Implementation Reference

• src/index.ts:498-523 (handler)

  Full tool registration and inline handler implementation. Defines input schema with Zod, handles arguments, makes authenticated HTTPS POST request to AnySite API endpoint /api/linkedin/post/comments, returns JSON response or formatted error.
  server.tool( "get_linkedin_post_comments", "Get LinkedIn post comments", { urn: z.string().describe("Post URN"), count: z.number().default(10).describe("Max comments"), timeout: z.number().default(300).describe("Timeout in seconds"), sort: z.string().default("relevance").describe("Sort order") }, async ({ urn, count, timeout, sort }) => { const requestData = { timeout, urn, sort, count }; log(`Starting LinkedIn post comments lookup for: ${urn}`); try { const response = await makeRequest(API_CONFIG.ENDPOINTS.LINKEDIN_POST_COMMENTS, requestData); return { content: [{ type: "text", text: JSON.stringify(response, null, 2) }] }; } catch (error) { log("LinkedIn post comments lookup error:", error); return { content: [{ type: "text", text: `LinkedIn post comments API error: ${formatError(error)}` }], isError: true }; } } );
• src/types.ts:87-92 (schema)

  TypeScript interface defining expected input arguments for the tool, matching the inline Zod schema.
  export interface GetLinkedinPostCommentsArgs { urn: string; sort?: "relevance" | "recent"; count?: number; timeout?: number; }
• src/types.ts:574-584 (schema)

  Type guard validation function for tool input arguments, checks urn contains 'activity:', valid sort options, numeric count/timeout.
  export function isValidGetLinkedinPostCommentsArgs( args: unknown ): args is GetLinkedinPostCommentsArgs { if (typeof args !== "object" || args === null) return false; const obj = args as Record<string, unknown>; if (typeof obj.urn !== "string" || !obj.urn.includes("activity:")) return false; if (obj.sort !== undefined && obj.sort !== "relevance" && obj.sort !== "recent") return false; if (obj.count !== undefined && typeof obj.count !== "number") return false; if (obj.timeout !== undefined && typeof obj.timeout !== "number") return false; return true; }
• src/index.ts:100-145 (helper)

  Shared helper function that performs all API calls to AnySite.io. Handles HTTPS POST requests with authentication (access-token, optional account-id), JSON parsing, and error handling.
  const makeRequest = (endpoint: string, data: any, method: string = "POST"): Promise<any> => { return new Promise((resolve, reject) => { const url = new URL(endpoint, API_CONFIG.BASE_URL); const postData = JSON.stringify(data); const options = { hostname: url.hostname, port: url.port || 443, path: url.pathname, method: method, headers: { "Content-Type": "application/json", "Content-Length": Buffer.byteLength(postData), "access-token": API_KEY, ...(ACCOUNT_ID && { "x-account-id": ACCOUNT_ID }) } }; const req = https.request(options, (res) => { let responseData = ""; res.on("data", (chunk) => { responseData += chunk; }); res.on("end", () => { try { const parsed = JSON.parse(responseData); if (res.statusCode && res.statusCode >= 200 && res.statusCode < 300) { resolve(parsed); } else { reject(new Error(`API error ${res.statusCode}: ${JSON.stringify(parsed)}`)); } } catch (e) { reject(new Error(`Failed to parse response: ${responseData}`)); } }); }); req.on("error", (error) => { reject(error); }); req.write(postData); req.end(); }); };
• src/index.ts:19-72 (helper)

  API configuration object defining base URL and all endpoints. The tool uses API_CONFIG.ENDPOINTS.LINKEDIN_POST_COMMENTS.
  const API_CONFIG = { BASE_URL: "https://api.anysite.io", ENDPOINTS: { SEARCH_USERS: "/api/linkedin/search/users", USER_PROFILE: "/api/linkedin/user", LINKEDIN_EMAIL: "/api/linkedin/email/user", LINKEDIN_USER_POSTS: "/api/linkedin/user/posts", LINKEDIN_USER_REACTIONS: "/api/linkedin/user/reactions", LINKEDIN_USER_COMMENTS: "/api/linkedin/user/comments", LINKEDIN_SEARCH_POSTS: "/api/linkedin/search/posts", REDDIT_SEARCH_POSTS: "/api/reddit/search/posts", REDDIT_POSTS: "/api/reddit/posts", REDDIT_POST_COMMENTS: "/api/reddit/posts/comments", CHAT_MESSAGES: "/api/linkedin/management/chat/messages", CHAT_MESSAGE: "/api/linkedin/management/chat/message", USER_CONNECTION: "/api/linkedin/management/user/connection", POST_COMMENT: "/api/linkedin/management/post/comment", USER_CONNECTIONS: "/api/linkedin/management/user/connections", LINKEDIN_POST_REPOSTS: "/api/linkedin/post/reposts", LINKEDIN_POST_COMMENTS: "/api/linkedin/post/comments", LINKEDIN_POST_REACTIONS: "/api/linkedin/post/reactions", LINKEDIN_GOOGLE_COMPANY: "/api/linkedin/google/company", LINKEDIN_COMPANY: "/api/linkedin/company", LINKEDIN_COMPANY_EMPLOYEES: "/api/linkedin/company/employees", LINKEDIN_COMPANY_POSTS: "/api/linkedin/company/posts", LINKEDIN_POST: "/api/linkedin/management/post", LINKEDIN_SN_SEARCH_USERS: "/api/linkedin/sn_search/users", CONVERSATIONS: "/api/linkedin/management/conversations", GOOGLE_SEARCH: "/api/google/search", INSTAGRAM_USER: "/api/instagram/user", INSTAGRAM_USER_POSTS: "/api/instagram/user/posts", INSTAGRAM_POST_COMMENTS: "/api/instagram/post/comments", // New LinkedIn endpoints LINKEDIN_USER_ENDORSERS: "/api/linkedin/user/endorsers", LINKEDIN_USER_CERTIFICATES: "/api/linkedin/user/certificates", LINKEDIN_USER_EMAIL_DB: "/api/linkedin/user/email", LINKEDIN_MANAGEMENT_ME: "/api/linkedin/management/me", // New Instagram endpoints INSTAGRAM_POST: "/api/instagram/post", INSTAGRAM_POST_LIKES: "/api/instagram/post/likes", INSTAGRAM_USER_FRIENDSHIPS: "/api/instagram/user/friendships", INSTAGRAM_SEARCH_POSTS: "/api/instagram/search/posts", INSTAGRAM_USER_REELS: "/api/instagram/user/reels", // Twitter/X endpoints TWITTER_USER: "/api/twitter/user", TWITTER_SEARCH_USERS: "/api/twitter/search/users", TWITTER_USER_POSTS: "/api/twitter/user/posts", TWITTER_SEARCH_POSTS: "/api/twitter/search/posts", TWITTER_POST: "/api/twitter/post", // Web Parser endpoints WEBPARSER_PARSE: "/api/webparser/parse", WEBPARSER_SITEMAP: "/api/webparser/sitemap" } };
