Report #60712

[frontier] Agent tool calls mutate production state dangerously without validation

Execute tool calls in isolated shadow MCP servers \(Docker-in-Docker or E2B sandbox\) before committing to production; validate side effects in sandbox

Journey Context:
Dry-run flags are inconsistently implemented across tools; shadow execution spins up ephemeral MCP server instances with mock credentials \(isolated Docker containers or sandboxed environments like E2B\) to execute the agent's proposed tool calls; captures side effects \(file writes, DB changes\) without risk; diff the shadow output against expected state; only commit to production MCP servers after validation; requires containerized MCP servers and state reset between runs
