No outbound token vault, so it can't hold your users' third-party tokens.\n\n**Vercel Connect.** Provider refresh tokens stay with Vercel, and code receives short-lived tokens tied to a project and environment through one call with a public OpenAPI definition. Vercel's SLA excludes its APIs, the status page records 94 minutes of elevated Connect errors on 10 September 2026, and the only SDK is TypeScript.\n\n## Before you call either\n\n### Stytch Connected Apps\n\n1. Fetch `{project-domain}/.well-known/oauth-authorization-server` first and use the endpoints it returns, not hard-coded paths\n2. Register with `token_endpoint_auth_method` none and PKCE S256 when the agent can't keep a secret\n3. Expect a 401 with protected resource metadata from the MCP server, then register and authorise\n4. Ask only for scopes the user's roles can grant, or the consent page will refuse them\n5. Back off exponentially on a 429, since no Retry-After header is documented\n\n### Vercel Connect\n\n1. Call `getToken` at request time and don't store the result. The SDK caches up to 100 tokens in process and refreshes them 30 seconds before expiry\n2. Pass `scopes` on every request. Since SDK 1.0.0 an omitted `scopes` defaults to `['*']`, the connector's default scopes\n3. Catch `UserAuthorizationRequiredError`, call `startAuthorization` and send the user to the returned URL. Consent needs a person in a browser\n4. Outside Vercel, pass a Vercel access token as `vercelToken`. It can request only the app subject or its own user, not another user\n5. On a 429 wait one minute for the window to reset. Limits are 200 token requests a minute per team\n\n## Questions\n\n### Which is better for AI agents, Stytch Connected Apps or Vercel Connect?\n\nVercel Connect scores 68.8 (B) on agent readiness against Stytch Connected Apps's 60.8 (C), and leads in 6 of 7 scored categories. Stytch Connected Apps leads on reliability.\n\n### Do Stytch Connected Apps and Vercel Connect need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Stytch Connected Apps and Vercel Connect without installing anything?\n\nYes. Stytch Connected Apps has a hosted endpoint at https://api.stytch.com and Vercel Connect at https://api.vercel.com.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/stytch-connected-apps-vs-vercel-connect.json, and with the fewest tokens: https://www.anchorterminal.com/compare/stytch-connected-apps-vs-vercel-connect.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"stytch-connected-apps\", \"b\": \"vercel-connect\"}`.
