Implementation Reference

• src/index.ts:123-146 (handler)

  The update_todo tool is registered and implemented directly in src/index.ts, taking todo_id and title as arguments and calling the backend via makeRequest.

  mcp.tool(
    "update_todo",
    "Update the title of an existing todo item.",
    {
      todo_id: z.string().describe("UUID of the todo item"),
      title: z.string().describe("New title for the todo item"),
    },
    async ({ todo_id, title }) => {
      try {
        const todo = await makeRequest<Todo>(
          "PUT",
          `/api/todos/${todo_id}`,
          { title }
        );
        return {
          content: [{ type: "text", text: `Updated todo: ${formatTodo(todo)}` }],
        };
      } catch (e: unknown) {
        if ((e as NodeJS.ErrnoException).code === "404")
          return { content: [{ type: "text", text: "Todo not found." }] };
        throw e;
      }
    }
  );
