MCP Inspector

The MCP inspector is a developer tool for testing and debugging MCP servers.

Getting started

This repository depends on the MCP TypeScript SDK. Until these repositories are made public and published to npm, the SDK has to be preinstalled manually:

Download the latest release of the SDK (the file named something like modelcontextprotocol-sdk-0.1.0.tgz). You don't need to extract it.
From within your checkout of this repository, run npm install --save path/to/sdk.tgz. This will overwrite the expected location for the SDK to allow you to proceed.

Then, you should be able to install the rest of the dependencies normally:

npm install

You can run it in dev mode via:

npm run dev

This will start both the client and server.

To run in production mode:

npm run build
npm start
