Reticle intercepts, visualizes, and profiles MCP JSON-RPC traffic in real time — designed for microsecond-level overhead.
MCP Reticle source profile. From the maintainer documentation: “Reticle intercepts, visualizes, and profiles MCP JSON-RPC traffic in real time — designed for microsecond-level overhead.”
Reticle is a proxy + UI for debugging MCP integrations: - inspect raw JSON-RPC messages (requests / notifications / responses) - correlate request ↔ response instantly - profile latency and token estimates - capture server stderr and crashes - record sessions and export logs
