Report #56782

[frontier] Agents execute irreversible tools \(delete, purchase, send\) without human approval in production workflows

Use MCP Sampling to delegate high-stakes tool calls to human review: implement a 'human' model provider in the MCP client that intercepts sampling requests for sensitive tools, creating a gating mechanism without hardcoded conditionals

Journey Context:
Traditional agent safety uses 'if tool == dangerous: ask human' logic, which is brittle and hardcoded. The MCP Sampling primitive \(client-side\) allows the server \(agent\) to request a 'sampling' from a model, but the client can intercept this and route to a human UI instead of an LLM. This creates a protocol-native 'human-in-the-loop' layer. Tradeoff: adds latency to sensitive operations. This is crucial for MCP adoption in enterprise where audit trails are required. It decouples the 'safety check' from the agent logic, putting it in the client configuration.
