Prefactor FAQ
What exactly is an "AI Agent Control Plane"?
Think of it like the control tower at a major airport. Individual AI agent frameworks (LangChain, CrewAI, etc.) are the planes—they do the actual work. The control plane is the essential layer of infrastructure that manages the traffic: it gives each "plane" (agent) a unique identity, dictates its permissions (flight path), monitors its every move in real-time, and maintains a perfect log of all activity. It's the system that brings order, safety, and governance to autonomous operations.
How does Prefactor work with existing AI agent frameworks?
Prefactor is designed to be framework-agnostic. It provides SDKs and integrations that work seamlessly with popular frameworks like LangChain, CrewAI, and AutoGen, as well as custom-built agents. You can deploy it alongside your existing agents, often in just hours. It doesn't replace your framework; it adds the critical production-grade governance layer that these frameworks typically lack.
Is Prefactor only for large, regulated enterprises?
While its features are absolutely essential for regulated industries (finance, healthcare, etc.), any team moving multiple AI agents from demo to real-world production will benefit. If you care about knowing what your agents are doing, controlling their access, having audit trails, and managing costs, Prefactor provides the enterprise-ready infrastructure so you don't have to build it from scratch.
What is MCP and how does Prefactor relate to it?
Model Context Protocol (MCP) is becoming a standard way for AI agents to connect to tools and data sources. Prefactor's whitepaper "MCP in Production" addresses the critical gap: while MCP enables connectivity, teams are "flying blind" in production without governance. Prefactor acts as the control plane for MCP-enabled agents, providing the essential visibility, audit, and security controls needed to use MCP safely at scale.
