Adding New Tools

To add a new tool, modify src/server.ts:

server.tool(
  "tool-name",
  "Tool description",
  {
    // Define your parameters using Zod schemas
    param: z.string().describe("Parameter description"),
  },
  async ({ param }): Promise<CallToolResult> => {
    // Your tool implementation
    return {
      content: [
        {
          type: "text",
          text: `Result: ${param}`,
        },
      ],
    };
  },
);

Adding New Prompts

To add a new prompt template, modify src/server.ts:

server.prompt(
  "prompt-name",
  "Prompt description",
  {
    // Define your parameters using Zod schemas
    param: z.string().describe("Parameter description"),
  },
  async ({ param }): Promise<GetPromptResult> => {
    return {
      messages: [
        {
          role: "user",
          content: {
            type: "text",
            text: `Your prompt content with ${param}`,
          },
        },
      ],
    };
  },
);
