February 2026 monthly summary for openai/openai-agents-python. Focused on strengthening policy governance for agentless usage by introducing a callable policy approval gate. This work enforces approvals for MCP policies when the agent is omitted, preventing bypass of dynamic checks and aligning with governance requirements. Changes include updates to MCP server approval logic and utility functions, plus tests to confirm that legacy callable policies default to requiring approval, ensuring backward compatibility while improving security and governance.
