Your AI assistant, wired into the wire.

A local MCP server exposes your captured traffic to Claude Code, Cursor, and VS Code — they can search, inspect, and replay requests. Runs over a Unix socket; nothing leaves your Mac.

1. Ask: "why is /checkout failing?"
2. search_requests("/checkout") → 402
3. get_request(482) → card_declined
4. replay_request(482) with a fix

Built for trust, priced for indies.
