Use it when modifying, reviewing, or extending the Mem0 MCP server described by the file.
Why use it?
It gives the coding agent repository-specific instructions so it can work with the project’s architecture and conventions.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions Claude Code.

This is Mocha-s/mem0_mcp_server's own configuration. It tells Claude Code how to work on mem0_mcp_server itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mem0_mcp_server configures →

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_server 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 6d 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.

Project Overview

This is a Mem0 MCP Server - a TypeScript implementation of a Model Context Protocol (MCP) server that provides intelligent memory management services. The server acts as a bridge between MCP clients (like Claude Desktop) and the Mem0 API, offering 6 core memory management tools with support for both stdio and HTTP transport modes.

Key Components

  • Main Entry Point (src/index.ts): Handles MCP server setup, tool registration, and transport layer management
  • Configuration (src/config/index.ts): Centralized config management using environment variables
  • Mem0 API Client (src/client/mem0-api.ts): HTTP client for Mem0 API with retry logic and proper error handling
  • Memory Tools (src/tools/index.ts): Implementation of 6 memory management tools with validation and batch operations

Development Commands

Essential Commands

  • npm run build - Compile TypeScript to JavaScript
  • npm run dev - Development mode with auto-reload using tsx
  • npm start - Run in stdio mode
  • npm run start:http - Run HTTP server on localhost
  • npm run start:http:external - Run HTTP server accessible from network (0.0.0.0:8081)

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.
