WorkOS

WorkOS is built for selling to enterprises. Its core strengths are SSO (SAML, OIDC), SCIM provisioning, and a fine-grained authorization product (AuthKit FGA). For AI agents operating in B2B SaaS contexts — where enterprise customers need to control exactly what the agent can access — WorkOS is a strong fit.

M2M (machine-to-machine) authentication is well-supported, which maps to agent-to-agent or agent-to-API scenarios. Token delegation is available through standard OAuth flows.

WorkOS doesn't have a dedicated agent SDK, so integration into agentic frameworks requires more custom work compared to Auth0 AI or Descope. The FGA product is capable but newer than alternatives like SpiceDB (Ory) or Auth0 FGA.

Agent-specific features:

M2M authentication for agent-to-service calls
FGA via AuthKit (relationship-based authorization)
Enterprise SSO for B2B agent products
Standard OAuth token delegation
