Claude Code often lacks direct file access. This creates friction for developers. You do not need a heavy SDK to fix this.

Build a Model Context Protocol (MCP) server. Use only Python standard libraries. Use no pip installs. Use no frameworks.

You get:

• Zero dependencies.
• Full control of tools.
• Better security.
• No bloat.

This works for CI/CD pipelines. It works for Docker containers. It works anywhere you run Python 3.6 or newer.

The process is simple. Create a file called file_server.py. Use the json and sys libraries. Implement the JSON-RPC protocol over stdin and stdout.

Add the server to your claude.json configuration. Restart Claude Code. Your AI now reads and writes files directly.

Warning: This basic version lacks path sanitization. Add checks to restrict access to specific directories for production.

MCP is simple. You do not need to wait for others to build tools. Build exactly what you need. Keep your workflow lean.
