marketo_delete_channel

Instructions

Implementation Reference

• src/index.ts:244-246 (handler)

  The handler function that executes the marketo_delete_channel tool logic. Makes a POST request to /asset/v1/channel/{channelId}/delete.json to delete a channel by its numeric ID.

  tool(async ({ channelId }) =>
    makeApiRequest(`/asset/v1/channel/${channelId}/delete.json`, 'POST')
  )

• src/index.ts:243-243 (schema)

  The input schema for marketo_delete_channel, defined using Zod. Accepts a single required parameter: channelId (number).

  { channelId: z.number() },

• src/index.ts:240-247 (registration)

  Registration of the tool on the McpServer via server.tool() with name 'marketo_delete_channel', description, Zod schema, and handler wrapped in the tool() error-handling helper.

  server.tool(
    'marketo_delete_channel',
    'Delete a channel by ID. Fails if any programs are currently using this channel.',
    { channelId: z.number() },
    tool(async ({ channelId }) =>
      makeApiRequest(`/asset/v1/channel/${channelId}/delete.json`, 'POST')
    )
  );

• src/index.ts:23-53 (helper)

  The makeApiRequest helper function used by the handler to make authenticated HTTP requests to Marketo REST API endpoints. Handles token injection, content-type formatting, and error logging.

  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:55-73 (helper)

  The tool() wrapper helper that provides standardized error handling and response formatting for all tool handlers, including marketo_delete_channel.

  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,
        };
      }
    };
