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.

How to authenticate
Checked against the endpoint by our probe on 18 Oct 2026. These are the capabilities the server advertises, not a prediction about any particular client.
| Scheme | OAuth |
|---|---|
| Issuer | https://envoisms.ma |
| Dynamic client registration | ✕Not advertised A client that cannot register itself needs credentials issued out of band before it can begin the flow. |
| 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, authorization_code, urn:ietf:params:oauth:grant-type:api-key |
| Scopes | sms:send, sms:read, verify:send, verify:check, account:read |
| Protected-resource metadata | ✓Published (RFC 9728) |
| Anonymous access | Handshake succeeds; 18 tools listable |
| Credentials demanded in prose | ✕lookup_number, get_pricing 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
2 of the 18 tools listed anonymously say in their own descriptions that they need an account or a key (lookup_number, get_pricing), 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.
The server exposes a public surface before authorization: send_sms, send_bulk_sms, send_whatsapp_template, get_message_status, list_messages, get_balance, create_topup, send_otp, verify_otp, list_campaigns, list_contacts, get_analytics, ops_pulse, ops_route_quality, ops_monitoring, lookup_number, list_sender_ids, get_pricing.
