Implementation Reference
- src/index.ts:1046-1086 (handler)The main handler function for the 'update_metadata' tool. Reads current task data from config file, conditionally updates metadata fields (tags, priority, estimated_completion_time) based on input arguments, persists changes by calling writeTaskData, and returns a standardized MCP response with success or error message.
private async updateMetadata(args: any): Promise<any> { try { const taskData = await this.readTaskData(); // Update the metadata if (args.tags !== undefined) { taskData.metadata.tags = args.tags; } if (args.priority !== undefined) { taskData.metadata.priority = args.priority; } if (args.estimated_completion_time !== undefined) { taskData.metadata.estimated_completion_time = args.estimated_completion_time; } // Write the updated task data to the file await this.writeTaskData(taskData); return { content: [ { type: 'text', text: 'Metadata updated successfully.', }, ], }; } catch (error) { console.error('Error updating metadata:', error); return { content: [ { type: 'text', text: `Error updating metadata: ${error instanceof Error ? error.message : String(error)}`, }, ], isError: true, }; } } - src/index.ts:360-384 (registration)Tool registration in the ListToolsRequestSchema handler. Defines the tool name, description, and inputSchema which validates optional updates to tags (array of strings), priority (enum: high/medium/low), and estimated_completion_time (string).
{ name: 'update_metadata', description: 'Updates the task metadata.', inputSchema: { type: 'object', properties: { tags: { type: 'array', items: { type: 'string' }, description: 'Tags to categorize the task' }, priority: { type: 'string', enum: ['high', 'medium', 'low'], description: 'Priority level of the task' }, estimated_completion_time: { type: 'string', description: 'Estimated completion time (ISO timestamp or duration)' } } } }, - src/index.ts:446-447 (registration)Routing case in the CallToolRequestSchema switch statement that dispatches 'update_metadata' calls to the private updateMetadata handler method.
