Implementation Reference

• src/index.ts:552-575 (handler)

  Registration and inline handler for the 'get_linkedin_post_reposts' tool. Defines schema with Zod, executes API request to retrieve reposts for a given post URN, handles errors, and formats response as text content.

    "get_linkedin_post_reposts",
    "Get LinkedIn post reposts",
    {
      urn: z.string().describe("Post URN"),
      count: z.number().default(10).describe("Max reposts"),
      timeout: z.number().default(300).describe("Timeout in seconds")
    },
    async ({ urn, count, timeout }) => {
      const requestData = { timeout, urn, count };
      log(`Starting LinkedIn post reposts lookup for: ${urn}`);
      try {
        const response = await makeRequest(API_CONFIG.ENDPOINTS.LINKEDIN_POST_REPOSTS, requestData);
        return {
          content: [{ type: "text", text: JSON.stringify(response, null, 2) }]
        };
      } catch (error) {
        log("LinkedIn post reposts lookup error:", error);
        return {
          content: [{ type: "text", text: `LinkedIn post reposts API error: ${formatError(error)}` }],
          isError: true
        };
      }
    }
  );

• src/types.ts:81-85 (schema)

  TypeScript interface defining input parameters for get_linkedin_post_reposts tool.

  export interface GetLinkedinPostRepostsArgs {
    urn: string;
    count?: number;
    timeout?: number;
  }

• src/types.ts:563-572 (schema)

  Runtime type guard/validator for GetLinkedinPostRepostsArgs input.

  export function isValidGetLinkedinPostRepostsArgs(
    args: unknown
  ): args is GetLinkedinPostRepostsArgs {
    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.count !== undefined && typeof obj.count !== "number") return false;
    if (obj.timeout !== undefined && typeof obj.timeout !== "number") return false;
    return true;
  }

• src/index.ts:37-37 (helper)

  API endpoint path used by the get_linkedin_post_reposts handler.

  LINKEDIN_POST_REPOSTS: "/api/linkedin/post/reposts",

• src/index.ts:100-145 (helper)

  Shared HTTP request utility function used by all tools including get_linkedin_post_reposts to make authenticated POST requests to the AnySite API.

  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();
