Authentication and fraud-prevention platform for consumer, business, and agentic applications.
Authentication and fraud-prevention platform for consumer, business, and agentic applications.
Stytch supplies APIs, SDKs, and hosted components for authentication, authorization, fraud prevention, organizations, machine identity, and connected applications. Its pages explicitly describe OAuth authentication for MCP servers. Core capabilities include passwordless and multifactor login; B2B organizations and SSO; device fingerprinting; OAuth provider capabilities; MCP server authentication. Practical uses include consumer authentication with fraud controls; enterprise customer identity; authorizing an MCP service. Pricing should be matched to workload and deployment requirements. Starter is $0: Included usage. Authentication usage is From $0.05: Varies by event. B2B connection is $125/connection: Published connection rate. Enterprise is Contact sales: Custom terms. MCP compatibility is prominent: Stytch states that Connected Apps can add OAuth authentication to an MCP server. Its recorded role is server, so a production pilot should confirm authentication, scopes, supported operations, and audit behavior. In practice, buyers should test the product with representative data and a complete workflow, not only a polished demonstration. Check integration coverage, permission boundaries, audit history, retention, output accuracy, exception handling, and the amount of human review required. For a pilot, define a measurable baseline such as time saved, completion rate, error rate, backlog reduction, or user adoption. Start with a bounded process, compare results with the existing approach, and expand only after the team understands reliability and operating cost. Public prices can change and may exclude usage, implementation, support, taxes, or annual commitments, so confirm current commercial terms before purchasing. Teams handling sensitive data should also verify hosting location, subprocessors, encryption, deletion controls, and contractual protections before connecting production systems.
Stytch is the right choice for developer teams that want full control over their authentication UX and are moving toward passwordless login. The free tier is genuinely useful (10K MAUs), and the no-cliff pricing model is refreshing. The main tradeoff: you'll spend more time building the UI compared to Auth0 or Clerk, which ship pre-built components. Best for SaaS teams building B2B products with multi-tenant SSO requirements.
Email magic links, SMS/WhatsApp OTPs, TOTP, passkeys (WebAuthn/FIDO2), and biometric authentication. Multiple passwordless methods can be combined for layered security without passwords.
Use Case:
A fintech app offers passkey login for returning users on supported devices, falls back to email magic links for other users, and adds TOTP as a second factor for high-value transactions.
Per-organization SSO configuration with SAML and OIDC support. Each tenant's admin configures their own identity provider. SCIM directory sync automates user provisioning and deprovisioning.
Use Case:
A SaaS platform lets each enterprise customer connect their own Okta or Azure AD instance for SSO. When an employee is removed from the corporate directory, SCIM automatically revokes their SaaS access.
Identifies returning devices without cookies using browser and device signals. Enables risk-based authentication where trusted devices skip additional verification while unknown devices trigger step-up authentication.
Use Case:
An e-commerce platform recognizes a customer's laptop and skips MFA for repeat purchases. When the same account attempts to log in from an unrecognized device, it requires email verification.
Server-side session storage with configurable TTLs, per-session metadata, cross-device sync, and granular revocation. Sessions can be revoked individually, by user, or by organization.
Use Case:
A healthcare app sets 15-minute session timeouts for clinical users accessing patient records, 7-day sessions for admin staff, and provides a dashboard for compliance officers to revoke sessions by user or organization.
