Implementation Reference

• src/index.ts:1379-1394 (handler)

  Handler implementation that validates arguments using isProjectIdArgs, calls todoistClient.getProject(projectId), formats the project using formatProject, and returns the details.

  if (name === "todoist_get_project") {
    if (!isProjectIdArgs(args)) {
      throw new Error("Invalid arguments for todoist_get_project");
    }
  
    const project = await todoistClient.getProject(args.projectId);
    return {
      content: [{ 
        type: "text", 
        text: `Project details:\nID: ${project.id}\n${formatProject(project)}` 
      }],
      isError: false,
    };
  }
  
  if (name === "todoist_create_project") {

• src/index.ts:383-396 (schema)

  Tool schema defining the name, description, and input schema requiring projectId.

  const GET_PROJECT_TOOL: Tool = {
    name: "todoist_get_project",
    description: "Get a specific project by its ID",
    inputSchema: {
      type: "object",
      properties: {
        projectId: {
          type: "string",
          description: "The ID of the project to retrieve"
        }
      },
      required: ["projectId"]
    }
  };

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

  Registration of all tools including todoist_get_project (as GET_PROJECT_TOOL) in 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:722-724 (helper)

  Helper function formatProject used to format the project details in the tool response.

  function formatProject(project: any): string {
    return `- ${project.name}${project.color ? `\n  Color: ${project.color}` : ''}${project.isFavorite ? `\n  Favorite: Yes` : ''}${project.viewStyle ? `\n  View: ${project.viewStyle}` : ''}${project.parentId ? `\n  Parent: ${project.parentId}` : ''}${project.id ? ` (ID: ${project.id})` : ''}`;
  }

• src/index.ts:823-832 (helper)

  Type guard function isProjectIdArgs used in the handler to validate input arguments.

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