Checked against the endpoint by our probe on 24 Aug 2026. These are the capabilities the server advertises, not a prediction about any particular client.
| Scheme | OAuth |
|---|---|
| Issuer | https://mcp.squirrelscan.com |
| Dynamic client registration | ✓Advertised (RFC 7591) |
| Client ID Metadata Document | ✓Supported A client identifies itself by a URL to its own metadata, so no registration step is required. |
| PKCE | ✓S256 |
| Grant types | authorization_code, refresh_token |
| Scopes | audits:read, audits:write, credits:read, org:read, keys:write |
| Protected-resource metadata | ✓Published (RFC 9728) |
| Anonymous access | Handshake succeeds; 18 tools listable |
| Credentials demanded in prose | ✕create_api_key These tools are listed anonymously and their own descriptions ask for an account or key, but no challenge is issued — so a client has nothing to act on and the refusal arrives as a tool error. |
What the probe found
1 of the 18 tools listed anonymously say in their own descriptions that they need an account or a key (create_api_key), but the endpoint issued no WWW-Authenticate challenge. The requirement is stated only in prose, so a call reaches the tool and comes back as a tool error instead of an authorization step.
A cross-origin preflight came back without Access-Control-Allow-Origin, so the endpoint is reachable from native clients only — code running in a web page is stopped by the browser before a request is ever sent.
The server exposes a public surface before authorization: run_audit, get_audit_status, list_audits, list_websites, add_website, delete_website, delete_websites, get_report, list_issues, get_issue, comment_on_issue, list_rules, get_rule, whoami, get_credit_balance, list_credit_transactions, create_api_key, send_feedback.
