Implementation Reference

• src/index.ts:1437-1451 (handler)

  The handler logic for the 'todoist_delete_project' tool. Validates input using isProjectIdArgs type guard, calls todoistClient.deleteProject(projectId), and returns a success message.

  if (name === "todoist_delete_project") {
    if (!isProjectIdArgs(args)) {
      throw new Error("Invalid arguments for todoist_delete_project");
    }
  
    await todoistClient.deleteProject(args.projectId);
    
    return {
      content: [{ 
        type: "text", 
        text: `Project ${args.projectId} deleted successfully` 
      }],
      isError: false,
    };
  }

• src/index.ts:462-475 (schema)

  The Tool object definition specifying the name, description, and input schema (requiring projectId) for the todoist_delete_project tool.

  const DELETE_PROJECT_TOOL: Tool = {
    name: "todoist_delete_project",
    description: "Delete a project by its ID",
    inputSchema: {
      type: "object",
      properties: {
        projectId: {
          type: "string",
          description: "The ID of the project to delete"
        }
      },
      required: ["projectId"]
    }
  };

• src/index.ts:1083-1121 (registration)

  Registration of the todoist_delete_project tool (as DELETE_PROJECT_TOOL) in the list of tools returned by the ListToolsRequestSchema handler.

  server.setRequestHandler(ListToolsRequestSchema, async () => ({
    tools: [
      // Task tools
      CREATE_TASK_TOOL,
      QUICK_ADD_TASK_TOOL,
      GET_TASKS_TOOL,
      GET_TASK_TOOL,
      UPDATE_TASK_TOOL,
      DELETE_TASK_TOOL,
      COMPLETE_TASK_TOOL,
      REOPEN_TASK_TOOL,
      SEARCH_TASKS_TOOL,
      MOVE_TASK_TOOL,
      BULK_MOVE_TASKS_TOOL,
      // Project tools
      GET_PROJECTS_TOOL,
      GET_PROJECT_TOOL,
      CREATE_PROJECT_TOOL,
      UPDATE_PROJECT_TOOL,
      DELETE_PROJECT_TOOL,
      // Section tools
      GET_SECTIONS_TOOL,
      CREATE_SECTION_TOOL,
      UPDATE_SECTION_TOOL,
      DELETE_SECTION_TOOL,
      // Label tools
      CREATE_LABEL_TOOL,
      GET_LABEL_TOOL,
      GET_LABELS_TOOL,
      UPDATE_LABEL_TOOL,
      DELETE_LABEL_TOOL,
      // Comment tools
      CREATE_COMMENT_TOOL,
      GET_COMMENT_TOOL,
      GET_COMMENTS_TOOL,
      UPDATE_COMMENT_TOOL,
      DELETE_COMMENT_TOOL,
    ],
  }));

• src/index.ts:823-832 (helper)

  Type guard helper function isProjectIdArgs used to validate the input arguments for project-related tools, including todoist_delete_project.

  function isProjectIdArgs(args: unknown): args is {
    projectId: string;
  } {
    return (
      typeof args === "object" &&
      args !== null &&
      "projectId" in args &&
      typeof (args as { projectId: string }).projectId === "string"
    );
  }
