business_profile

Instructions

Implementation Reference

• src/server.ts:34-36 (registration)

  Registers business_profile tool via registerBusinessTools call in the MCP server initialization.

  registerAccountTools(server, getAuth);
  registerSerpTools(server, getAuth);
  registerBusinessTools(server, getAuth);

• src/tools/business.ts:11-29 (handler)

  The registerBusinessTools function registers the 'business_profile' tool with its handler, which calls the API endpoint /v1/business/profile with business_name, location, and optional place_id parameters.

  export function registerBusinessTools(server: McpServer, getAuth: () => string) {
    server.tool(
      "business_profile",
      "Get a complete Google Business Profile including name, rating, reviews, address, phone, website, hours, categories, attributes, photos count, description, and verification status. Costs 2 credits.",
      {
        business_name: z.string().describe("Business name"),
        location: z.string().describe("City and state"),
        place_id: z.string().optional().describe("Google Place ID for exact match"),
      },
      READ_ONLY,
      withErrorHandling(async ({ business_name, location, place_id }) => {
        const result = await callApi(
          "/v1/business/profile",
          { business_name, location, ...(place_id && { place_id }) },
          getAuth()
        );
        return { content: [{ type: "text" as const, text: formatResult(result.data, result) }] };
      })
    );

• src/tools/business.ts:15-19 (schema)

  Zod schema defining input parameters: business_name (string, required), location (string, required), place_id (string, optional).

  {
    business_name: z.string().describe("Business name"),
    location: z.string().describe("City and state"),
    place_id: z.string().optional().describe("Google Place ID for exact match"),
  },

• src/api-client.ts:25-92 (helper)

  The callApi helper function that makes authenticated POST requests to the API. Used by the business_profile handler.

  export async function callApi(
    path: string,
    body: Record<string, unknown>,
    authHeader: string,
    timeoutMs = 60_000
  ): Promise<{ data: unknown; credits_used: number; credits_remaining: number; cached: boolean }> {
    const url = `${env.API_BASE_URL}${path}`;
  
    console.log(`[api] POST ${url} (timeout: ${timeoutMs / 1000}s, auth: ${authHeader ? `${authHeader.slice(0, 15)}...` : "MISSING"})`);
  
    const response = await fetch(url, {
      method: "POST",
      headers: {
        "Content-Type": "application/json",
        Authorization: authHeader,
      },
      body: JSON.stringify(body),
      signal: AbortSignal.timeout(timeoutMs),
    });
  
    if (!response.ok) {
      const text = await response.text();
      console.error(`[api] ${response.status} ${response.statusText} from ${path}: ${text.slice(0, 200)}`);
      // Try to parse as structured error
      try {
        const result = JSON.parse(text) as ApiErrorResponse;
        if (result.status === "error") {
          const err = result.error;
          const reqId = result.request_id ? ` [request_id: ${result.request_id}]` : "";
          throw new Error(
            err.required_credits
              ? `${err.message} (requires ${err.required_credits} credits, balance: ${err.current_balance})${reqId}`
              : `${err.message}${reqId}`
          );
        }
      } catch (parseErr) {
        if (parseErr instanceof Error && parseErr.message !== "error") {
          // Re-throw if it's our structured error from above
          if (!text.includes('"status":"error"')) {
            throw new Error(`API returned ${response.status}: ${text.slice(0, 200)}`);
          }
          throw parseErr;
        }
      }
      throw new Error(`API returned ${response.status}: ${text.slice(0, 200)}`);
    }
  
    const result = (await response.json()) as ApiResponse;
  
    if (result.status === "error") {
      const err = (result as ApiErrorResponse).error;
      const reqId = (result as ApiErrorResponse).request_id ? ` [request_id: ${(result as ApiErrorResponse).request_id}]` : "";
      throw new Error(
        err.required_credits
          ? `${err.message} (requires ${err.required_credits} credits, balance: ${err.current_balance})${reqId}`
          : `${err.message}${reqId}`
      );
    }
  
    console.log(`[api] ${path} OK (${result.credits_used} credits used, ${result.credits_remaining} remaining)`);
  
    return {
      data: result.data,
      credits_used: result.credits_used,
      credits_remaining: result.credits_remaining,
      cached: result.cached,
    };
  }

• src/api-client.ts:143-158 (helper)

  The withErrorHandling wrapper that catches errors from the tool handler and returns them as MCP error content.

  export function withErrorHandling<T>(
    fn: (args: T) => Promise<ToolResult>
  ): (args: T) => Promise<ToolResult> {
    return async (args) => {
      try {
        return await fn(args);
      } catch (err) {
        const message = err instanceof Error ? err.message : String(err);
        console.error(`[mcp] Tool error: ${message}`);
        return {
          content: [{ type: "text" as const, text: `Error: ${message}` }],
          isError: true,
        };
      }
    };
  }
