Validate that Claude is capable of authenticating with ToolHive

[yrobla]

Run an mcp server with toolhive, with auth enabled. Check if Claude is supporting it. Typically can be tested with:

claude mcp add...
claude
then select the mcp from list and click on authenticate```

[yrobla]

when authenticating i get:

 Error: HTTP 403: Invalid OAuth error response: [                                                                      │
