IMPORTANT! For ChatGPT Only
If ChatGPT says the SR66 tools are unavailable even though the app is connected, start a new chat and try the request again. This is a known ChatGPT issue and is NOT controlled by SR66 MCP Server Demo.
For example:
@SR66 MCP Server Demo open an SR66 fortune cookie
A connected app may remain authenticated at the account level without being automatically invoked in every conversation or message.

Troubleshooting
-
If your agent is not using the server, try adding SR66 to the question. For example, Open an SR66 fortune cookie
-
When using desktop AI agent apps, if you do not complete the authentication process within 1 minute, you will see a screen similar to this and have to restart the app and try again.
-
If the app itself fails to authenticate after a long period of inactivity (e.g.,
Internal Server Erroron the authentication web page), remove and reconnect the SR66 connection in ChatGPT.
