Im trying to connect the MCP tools in another AI that is not claude or chat gpt, I'm facing an issue with the OAUTH authentication, when i TRY TO AUTHENTICATE, Received following query parameters: {"state":"eyJ0b2tlbiI6InIzWVRTZjZuLTBOOW9vT2pTZ09yU25felBHWnZDcTJWWkVaOCIsImNpZCI6IkROZUhKamUwYzFTTUIycHUiLCJjcmVhdGVkQXQiOjE3NTk5MDg4MTIyODMsInVzZXJJZCI6IjExNWFhY2FjLTA0OGEtNGJjOC1iN2IwLWZlMDc3OWJhYjQxNyIsImhvc3QiOiJhdHlwaWNhbHRlY2guYXBwLm44bi5jbG91ZC9yZXN0In0=","role":"1309","entity":"11934","company":"XXXXX","error":"invalid_request"}

What is the

redirect_uri

being passed in the Step One of the Auth process? Note: The value of the redirect URI parameter must match the redirect URI in the corresponding integration record.

https://oauth.n8n.cloud/oauth2/callback and they are the same. It is working well for rest_webservices. The difference on this authentication is the scope that I'm using MCP\

invalid_request

error corresponds to

One or more required parameters are missing.

as per the official docs Authorization Errors in Step One
