Implementation Reference
- src/index.ts:374-385 (handler)MCP CallToolRequest handler implementation for the 'get_user_comments' tool. Parses arguments using Zod schema, calls RedditClient.getUserComments, and formats response as JSON text.
case 'get_user_comments': { const args = GetUserCommentsSchema.parse(request.params.arguments); const comments = await redditClient.getUserComments(args.username, args.sort, args.limit); return { content: [ { type: 'text', text: JSON.stringify(comments, null, 2), }, ], }; } - src/index.ts:67-71 (schema)Zod schema for validating input parameters of the get_user_comments tool: username (required string), sort (enum: hot/new/top, default 'new'), limit (1-100, default 25).
const GetUserCommentsSchema = z.object({ username: z.string().min(1, "Username is required"), sort: z.enum(['hot', 'new', 'top']).default('new'), limit: z.number().min(1).max(100).default(25), }); - src/index.ts:205-231 (registration)Tool registration in ListToolsResponse: defines name, description, and inputSchema matching the Zod schema.
