# CodeQL MCP Server
This project runs a Model Context Protocol (MCP) server that wraps the CodeQL query server. It enables tools like [Cursor](https://cursor.sh/) 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`](https://github.com/astral-sh/uv):
```bash
uv pip install -r requirements.txt
```
or with `pip`:
```bash
pip install fastmcp httpx
```
## Running the MCP Server
```bash
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.
