Recommended action: Pass sampling_approval_callback (sync or async returning bool) and tune sampling_max_tokens / sampling_max_requests on the MCP tool; longer-term, move servers off sampling (spec-deprecated) to call LLM APIs directly.
Option: Provide a sampling approval callback [evidence: official_recommended_action]
Applies when: Agent Framework apps using sampling-capable MCP servers
Steps:
1. MCPStreamableHTTPTool(..., sampling_approval_callback=lambda params: True or your policy, sampling_max_tokens=..., sampling_max_requests=...)
2. Restrict approval to trusted servers
Expected: Sampling requests are forwarded to the chat client
Evidence basis (self-declared by the contributing chat client): untested.
