• src/index.ts:1280-1329 (registration)

  Registration of the 'get-referrers' tool using server.tool(), including schema and handler.

  server.tool(
    "get-referrers",
    "View a site's referrers",
    {
      siteUrl: z.string().url().describe("WordPress site URL"),
      username: z.string().describe("WordPress username"),
      password: z.string().describe("WordPress application password"),
      siteId: z.number().describe("WordPress site ID"),
      period: z.enum(["day", "week", "month", "year"]).optional().describe("Time period for stats"),
      limit: z.number().min(1).max(100).optional().describe("Maximum number of referrers to return"),
    },
    async ({ siteUrl, username, password, siteId, period = "week", limit = 10 }) => {
      try {
        const referrersData = await makeWPRequest<{referrers: WPReferrer[]}>({
          siteUrl,
          endpoint: `sites/${siteId}/stats/referrers`,
          auth: { username, password },
          params: { period, limit }
        });
        
        const referrersText = Array.isArray(referrersData.referrers) && referrersData.referrers.length > 0
          ? referrersData.referrers.map((ref) => 
              `${ref.name || "Unknown"} (${ref.group || "Unknown Group"})
  URL: ${ref.url || "No URL"}
  Views: ${ref.views || 0}
  ${ref.is_spam ? "⚠️ Marked as spam" : ""}
  ---`
            ).join("\n")
          : "No referrers found";
        
        return {
          content: [
            {
              type: "text",
              text: `Referrers for site #${siteId} (${period}):\n\n${referrersText}`,
            },

              text: `Error retrieving referrers: ${error instanceof Error ? error.message : String(error)}`,
            },
          ],
        };
      }
    }
  );

• src/index.ts:1291-1328 (handler)

  Handler function that fetches referrer stats from WordPress Jetpack API endpoint `/sites/{siteId}/stats/referrers` and formats the response as text.

    async ({ siteUrl, username, password, siteId, period = "week", limit = 10 }) => {
      try {
        const referrersData = await makeWPRequest<{referrers: WPReferrer[]}>({
          siteUrl,
          endpoint: `sites/${siteId}/stats/referrers`,
          auth: { username, password },
          params: { period, limit }
        });
        
        const referrersText = Array.isArray(referrersData.referrers) && referrersData.referrers.length > 0
          ? referrersData.referrers.map((ref) => 
              `${ref.name || "Unknown"} (${ref.group || "Unknown Group"})
  URL: ${ref.url || "No URL"}
  Views: ${ref.views || 0}
  ${ref.is_spam ? "⚠️ Marked as spam" : ""}
  ---`
            ).join("\n")
          : "No referrers found";
        
        return {
          content: [
            {
              type: "text",
              text: `Referrers for site #${siteId} (${period}):\n\n${referrersText}`,
            },
          ],
        };
      } catch (error) {
        return {
          content: [
            {
              type: "text",
              text: `Error retrieving referrers: ${error instanceof Error ? error.message : String(error)}`,
            },
          ],
        };
      }
    }

• src/index.ts:1284-1290 (schema)

  Zod schema defining input parameters for the get-referrers tool.

    siteUrl: z.string().url().describe("WordPress site URL"),
    username: z.string().describe("WordPress username"),
    password: z.string().describe("WordPress application password"),
    siteId: z.number().describe("WordPress site ID"),
    period: z.enum(["day", "week", "month", "year"]).optional().describe("Time period for stats"),
    limit: z.number().min(1).max(100).optional().describe("Maximum number of referrers to return"),
  },

• src/index.ts:125-131 (schema)

  TypeScript interface defining the structure of a WPReferrer object used in the tool's response parsing.

  interface WPReferrer {
    group: string;
    name: string;
    url: string;
    views: number;
    is_spam?: boolean;
  }

• src/index.ts:158-194 (helper)

  Shared helper function used by the tool to make authenticated requests to WordPress REST API.

  async function makeWPRequest<T>({
    siteUrl, 
    endpoint,
    method = 'GET',
    auth,
    data = null,
    params = null
  }: {
    siteUrl: string;
    endpoint: string;
    method?: 'GET' | 'POST' | 'PUT' | 'DELETE';
    auth: { username: string; password: string };
    data?: any;
    params?: any;
  }): Promise<T> {
    const authString = Buffer.from(`${auth.username}:${auth.password}`).toString('base64');
    
    try {
      const response = await axios({
        method,
        url: `${siteUrl}/wp-json/wp/v2/${endpoint}`,
        headers: {
          'Authorization': `Basic ${authString}`,
          'Content-Type': 'application/json',
        },
        data: data,
        params: params
      });
      
      return response.data as T;
    } catch (error) {
      if (axios.isAxiosError(error) && error.response) {
        throw new Error(`WordPress API error: ${error.response.data?.message || error.message}`);
      }
      throw error;
    }
  }
