  -v ~/.marm:/home/marm/.marm \
  lyellr88/marm-mcp-server:latest

# Step 3: connect client
"agent" mcp add --transport http marm-memory http://localhost:8001/mcp --header "Authorization: Bearer your-generated-key"
codex mcp add marm-memory --url http://localhost:8001/mcp --bearer-token-env-var MARM_API_KEY

# --swarm: write queue on, 200 RPM - recommended for multi-agent shared servers
docker run -d --name marm-mcp-server \
  -p 127.0.0.1:8001:8001 \
  -e SERVER_HOST=0.0.0.0 \
  -e MARM_API_KEY=your-generated-key \
  -v ~/.marm:/home/marm/.marm \
  lyellr88/marm-mcp-server:latest --swarm

docker run --rm -i \
  -v ~/.marm:/home/marm/.marm \
  --entrypoint python \
  lyellr88/marm-mcp-server:latest \
  -m marm_mcp_server.server_stdio

• Docker HTTP requires a key; Docker STDIO does not.
• If you get 401, verify key match and client restart after env var changes.
• For full key setup, rotation, and troubleshooting: INSTALL-DOCKER.md

Claude Code remains the recommended first setup path, but MARM also works with other MCP clients and IDE agents.

CLI clients - Claude Code · Codex · Gemini CLI · Qwen CLI · Linux variants · Docker/key

IDE agents - VS Code / Copilot Agent · Cursor · Docker/key IDE setup

Remote/API platforms - xAI / Grok Remote MCP · Platform integration

Using a client that isn't listed? Open an issue and let us know; client adapters are a first-class feature request.

MARM Dashboard

A local web UI for browsing and managing your MARM memory; separate from the MCP server, reads and writes the same ~/.marm/marm_memory.db.

# Quick start (pip)
cd marm-dashboard
pip install -e .
python -m marm_dashboard --open

# Docker (same key and volume as MCP)
docker build -t marm-dashboard:local ./marm-dashboard
docker run --rm -p 127.0.0.1:8002:8002 \
  -e MARM_API_KEY=your-key \
  -v ~/.marm:/home/marm/.marm \
  marm-dashboard:local

See marm-dashboard/README.md for the full guide.

Complete MCP Tool Suite (7 Tools)

💡 Pro Tip: You don't need to manually call these tools! Just tell your AI agent what you want in natural language:

• "Claude, log this session as 'Project Alpha' and add this conversation as 'database design discussion'"
• "Remember this code snippet in your notebook for later"
• "Search for what we discussed about authentication yesterday"

The AI agent will automatically use the appropriate tools. Manual tool access is available for power users who want direct control.

A Deeper Look

MARM keeps MCP discovery lean with 7 tools by grouping domain operations behind explicit parameters like marm_notebook(action=...), marm_delete(type=...), and marm_compaction(action=...). Behind those tools, the server handles lifecycle setup, protocol refresh, docs indexing, date context, summary-cache maintenance, write queue handling, project/platform attribution, and health checks.

Under the hood, MARM uses SQLite WAL mode, connection pooling, serialized writes, HTTP swarm presets, safe local defaults, exact-query routing for syntax-heavy lookups, FTS→semantic reranking, bounded fallback search, chunk-aware long-memory recall, and summary/context/full recall depths to keep memory fast, stable, and token-efficient as projects grow.

For a deeper look into the MCP behavior, tool parameters, automation, and workflows, see MCP-HANDBOOK.md and FAQ.md.

Performance & Scaling Benchmarks

MARM is tuned for fast recall first, even as memory grows and multiple agents hit the same server.

1. Retrieval Latency Scaling

2. Multi-Agent Concurrency

• Parallel recall wins: 10 concurrent recalls completed in 316.3ms vs 647.0ms serial, a 51% time reduction.

3. Write-Time Ingestion Cost

• Write-time tradeoff: consolidation raises median ingest from 20.3ms to 85.2ms (4.2x) so dedupe/clustering cost stays off the hot recall path.

Benchmarks used a real SQLite database and the live all-MiniLM-L6-v2 encoder on local hardware. Reproduce them: marm-mcp-server/scripts/bench_hotpath.py
