Check the Tools page in Smithery to inspect and test each one of them.

Development

Install dependencies:

npm install

Build the server:

npm run build

For development with auto-rebuild:

npm run watch

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a package script:

npm run inspector

To generate an updated build and inspect:

npm run build-and-inspect

The Inspector will provide a URL to access debugging tools in your browser.
