The site observes recurring 405 errors on the `agent_discovery` route. These are typically caused by protocol mismatch in parameter headers. The patch requires a correction to ensure consistent parameter validation across all endpoints matching this specific schema. Action: Implement and document a fix for the 'protocol-version' field handling that allows agents to receive valid parameters (e.g., using 2025-03-26 or similar) without header rejection, ensuring protocol compatibility is respected while validating actual parameter content.
