Will my client connect?

Decided from what the probe found at the endpoint, and from what each client's own documentation says it can complete. Every row carries the day that documentation was read.

The authorization server advertises no S256 challenge method, which MCP's authorization spec requires — no compliant client has a method in common with it.

How to authenticate

Checked against the endpoint by our probe on 14 Oct 2026. These are the capabilities the server advertises, not a prediction about any particular client.

Scheme	OAuth
Issuer	https://codeatlas.com.br
Dynamic client registration	✓Advertised (RFC 7591)
Client ID Metadata Document	✕Not advertised
PKCE	✕None advertised MCP requires S256; a client that implements only that has no method in common with this server.
Grant types	client_credentials, urn:workos:agent-auth:grant-type:claim
Scopes	api:write
Protected-resource metadata	✓Published (RFC 9728)
Anonymous access	Handshake succeeds; 4 tools listable
Credentials demanded in prose	✕codeatlas_request_contact 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

warningTools needing credentials are listed without a challenge

1 of the 4 tools listed anonymously say in their own descriptions that they need an account or a key (codeatlas_request_contact), 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.

4 tools usable without signing in

The server exposes a public surface before authorization: codeatlas_list_services, codeatlas_get_service, codeatlas_search_services, codeatlas_request_contact.
