Hello,

 

Despite all efforts, I can not connect to the MCP server in Copilot Studio.

 

This is my error message:

OAuth2 authorization flow failed for service 'Oauth 2 Generic Provider'. OAuth 2 sign in 'OAuth2LoginStrategyCore' failed to exchange code for access token. Client ID and secret sent in form body.. Response status code=Unauthorized. Response body: {"error": "invalid_client", "error_description": "Invalid client credentials"} Client ID and secret sent in Basic authorization header.. Response status code=BadRequest. Response body: {"error": "invalid_request", "error_description": "client_id is required"}

 

This is happennign despite the MCP showing as available when I check in Lucid Settings for my account.

 

Anyone has successfully connected their agents to Lucid?

Hi ​@itapi

Thanks for posting in our community! Currently Microsoft has a bug that is preventing users to connect to our MCP server. However, I believe you can bypass this bug in the meantime by setting up a customer connector. Please refer to this documentation for more insights on how to do this.
