Implementation Reference

• src/index.ts:129-150 (handler)

  Inline handler function for the 'set-prioity' MCP tool. It calls the helper function setTaskPriority and formats success/error responses.

  async (params) => {
    try {
      await mongooseUtils.setTaskPriority(params.task_id, params.new_priority);
      return {
        content: [
          {
            type: "text",
            text: `Set task "${params.task_id}" Priority to "${params.new_priority}" successfully!`,
          },
        ],
      };
    } catch {
      return {
        content: [
          {
            type: "text",
            text: `Failed to set task "${params.task_id}" priority to "${params.new_priority}".`,
          },
        ],
      };
    }
  }

• src/index.ts:119-121 (schema)

  Zod input schema for the 'set-prioity' tool defining task_id and new_priority parameters.

    task_id: z.string(),
    new_priority: z.enum(["low", "medium", "high"]),
  },

• src/index.ts:115-151 (registration)

  Registration of the 'set-prioity' tool using server.tool, including name, description, schema, hints, and handler.

  server.tool(
    "set-prioity",
    "set a task to a different priority",
    {
      task_id: z.string(),
      new_priority: z.enum(["low", "medium", "high"]),
    },
    {
      title: "set a task to a different priority",
      readonlyHint: false,
      destructiveHint: false,
      idempotentHint: false,
      openWorldHint: true,
    },
    async (params) => {
      try {
        await mongooseUtils.setTaskPriority(params.task_id, params.new_priority);
        return {
          content: [
            {
              type: "text",
              text: `Set task "${params.task_id}" Priority to "${params.new_priority}" successfully!`,
            },
          ],
        };
      } catch {
        return {
          content: [
            {
              type: "text",
              text: `Failed to set task "${params.task_id}" priority to "${params.new_priority}".`,
            },
          ],
        };
      }
    }
  );

• src/utils/mongoose.ts:121-136 (helper)

  Helper function that performs the actual database update for task priority using Mongoose Task model.

  export async function setTaskPriority(
    taskId: string,
    priority: "low" | "medium" | "high"
  ) {
    try {
      const task = await Task.findById(taskId);
      if (!task) {
        throw new Error("Task not found");
      }
  
      task.priority = priority;
      await task.save();
    } catch {
      throw new Error("Failed to set priority");
    }
  }
