A Model Context Protocol (MCP) server that wraps the CodeQL query server

CodeQL MCP Server

This project runs a Model Context Protocol (MCP) server that wraps the CodeQL query server. It enables tools like Cursor or AI agents to interact with CodeQL through structured commands and doc search.

---

Features

• ✅ Register CodeQL databases
• ✅ Run full queries or quick-evaluate a symbol
• ✅ Decode .bqrs files into JSON
• ✅ Locate predicate/class symbol positions

---

File Structure

File	Purpose
server.py	Main FastMCP server exposing CodeQL tools
codeqlclient.py	CodeQLQueryServer implementation (JSON-RPC handler)

---

Requirements

Install with uv:

uv pip install -r requirements.txt

or with pip:

pip install fastmcp httpx

Running the MCP Server

uv run mcp run server.py -t sse

• Starts the server at http://localhost:8000/sse
• Required for Cursor or AI agent use

Cursor Config

Make sure your .cusor/config.json contains:

{
  "mcpServers": {
    "CodeQL": {
      "url": "http://localhost:8000/sse"
    }
  }
}

Notes

• Tools like Cursor will invoke these commands directly via natural language.
• You must have a codeql binary in your $PATH, or hardcode its path in codeqlclient.py.
• You should probably specify query locations, query write locations and database paths in your prompts.
