Codebase Memory MCP Server

The fastest and most efficient code intelligence engine for AI coding agents. Full-indexes an average repository in milliseconds, the Linux kernel (28M LOC, 75K files) in 3 minutes. Answers structural queries in under 1ms. Ships as a native executable with a small verified runtime-asset set for macOS, Linux, and Windows - download, run install, done.

People who work with code analysis, developer tools and knowledge graph and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in C.

01 · Install Codebase Memory

before you install - you'll need

The README does not document required environment variables for a basic install.

Claude Code

claude mcp add deusdata-codebase-memory-mcp -- npx -y codebase-memory-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "deusdata-codebase-memory-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "codebase-memory-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions · Claude Desktop extension (.mcpb bundle)

license MIT - declared in the repository

npm package codebase-memory-mcp - unscoped; check the name against the project README before installing

registry namespace io.github.DeusData is GitHub-verified and matches the repo owner
