Freemium

Open-source platform to test, debug and evaluate MCP servers across 16+ AI clients, with OAuth debugging and CI/CD gates.

Key features

  • Inspector: An interactive playground that sends the same prompt to several AI clients at once so you can call a tool, read the raw trace and compare how your MCP server appears in each client.
  • OAuth & Elicitation Debugger: Walks the full authorization handshake and shows the exact step where auth breaks, instead of leaving you to guess from a failed connection.
  • Cross-Client Testing: Covers 16+ major MCP clients and 170+ models, with a capability comparison matrix showing what each client actually supports.
  • Swarms: Generates agent personas with goals and behaviors, runs them through your server across multiple clients, and captures and scores every simulated session.
  • User Testing: Shares a sandboxed chatbox link with real testers, collects per-turn star or thumb ratings, and surfaces sentiment and usability findings.
  • Evaluation Suites: Durable scored test suites reporting pass rate, latency, token usage and tool-call counts per run, with suite health tracked over time.
  • CI/CD Actions: Runs the same suite on every pull request through GitHub Actions, the CLI or the SDK, so a failing check blocks the merge.
  • CLI and SDK: Run MCPJam as one terminal command or drive it programmatically from code, for local loops and automated pipelines alike.

Best for

  • Local MCP Development: Iterate on a server with npx @mcpjam/inspector and see tool behavior instantly, skipping the deploy-and-retry cycle.
  • Auth Troubleshooting: Trace a broken OAuth or elicitation flow to the specific failing step before customers hit it.
  • Release Gating: Wire an evaluation suite into CI so behavior regressions block a merge rather than reaching production.
  • Cross-Client Parity Checks: Verify a server behaves consistently in ChatGPT, Claude and Cursor, where client capabilities and prompting differ.
  • Pre-Launch User Research: Run persona swarms and invite real testers through a sandboxed link to find usability gaps before public release.
  • Enterprise Quality Standards: Apply one shared quality bar, RBAC and audit logging across every MCP server an organization ships.

APIs and SDKs for developer-first authentication, enabling passwordless and secure user sign-in across web and mobile.

Key features

  • APIs and SDKs: Official backend and frontend SDKs (Go, Android, iOS, JavaScript/React examples) to accelerate integration of authentication flows into applications and reduce implementation effort.
  • Magic Link Email Flows: Built-in endpoints and SDK helpers to generate and send magic link emails for passwordless login, with parameters for attributes like IP and metadata for security and analytics.
  • WebAuthn & FIDO Support: WebAuthn registration and verification surfaces to enable hardware-backed, phishing-resistant passwordless authentication for modern browsers and devices.
  • User Management & Search: Server-side APIs for searching, filtering, and managing user records (e.g., phone/email/WebAuthn verification status) at scale with parameters for queries and limits.
  • B2B Organization Management: Endpoints and SDK support for creating and managing organizations, organization slugs, and organization-scoped login/signup flows for multi-tenant or enterprise use cases.
  • Mobile SDK Integration: Mobile-first SDKs (Android, iOS) that simplify native authentication flows and integrate with the Stytch API for seamless mobile user experiences.
  • Developer Experience & Examples: Repository of example apps and demo projects (React, Next.js) and extensive SDKs to help teams prototype, test, and ship authentication quickly.
  • REST APIs for authentication and user management
  • Official backend SDKs (example: Go SDK at github.com/stytchauth/stytch-go/v16)
  • Official mobile SDKs for iOS and Android
  • Passwordless flows including Magic Links and email-based login
  • Phone/SMS-based authentication flows
  • WebAuthn/FIDO2 support for passkeys and hardware-backed auth
  • B2B features: organizations, invite/login-or-signup scoped to orgs
  • User search and filtering (email/phone/webauthn verified filters)
  • Example web integrations (React example using Vite)
  • Client initialization using project ID and secret API keys

Best for

  • Passwordless Consumer Login: Implement magic link or WebAuthn-based login flows to remove passwords and reduce friction for consumer-facing web or mobile apps.
  • Native Mobile Authentication: Integrate Stytch's Android and iOS SDKs to provide secure, native sign-in methods and simplify mobile onboarding and verification.
  • Enterprise/B2B Onboarding: Create and manage organizations, slugs, and organization-scoped login/signup flows for multi-tenant SaaS platforms or enterprise customers.
  • Secure User Management: Perform large-scale user searches and administrative actions (filter by email/phone/WebAuthn verification) for customer support and compliance workflows.
  • Modernize Legacy Auth: Replace legacy username/password systems with Stytch's passwordless and WebAuthn capabilities to improve security posture and reduce account takeover risk.
  • Prototype and Demo Auth Features: Use Stytch example apps and SDKs to rapidly prototype authentication workflows, test magic link/email flows, and validate UX before production rollout.
  • Replace passwords with passwordless email or SMS magic link login
  • Add passkey/WebAuthn support for strong, phishing-resistant auth
  • Implement multi-tenant/B2B organization sign-up and management
  • Build mobile-first authentication using iOS and Android SDKs
  • Integrate user search, verification status checks, and admin tooling via backend SDKs
