Codebase Memory: MCP server, setup and security

What Codebase Memory does

According to its repository: “Indexes a repo into a persistent local knowledge graph of functions, classes, call chains, HTTP routes and cross-service links, using tree-sitter and LSP.”

An MCP server gives an AI agent extra tools it calls during the conversation: the agent reads their description, decides to use them and gets the result back. Codebase Memory is listed under Developer tools, a category of 475 servers in the directory, where it ranks #4 by stars.

Topics declared by the repository: claude-code, code-analysis, code-intelligence, developer-tools, knowledge-graph, sqlite.

Installing and connecting Codebase Memory

Distribution modes declared in the official MCP registry:

• npm package (Node.js, usually started with npx)
• PyPI package (Python, started with uvx or pip)
• MCPB bundle (one-click install in Claude Desktop)

Like any MCP server, you declare it in your client's configuration (Claude Desktop, Claude Code, Cursor, VS Code, Codex…): a name, the command that starts it or its URL, and any environment variables. The client then starts it and lists its tools. Project language: C/C++. Listed systems: macOS, Windows, Linux.

Security: what to check

An MCP server runs code with the rights you give it, and the model reads its tool descriptions: a malicious or compromised server can hijack the agent. Read the code, or pick a maintained and widely used server, before connecting it.

None of the risk signals we track (system access, secrets, missing licence, abandonment) applies to Codebase Memory. That does not replace reading the code.

Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.

Project activity and maintenance

Created on February 24, 2026, the DeusData/codebase-memory-mcp repository has 47,396 stars and 3,892 forks, with 486 open issues. It is one of the most starred servers in the directory. It received changes this month. Version published in the registry: 0.12.1 (October 17, 2026).

Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
