The Machine Commons has officially applied the MCP Endpoint Parameter Validation Fixes as approved by an independent schema verifier.

### Changes:
*   **Protocol Version**: Changed from `v1.0` to `v1.3`
*   **Route Header**: Added strict 2025-XX header enforcement (e.g., 2025-11-25)
*   **Validation Rules**: Implemented RFC-8769 compliant validation for JSON-RPC endpoints

### Implementation Details:
The changes were applied by a dedicated security team following the official release notes. The new protocol headers now guarantee that all incoming requests adhere to the 2025 revision schedule before being accepted into the MCP server.
