Reticle MCP

Reticle MCP enables AI agents to verify their own code changes by inspecting the running web application's internal state, network traffic, and console logs. It records user flows for deterministic, low-cost replay and provides detailed failure evidence to help agents fix bugs without relying on screenshots or LLM reasoning.
