Using the MCP Inspector for Debugging

The MCP Inspector helps with debugging your MCP server by providing a visual interface to test your methods:

pnpm inspector

This will start the MCP Inspector which you can access in your browser. It allows you to:

• See all available methods
• Test methods with different parameters
• View the response data
• Debug issues with your MCP server
