Stytch Review 2026

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.
