A local proxy that stops secrets from reaching LLM APIs. It inspects every request to an AI provider before it leaves your machine and blocks, redacts or placeholder-swaps API keys, passwords and other secrets. Works with Claude Code, Cursor, Codex, Aider and anything built on the Python or Node SDKs.
