Persado MCP Gateway
A production remote Model Context Protocol server operated by Persado at https://api.persado.com/mcp. Discovered by probing the API host: the RFC 9728 protected-resource document names the resource verbatim as "Persado MCP Gateway (Production)". Access is gated by OAuth 2.1 — authorization code with mandatory S256 PKCE, public clients, RFC 7591 dynamic client registration at https://api.persado.com/register, and an mcp:tools scope issued by the persado-portal Keycloak realm. A tools/list call returns HTTP 401 with a spec-correct WWW-Authenticate resource_metadata challenge, so the tool inventory is auth-gated and is deliberately not recorded. Persado does not document this server anywhere public.
