DB Conn MCP

A dead-simple, self-hosted Model Context Protocol (MCP) server for querying your databases with AI agents (Claude, Cursor, Windsurf, VS Code, Zed, Codex, and more). It runs locally over stdio via the published package.

People connecting database tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

Claude Code

claude mcp add idle-sync-db-conn-mcp -- uvx db-conn-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "idle-sync-db-conn-mcp": {
      "command": "uvx",
      "args": [
        "db-conn-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
