# Stytch Connected Apps (slim)

> Turns a Stytch project into an OAuth 2.1 and OIDC authorisation server so agents and MCP clients can act for your users.

- Full: https://www.anchorterminal.com/tools/stytch-connected-apps.md (~6,600 tokens) · this version ~1,430 tokens · JSON https://www.anchorterminal.com/tools/stytch-connected-apps.json · canonical https://www.anchorterminal.com/tools/stytch-connected-apps
- Index: https://www.anchorterminal.com/llms.txt · API: https://www.anchorterminal.com/api/v1/index.json · Updated: 2026-10-04

**C · 60.8/100 · rank #241 of 452 · #6 in Agent auth & delegated access · not agent-ready · confidence medium**


Assessment: OAuth 2.1 authorisation server with DCR, CIMD and PKCE out of the box. No outbound token vault, so it can't hold your users' third-party tokens.

## Before you call it

1. Fetch `{project-domain}/.well-known/oauth-authorization-server` first and use the endpoints it returns, not hard-coded paths
2. Register with `token_endpoint_auth_method` none and PKCE S256 when the agent can't keep a secret
3. Expect a 401 with protected resource metadata from the MCP server, then register and authorise
4. Ask only for scopes the user's roles can grant, or the consent page will refuse them
5. Back off exponentially on a 429, since no Retry-After header is documented

## Connect

```bash
npm install stytch
```

```bash
curl -X POST https://api.stytch.com/v1/connected_apps/clients \
  -u "$STYTCH_PROJECT_ID:$STYTCH_SECRET" \
  -H "Content-Type: application/json" \
  -d '{"client_type":"third_party_public","client_name":"My agent","redirect_urls":["https://example.com/callback"]}'
```
