WorkOS

Authentication

Enterprise auth platform for workforce identity and SSO/SAML integration.

What it solves

If your MCP server serves enterprise customers, those customers will ask for SSO and directory sync before their security team approves it. WorkOS gives you SAML SSO and SCIM provisioning as APIs, so your MCP server can pass an enterprise security review without you building SAML by hand.

How it works

You integrate WorkOS APIs into your server's auth flow. Enterprise admins configure their IdP (Okta, Entra, Google Workspace) on their side, and WorkOS normalizes the SAML/OIDC differences, handling login and user provisioning events for you.

Pros & cons

Pros

SSO and SCIM are the two features that most often block enterprise deals — this unblocks them.
Well-documented APIs, far less painful than implementing SAML yourself.
Usage-based pricing lets you start before you have enterprise customers.

Considerations

Solves the human-auth side — it does not govern what agents do after login.
Per-connection pricing grows as you add enterprise customers.
Another external dependency in your auth path.

When to choose it

Choose WorkOS when you build or operate an MCP server (or any B2B tool) that needs enterprise SSO and SCIM to pass customer security reviews.
