This project allows you to run a Model Context Protocol (MCP) server that wraps the CodeQL query server, enabling tools like Cursor or AI agents to interact with CodeQL through structured commands and document search capabilities.
You'll need to install the required dependencies using either uv
or pip
:
Using uv
:
uv pip install -r requirements.txt
Or using pip
:
pip install fastmcp httpx
codeqlclient.py
Start the MCP server with the following command:
uv run mcp run server.py -t sse
This will:
To enable Cursor to work with your CodeQL MCP server, add the following to your .cursor/config.json
file:
{
"mcpServers": {
"CodeQL": {
"url": "http://localhost:8000/sse"
}
}
}
The MCP server supports several key features:
.bqrs
files into JSON formatWhen working with AI tools like Cursor:
To add this MCP server to Claude Code, run this command in your terminal:
claude mcp add-json "CodeQL" '{"url":"http://localhost:8000/sse"}'
See the official Claude Code MCP documentation for more details.
There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json
file so that it is available in all of your projects.
If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json
file.
To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".
When you click that button the ~/.cursor/mcp.json
file will be opened and you can add your server like this:
{
"mcpServers": {
"CodeQL": {
"url": "http://localhost:8000/sse"
}
}
}
To add an MCP server to a project you can create a new .cursor/mcp.json
file or add it to the existing one. This will look exactly the same as the global MCP server example above.
Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.
The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.
You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.
To add this MCP server to Claude Desktop:
1. Find your configuration file:
~/Library/Application Support/Claude/claude_desktop_config.json
%APPDATA%\Claude\claude_desktop_config.json
~/.config/Claude/claude_desktop_config.json
2. Add this to your configuration file:
{
"mcpServers": {
"CodeQL": {
"url": "http://localhost:8000/sse"
}
}
}
3. Restart Claude Desktop for the changes to take effect
