agent-chaperone
Stdio MCP proxy that screens agent tool calls and returned content against configurable policy thresholds, logs probability-based decisions, and starts in non-blocking shadow mode. Screening can send tool arguments or results to a configured model backend after secret-pattern redaction; it is not a sandbox. Public repository created September 18, 2026.
