 The above commands will automatically configure your AI tool to use the MCP server by editing the appropriate configuration file, but you can also manually edit the appropriate configuration file:
 - **Claude Desktop:** `~/Library/Application Support/Claude/claude_desktop_config.json`
 - **Cursor:** `~/.cursor/mcp.json`
 - **Windsurf:** `~/.codeium/windsurf/mcp_config.json`
