What Permit.io does
Provides real-time, fine-grained authorization and policy-backed delegation, approvals, trust, and audit for humans, services, and AI agents.
Why teams reach for it: Permit.io solves the problem of securing ephemeral AI agents by providing real-time, fine-grained authorization that replaces static permissions with policy-backed, just-in-time access.
Worth knowing
The product requires admin grants for user access to MCP servers and has specific trust level configurations that affect user permissions.

Who can connect, and what may they do?
Authorization & identity tools control who — or which AI agent — is allowed to connect, and what they're allowed to do once connected.
