Implementation Reference

• src/server.ts:20-24 (handler)

  The handler function that executes the 'hello' tool logic. Takes a 'name' parameter and returns a greeting message in MCP content format.

  async ({ name }) => {
    return {
      content: [{ type: 'text' as const, text: `Hello, ${name}!` }],
    }
  }

• src/server.ts:17-19 (schema)

  Zod schema definition for the 'hello' tool input. Defines a 'name' parameter as a string with a description.

  {
    name: z.string().describe('Name to greet'),
  },

• src/server.ts:14-25 (registration)

  Tool registration with the MCP server using server.tool(). Registers 'hello' tool with its name, description, schema, and handler function.

  server.tool(
    'hello',
    'A simple greeting tool that returns a hello message.',
    {
      name: z.string().describe('Name to greet'),
    },
    async ({ name }) => {
      return {
        content: [{ type: 'text' as const, text: `Hello, ${name}!` }],
      }
    }
  )
