Brief
Brex open-sourced CrabTrap on April 21, 2026 — a proxy developed by Pedro Franceschi that intercepts outbound requests from LLM-driven agents and uses LLMs to judge and block risky network activity before it reaches external APIs. Brex deployed agents on OpenClaw internally and positions CrabTrap as a promising step toward secure, production-grade agent harnesses; the repo is public and the company is hiring.
Why it matters
Brex open-sourced CrabTrap on 2026-04-21 — a proxy that intercepts every outbound request from AI agents and uses LLMs to block risky activity before requests hit external APIs (announced by Pedro Franceschi @pedroh96).
Key details
- Brex deployed agents internally at @brexHQ to run their operations on OpenClaw (called the "fastest-growing open source project" by Franceschi) and used CrabTrap to avoid giving agents real credentials; the team describes results as "promising."
