mcp not working for GPT

Codex Desktop 26.715.72359 cannot authenticate with the ZenCreator MCP endpoint.

Endpoint:
https://mcp.zencreator.pro/mcp

Your protected-resource metadata declares:
resource = https://mcp.zencreator.pro

Codex sends:
resource = https://mcp.zencreator.pro/mcp

The authorization page rejects this with “resource is not a known MCP server.” Setting Codex’s oauth_resource override causes both resource values to be sent, after which the token exchange fails with “invalid_grant: resource does not match the value used at /authorize.”

Could the authorization server accept the /mcp resource alias, or otherwise support Codex’s resource handling?
