ChatGPT

Add Cakewalk's MCP Gateway as a custom connector at chatgpt.com. The connector propagates to ChatGPT Desktop via your ChatGPT account.

ChatGPT reads remote MCP servers from custom connectors configured in your ChatGPT account. Add the Cakewalk gateway once at chatgpt.com. The connector appears in ChatGPT (web chat) and ChatGPT Desktop automatically.

Requirements

• ChatGPT Business, Enterprise or Edu workspace. Plus and Pro accounts can add custom MCP connectors but are restricted to read or fetch tool calls only; write-capable MCP (what Cakewalk's gateway proxies) requires a workspace plan.
• Workspace owner or admin role to enable Developer Mode and create the connector.

Install Method

Custom form at chatgpt.com. Configuration is brokered through your ChatGPT account. ChatGPT Desktop and chatgpt.com share the same connectors.

Step 1: Enable Developer Mode

Developer Mode is required to add custom MCP connectors.

1. In chatgpt.com, click your account icon (bottom left).
2. Click Settings.
3. Click Connectors (relabeled Apps in newer ChatGPT UI versions).
4. Click Advanced settings.
5. Toggle Developer mode on.

Step 2: Create the Connector

1. Return to the Connectors (or Apps) page.
2. Click Create.
3. Fill the form:

   • Name: a descriptive name like All company apps (see the tip below)
   • MCP URL: https://mcp-gateway.getcakewalk.io/mcp/meta
   • Authentication: leave as OAuth
   • I trust this application: check
4. Submit the form.

Name the connector for what it does, not "Cakewalk." ChatGPT decides whether to use a connector partly from its name. A descriptive name like "All company apps" helps it find the gateway across every model.

Use the /mcp/meta URL, not /mcp. ChatGPT cuts off long tool lists, so a connector that exposes every tool your company has approved can fail to load. The /mcp/meta endpoint presents three tools instead (list, describe, run) and ChatGPT reaches everything else through them. One connector then covers every app you have connected, however many that is.

Step 3: Authenticate

ChatGPT opens the OAuth flow in your browser. Sign in with your Cakewalk account and approve the Connection.

Verifying It Works

In a ChatGPT conversation, ask ChatGPT to list its available tools. The tools surfaced through the Cakewalk gateway appear in the response. In Cakewalk, the ChatGPT card on My Agents flips to Connected after the first agent call.

Where the Connector Appears

After you add the connector at chatgpt.com, it appears in:

• ChatGPT (chat at chatgpt.com), per conversation, once enabled.
• ChatGPT Desktop (Mac, Windows), per conversation, once enabled.

There is no separate setup step in ChatGPT Desktop. If the Cakewalk connector does not appear there after you add it at chatgpt.com, restart the app.

Troubleshooting

• Developer Mode toggle is missing: the toggle is restricted by plan tier. See Requirements above.
• OAuth flow returns to an error page: copy the full callback URL from your browser's address bar and paste it back into the prompt at chatgpt.com.
