About
Permit.io adds fine-grained authorization to apps, APIs and AI agents. Policies can be modeled in a UI or as code and enforced with an SDK call such as check, and the policy decision point can run next to your services. It also offers an MCP Gateway that checks every tool call against policy before it reaches an MCP server.
Use cases: identity-access
