Was a beautiful and detailed description. Everything worked perfectly until I tried to start the deployed version in the playground. Receive a “Connection error: SSE error: Failed to fetch”. Checked the domain, client_id .. about 5 times. Can’t find out, whether the error is on my side. Nevertheless, all curl tests are successfull.
How was it possible for Claude to validate the credentials?
Great question @sota
After you update the Claude Desktop configuration to point to the URL of your MCP server, you’ll restart Claude Desktop and get redirected to Auth0 to complete the authentication flow. Auth0 validates the credentials and returns the authentication results to the Auth0 remote MCP Server.
