Setup

MCP Integration in Cursor

Add the following configuration to your ~/.cursor/mcp.json file or configure via the settings menu in Cursor.

{
    "mcpServers": {
        "usqlmcp": {
            "command": "usqlmcp",
            "args": ["--dsn", "sqlite3:///your/db/dsn/file.db"]
        }
    }
}

Other tools

{
    "servers": {
        "usqlmcp": {
            "type": "stdio",
            "command": "usqlmcp",
            "args": ["--dsn", "sqlite3:///your/db/dsn/file.db"]
        }
    }
}

Docker Usage

You can also run usqlmcp using Docker:

docker run -i --rm ghcr.io/thesoulless/usqlmcp:latest --dsn postgres://username:password@host.docker.internal:5432/dbname?sslmode=disable

Note: When connecting to a database on your host machine, use host.docker.internal instead of localhost or 127.0.0.1.

Example with SQLite and Volume Mounting

To use a SQLite database file from your local machine:

docker run -i --rm -v /path/to/local/mydatabase.db:/data/mydatabase.db ghcr.io/thesoulless/usqlmcp:latest --dsn sqlite3:///data/mydatabase.db

This mounts just your local SQLite database file directly into the container, providing access to only what's needed.
