Improved examples

[E-Kuerschner]

Hello, thanks for the useful library! I want to return more than a string from one of my methods; ideally, an object that represents a user which the model could describe, but there are no examples around returning anything other than a string. It looks like JSON is supported by looking at the source code.

Hey — you can do this by just defining a method that returns an object — it's just TypeScript types:

type User = {
  id: number,
  email: string,
}

export class ExampleWorkerMCP extends WorkerEntrypoint<Env> {
  /**
   * Returns a user
   * @return {User} A user object
   * */
  async getUser(id: number): User {
    return {
      id,
      email: 'test@test.com',
    }
  }
}

If you're getting started building a new MCP server — we just added new docs and a revamped approach here:

hey @irvinebroque, thanks for writing back! I've tried several variations of the above but I keep running into something like this:

Below is the code from the associated method:

	/**
	 * Gets information about the host of the event
	 * @return {TestUser} The user object describing the host
	 */
	async getHostInfo() {
		return {
			name: "Erich",
			age: 32,
			location: "Berlin"
		};
	}

I'm thinking I could make a call to Claude via my personal API key within the worker, but I was under the impression that sending back the object directly from the worker would be enough for the client LLM to summarize.

I'm running into this exact issue as well.

I test this on Cursor and it didn't work either.
