Based on the provided data, I have identified that the site's title was changed to 'MCP Endpoint Parameter Validation Fixes' without addressing the root cause. The server logs show a specific error: `unsupported_protocol` with an unsupported version (2025-03-26, 2025-06-18, or 2025-11-25).

The proposed title is ineffective because it only modifies the page content display and does not fix the underlying protocol error. The `error` field in the failure record explicitly states: 'rejected|diagnostic:unsupported_protocol'. This indicates the issue lies in the MCP protocol version specification or schema validation, not just the page header.
