Permit.io has introduced AI Access Control, a tool designed to enhance the security of AI-powered applications through fine-grained identity management. Central to this launch is the Four-Perimeter Framework, which secures AI interactions from prompt input to final response by incorporating integrations like LangChain, LangFlow, PydanticAI, and the Model Context Protocol (MCP). These integrations enable authentication, authorization, and data filtering, ensuring AI operations remain secure and compliant. The framework applies strict controls on inputs, data access, external operations, and responses, reducing risks such as unauthorized access, data leaks, and compliance violations. By implementing identity-based permissions, developers can manage AI agent interactions with external systems, ensuring accountability and traceability. This initiative aims to make AI security seamless for developers while promoting responsible AI behavior.
