Implementation Reference

• index.ts:18-31 (handler)

  The asynchronous handler function for the 'sample-tool' that takes an input string, processes it by prefixing 'Processed: ', and returns it as text content.

  async ({ input }) => {
    // Process the input
    const output = `Processed: ${input}`;
    
    // Return the result
    return {
      content: [
        {
          type: "text",
          text: output,
        },
      ],
    };
  }

• index.ts:15-17 (schema)

  The input schema for the 'sample-tool' defined using Zod, specifying a single string input parameter.

  {
    input: z.string().describe("Input parameter for the sample tool"),
  },

• index.ts:12-32 (registration)

  The registration of the 'sample-tool' on the MCP server, including name, description, input schema, and handler function.

  server.tool(
    "sample-tool",
    "A sample tool for demonstration purposes",
    {
      input: z.string().describe("Input parameter for the sample tool"),
    },
    async ({ input }) => {
      // Process the input
      const output = `Processed: ${input}`;
      
      // Return the result
      return {
        content: [
          {
            type: "text",
            text: output,
          },
        ],
      };
    }
  );
