Prefactor is the agent identity platform for AI-native software. As more applications integrate with AI agents like ChatGPT, Claude, and open-source copilots, secure access is no longer just for humans โ€” agents need it too.

Prefactor helps SaaS platforms authenticate and authorize AI agents using the Model Context Protocol (MCP). We provide the infrastructure to control what agents can access, log every action, and prevent abuse โ€” without building complex identity plumbing in-house.

With Prefactor, you get:

Agent authentication via MCP and OAuth/OIDC bridges

Scoped, auditable access control

Version-controlled identity logic with our domain-specific language (DSL)

Drop-in SDKs and fast integration for developer teams

Weโ€™re building the missing identity layer for the agent-powered internet โ€” futureproof your app now.
