As AI agents become more autonomous, their roles have expanded from simple assistants to proactive entities capable of executing tasks, accessing APIs, and controlling infrastructure, which introduces risks of unauthorized actions and data breaches. Permit.io’s Access Request Model Context Protocol (MCP) offers a solution by integrating human-in-the-loop (HITL) workflows, ensuring that AI agents request permission for sensitive actions, with humans having the final authority to approve or deny these requests. This approach enhances safety, accountability, and control, by requiring explicit human sign-off for high-stakes operations. The system is built on Permit.io’s policy engine and integrates with popular agent frameworks such as LangChain and LangGraph, allowing developers to incorporate approval workflows into LLM-powered applications. By blending LLM intelligence with human oversight, the Access Request MCP framework provides a structured method for managing AI permissions, mitigating risks associated with over-permissive agents, hallucinated tool calls, and lack of auditability, thereby fostering more trustworthy AI systems.
