Adding New MCP Servers

1. Create Server Class:

// src/servers/my-server.ts
import { WorkerEntrypoint } from 'cloudflare:workers';
import type { Env } from '../types';

export class MyMCPServer extends WorkerEntrypoint<Env> {
  /**
   * Description of what this method does
   * @param param1 Parameter description
   * @returns What it returns
   */
  async myTool(param1: string) {
    return { result: `Hello ${param1}` };
  }
}

2. Register Routes:

// src/router.ts
app.all('/mcp/my-server/*', async (c) => {
  const server = new MyMCPServer(c.executionCtx, c.env);
  const proxy = new ProxyToSelf(server);
  return proxy.fetch(c.req.raw);
});

3. Update Health Check:

// Add to servers array in router.ts
{
  name: 'my-server',
  description: 'My custom MCP server',
  endpoint: '/mcp/my-server',
  tools: ['myTool']
}
