Implementation Reference
- src/index.ts:709-728 (handler)Main handler function for the 'list_templates' tool. It checks input arguments for category or tags filters and calls the appropriate TemplateService method to retrieve templates, then returns them as JSON text content.
private async handleListTemplates(args: any) { let templates; if (args.category) { templates = templateService.getTemplatesByCategory(args.category); } else if (args.tags && args.tags.length > 0) { templates = templateService.getTemplatesByTags(args.tags); } else { templates = templateService.getAllTemplates(); } return { content: [ { type: 'text', text: JSON.stringify(templates, null, 2) } ] }; } - src/index.ts:200-210 (schema)Input schema for the list_templates tool, defining optional category (string) and tags (array of strings) parameters for filtering templates.
inputSchema: { type: 'object', properties: { category: { type: 'string', description: 'Filter by category' }, tags: { type: 'array', items: { type: 'string' }, description: 'Filter by tags' } } } - src/index.ts:197-211 (registration)Tool definition object registered in the 'tools' array, which is returned by the ListTools handler.
{ name: 'list_templates', description: 'List all message templates', inputSchema: { type: 'object', properties: { category: { type: 'string', description: 'Filter by category' }, tags: { type: 'array', items: { type: 'string' }, description: 'Filter by tags' } } } }, - src/index.ts:508-509 (registration)Switch case in the CallToolRequest handler that dispatches 'list_templates' calls to the specific handleListTemplates method.
case 'list_templates': return await this.handleListTemplates(args); - Core helper method in TemplateService that retrieves all templates from the internal map, used by the handler when no filters are specified.
