marketo_get_emails

Instructions

Implementation Reference

• src/index.ts:508-515 (handler)

  The handler function for the 'marketo_get_emails' tool. It constructs query params (maxReturn, offset, status) and calls the Marketo Asset API GET /asset/v1/emails.json endpoint.

  tool(async ({ maxReturn = 200, offset = 0, status }) => {
    const params = new URLSearchParams({
      maxReturn: maxReturn.toString(),
      offset: offset.toString(),
    });
    if (status) params.append('status', status);
    return makeApiRequest(`/asset/v1/emails.json?${params.toString()}`, 'GET');
  })

• src/index.ts:503-507 (schema)

  Input schema for the 'marketo_get_emails' tool: optional maxReturn (number), offset (number), and status (enum: approved/draft), validated with Zod.

  {
    maxReturn: z.number().optional(),
    offset: z.number().optional(),
    status: z.enum(['approved', 'draft']).optional(),
  },

• src/index.ts:500-516 (registration)

  Registration of the 'marketo_get_emails' tool on the MCP server via server.tool(), including its name, description, input schema, and handler.

  server.tool(
    'marketo_get_emails',
    'List email assets in Marketo. Filter by approval status (approved/draft) and paginate with maxReturn/offset. Returns email metadata including subject line, from address, and template ID.',
    {
      maxReturn: z.number().optional(),
      offset: z.number().optional(),
      status: z.enum(['approved', 'draft']).optional(),
    },
    tool(async ({ maxReturn = 200, offset = 0, status }) => {
      const params = new URLSearchParams({
        maxReturn: maxReturn.toString(),
        offset: offset.toString(),
      });
      if (status) params.append('status', status);
      return makeApiRequest(`/asset/v1/emails.json?${params.toString()}`, 'GET');
    })
  );

• src/index.ts:23-53 (helper)

  The makeApiRequest helper function used by the handler to execute HTTP requests to Marketo's REST API with proper auth headers.

  async function makeApiRequest(
    endpoint: string,
    method: string,
    data?: any,
    contentType: string = 'application/json'
  ) {
    const token = await tokenManager.getToken();
    const headers: Record<string, string> = {
      Authorization: `Bearer ${token}`,
    };
  
    if (contentType) {
      headers['Content-Type'] = contentType;
    }
  
    try {
      const response = await axios({
        url: `${MARKETO_BASE_URL}${endpoint}`,
        method,
        data:
          contentType === 'application/x-www-form-urlencoded'
            ? new URLSearchParams(data).toString()
            : data,
        headers,
      });
      return response.data;
    } catch (error: any) {
      console.error('API request failed:', error.response?.data || error.message);
      throw error;
    }
  }

• src/index.ts:55-74 (helper)

  The tool() wrapper function that wraps each handler to catch errors and return a standardized MCP content response.

  function tool<T>(handler: (args: T) => Promise<unknown>) {
    return async (args: T) => {
      try {
        const response = await handler(args);
        return {
          content: [{ type: 'text' as const, text: JSON.stringify(response, null, 2) }],
        };
      } catch (error: any) {
        return {
          content: [
            {
              type: 'text' as const,
              text: `Error: ${error.response?.data?.message || error.message}`,
            },
          ],
          isError: true,
        };
      }
    };
  }
