Prefactor is the Native MCP Identity Layer for Modern SaaS.
Users want GPT, Claude and other agents to do things in your product — not just read your docs.
Secure, authorize, and audit AI agents — not just users.
Secure, authorize, and audit AI agents via MCP
“It took us 2 weeks to build a basic MCP Auth solution… The MCP Spec isn't clear and very very complicated to integrate and get it right”
CTO, Venture backed AI company
Connect your customers' agents via Prefactor's MCP layer
The authentication infrastructure that grows with you—from MCP auth to agent identity. From MVP to enterprise, get ahead of the customer agent wave and let them in
Human Delegation // Agent Authorization
Human-delegated MCP authentication and access for AI agents, APIs, and services via SSO, MFA, Magic Links, Passkeys and Social Login
Designed to work alongside your human identity provision
Prefactor makes your MCP layer interoperable with existing OAuth/OIDC-based systems — so your agents can access APIs and apps just like a human would, but securely and programmatically.
Beyond RBAC: Scalable, Scoped Authorization for Autonomous Systems.
Support roles, attributes, and delegated access — in one unified model.
Built for SaaS apps with complex agent-based access patterns.
Agents Need First-Class Identity
Agents aren’t users. MFA, CAPTCHAs, and static roles break. Prefactor gives every agent a secure, autonomous identity — without duct tape via MCP
Control at Machine Scale
Hardcoded Access Slows You Down
Manually wiring permissions for every agent via MCP is brittle and slow. Prefactor lets you define access logic once — then scale instantly
Full Visibility for Every Action
Know who (or what) did what, when, and why. Prefactor gives you agent-level audit trails by default — not as an afterthought via MCP
Precision Control for Autonomous Agents
Give agents scoped, auditable access via MCP — governed by human intent, written in code, and deployed through your pipeline. All without building it yourself
“We didn’t need help with auth. We needed help with agents doing real things inside our app.”
CTO, Multiple SaaS companies
