What is mem0-mcp CLAUDE.md?

A small MCP server that connects Claude Desktop or Claude Code to a self-hosted Mem0 memory service. Mem0 is a service for storing and retrieving information for AI assistants; this server uses a privately hosted instance rather than Mem0's cloud API.

Use it to run the mem0-mcp command and test operations such as listing memories for a user through a configured Mem0 instance.

It lets these clients use a self-hosted memory system when the official integrations only support Mem0's cloud service.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mem0-mcp CLAUDE.md scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

What this is

A single-tool-module MCP server (src/mem0_mcp/server.py) that wraps a self-hosted mem0 REST API as tools for Claude Desktop / Claude Code. Mem0's official MCP integrations only target Mem0's cloud API (different auth header, different routes), so this exists to talk to a self-hosted instance instead (see the sibling ../server-compose-files/ai-containers repo for that deployment).

Packaged as an installable console script (mem0-mcp, via [project.scripts] in pyproject.toml) rather than a loose script, so it can be run the way most MCP servers are — uvx --from git+<repo-url> mem0-mcp without cloning, or uv run --directory <path> mem0-mcp from a local clone.

Commands

uv sync                      # install dependencies into .venv
uv run mem0-mcp               # run the MCP server directly (stdio transport)

# Manual smoke test against a running mem0 instance:
MEM0_API_URL=http://dockerhost.home:8888 MEM0_API_KEY=m0sk_... uv run python -c "
from mem0_mcp.server import list_memories
print(list_memories(user_id='alice'))
"

There is no test suite, linter, or build step configured — verification is the manual smoke test above, or exercising the tools through Claude Desktop/Code directly.

Required env vars (server raises RuntimeError at import time if missing):

MEM0_API_URL — base URL of the self-hosted mem0 API
MEM0_API_KEY — an m0sk_... key from the mem0 dashboard

Optional env vars: MEM0_DEFAULT_USER_ID, MEM0_DEFAULT_AGENT_ID (see scoping rules below).

Architecture

Everything lives in src/mem0_mcp/server.py: an httpx.Client configured with the mem0 API's X-API-Key auth, wrapped by FastMCP tool functions that each map 1:1 to a mem0 REST endpoint (add_memory → POST /memories, search_memories → POST /search, etc.). Bulk-delete endpoints (delete_all_memories, /reset) are intentionally not exposed as tools, to keep the blast radius of an LLM-driven tool call small — use curl directly against the API for those.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
