ChatGPT
Add MuseCanto as a remote MCP connector in ChatGPT on the web, then read and write workspace content from chat.
On ChatGPT for web (chatgpt.com), MuseCanto can be added as a custom MCP connector. After OAuth, ChatGPT can search knowledge books, inspect the topic calendar, and create documents or X drafts within the granted scopes. ChatGPT only reaches public HTTPS MCP servers; local stdio processes are not supported.
Plan and menus
Custom MCP connectors require a paid plan (Plus / Pro / Business / Enterprise / Edu) and currently work best on the web app. The settings label may read Apps, Connectors, or Apps & Connectors.
1. Turn on Developer Mode
Sign in at ChatGPT and open Settings from your profile menu.
Go to Apps / Connectors → Advanced settings and toggle Developer Mode. On Business or Enterprise workspaces, an admin may need to allow this first.
2. Create the MuseCanto connector
On the connector list, click Create (or Add custom connector) and fill in:
| Field | Suggested value |
|---|---|
| Name | MuseCanto |
| MCP server URL | https://mcp.musecanto.com/mcp |
| Authentication | OAuth |
Server URL
On a custom domain, paste the URL from MCP
Settings. Do not put API keys or browser cookies in
the connector. http://localhost is not reachable from ChatGPT.
Confirm that you trust the app, then create it. ChatGPT opens the MuseCanto OAuth page; approve the workspace scopes and return to ChatGPT.
3. Enable it in a chat and verify
Start a new chat, open the + menu, choose Developer Mode, and tick
MuseCanto. New chats do not inherit the selection automatically.
Send: text Call MuseCanto whoami and list_organizations to confirm my account and workspaces. A profile plus workspace list means the
connector is live.
