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

| Layer | What it does | Why it matters | |-------|--------------|----------------| | Memory model | Sessions, structured logs, notebooks, summaries, and semantic memories | Keeps project history searchable instead of trapped in one chat | | Scale layer | SQLite WAL mode, connection pooling, serialized write queue, and HTTP rate-limit presets | Lets one server support solo use, multi-agent work, and swarm-style bursts | | Intelligence layer | FTS filter, semantic re-rank, bounded semantic fallback, auto-classification, write-time consolidation, and compaction candidates | Keeps recall useful as memory grows instead of letting duplicates pile up | | Token layer | Lightweight 7-tool surface, semantic re-rank before retrieval, and write-time deduplication | Reduces tokens sent to the model on every recall and cost stays predictable as memory scales | | Deployment layer | Pip, Docker, STDIO, HTTP, --swarm, --swarm-max, and --trusted | Lets you run private local memory or shared multi-agent memory with the same MCP surface |

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.

npx degit Lyellr88/MARM-Systems/skills

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.

Local pip HTTP (zero config)

"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

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 ```

</details>

<details> <summary><strong>Local Python swarm modes (HTTP & STDIO)</strong></summary>

Local Python swarm modes (HTTP & 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

</details>

<details> <summary><strong>Docker HTTP (key required)</strong></summary>

Docker HTTP (key required)

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

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.

| What it gives you | How it works | |-------------------|-------------| | Browse/search/edit all memories | Direct SQLite, no MCP required | | Manage sessions and protocol logs | Runs on port :8002 alongside MCP on :8001 | | Notebook CRUD with inline editor | Same auth model (MARM_API_KEY) as the MCP server | | Delete-all with count confirmation | Docker image included; WAL mode handles concurrent access | | View the write queue in real time | Pulls live data from the write queue |

# 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

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.

| Category | Tool | Description | |--------------|----------|-----------------| | Memory Intelligence | marm_smart_recall | Hybrid recall with FTS5 filtering, semantic reranking, bounded fallback search, and chunk-aware scoring for long memories. Supports search_all=True, project/platform filters, and detail=1/2/3 depth controls | | Logging System | marm_log_entry | Add structured session log entries. Session/topic routing, summary-cache invalidation, and context summary preparation are handled by the server | | | marm_log_show | Display all entries and sessions (filterable) | | | marm_delete | Delete a log session, log entry, or notebook entry (type="log"\|"notebook") | | Reasoning & Workflow | marm_summary | Generate cached session summaries with intelligent truncation for LLM conversations | | Notebook Management | marm_notebook | Unified notebook tool: add, use, show, status, or clear entries with action="add"\|"use"\|"show"\|"status"\|"clear" | | Memory Maintenance | marm_compaction | Unified compaction workflow with action="status"\|"candidates"\|"review"\|"stage"\|"apply"\|"discard" for agent-assisted memory cleanup |

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, 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

| Session Size ($N$) | Min Latency | Median Latency | p95 Latency | | :--- | :--- | :--- | :--- | | N = 100 | 12.0 ms | 17.4 ms | 20.8 ms | | N = 500 | 12.4 ms | 20.5 ms | 22.6 ms | | N = 1,000 | 15.9 ms | 23.3 ms | 25.1 ms | | N = 4,000 | 23.1 ms | 30.4 ms | 31.3 ms |

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
