marketo_get_smart_lists

Instructions

Implementation Reference

• src/tools/smartLists.ts:14-21 (handler)

  The async handler function for marketo_get_smart_lists. It takes optional maxReturn and offset args, builds query params, calls makeRequest to GET /rest/asset/v1/smartLists.json, and returns the response via the ok helper.

  async (args) => {
    try {
      const params: Record<string, unknown> = {};
      if (args.maxReturn) params.maxReturn = args.maxReturn;
      if (args.offset) params.offset = args.offset;
      return ok(await makeRequest("/rest/asset/v1/smartLists.json", "GET", params));
    } catch (e) { return err(e); }
  }

• src/tools/smartLists.ts:10-13 (schema)

  Zod schema for the tool's input: optional maxReturn (number, 1-200, default 20) and offset (number) for pagination.

  {
    maxReturn: z.number().optional().describe("Max smart lists to return (1-200, default 20)"),
    offset: z.number().optional().describe("Pagination offset"),
  },

• src/tools/smartLists.ts:7-22 (registration)

  Registration of the tool via server.tool() with the name 'marketo_get_smart_lists' and a description. Called from registerSmartListTools which is invoked in src/index.ts line 25.

  server.tool(
    "marketo_get_smart_lists",
    "List smart lists in Marketo. Returns smart list metadata including name, folder, created/updated dates, and filter rules summary.",
    {
      maxReturn: z.number().optional().describe("Max smart lists to return (1-200, default 20)"),
      offset: z.number().optional().describe("Pagination offset"),
    },
    async (args) => {
      try {
        const params: Record<string, unknown> = {};
        if (args.maxReturn) params.maxReturn = args.maxReturn;
        if (args.offset) params.offset = args.offset;
        return ok(await makeRequest("/rest/asset/v1/smartLists.json", "GET", params));
      } catch (e) { return err(e); }
    }
  );

• src/index.ts:20-29 (registration)

  Top-level registration: registerSmartListTools(server) wires the smart list tools (including marketo_get_smart_lists) into the MCP server.

  // Register all tool groups
  registerFormTools(server);
  registerLeadTools(server);
  registerProgramTools(server);
  registerEmailTools(server);
  registerSmartListTools(server);
  registerListTools(server);
  registerChannelTools(server);
  registerLandingPageTools(server);
  registerBulkExportTools(server);

• src/client.ts:21-49 (helper)

  The makeRequest helper that executes authenticated HTTP requests to the Marketo API. Used by the smart list handler to call the Marketo REST endpoint.

  export async function makeRequest<T = unknown>(
    endpoint: string,
    method: Method = "GET",
    data?: unknown,
    contentType?: string,
  ): Promise<T> {
    const token = await getAccessToken();
    const config: AxiosRequestConfig = {
      url: `${MARKETO_BASE_URL}${endpoint}`,
      method,
      headers: {
        Authorization: `Bearer ${token}`,
        ...(contentType ? { "Content-Type": contentType } : {}),
      },
      ...(data && method !== "GET" ? { data } : {}),
      ...(data && method === "GET" ? { params: data } : {}),
    };
  
    const res = await axios(config);
    const body = res.data;
  
    // Marketo REST API returns errors inside the response body
    if (body?.errors?.length) {
      const e = body.errors[0];
      throw new MarketoError(`${e.code}: ${e.message}`, res.status);
    }
  
    return body as T;
  }
