Open-source permissions for AI agents

About

I build infrastructure for AI agent safety. After years of working on agent systems professionally, I kept seeing the same gap: AI agents get full access to your tools and data, or you don't use them at all. Multicorn Shield is an open-source permission layer that sits between agents and your services - every action is checked, logged, and only executed with your approval. I'm building this because agent governance is too important to leave to system prompts.

Multicorn Shield - Permissions, approvals & audit trails for AI agents

AI agents today get full access or no access. There's no permission layer. Multicorn Shield intercepts every tool call before it executes, checks it against your permissions, and blocks anything unauthorized. Real-time approval requests, time-limited access, spending controls, and tamper-proof audit logs. Open source, works as an MCP proxy, 2-minute setup. Also includes free AI safety education at multicorn.ai/learn.
