Playable MCP Server
Hosted Model Context Protocol endpoint served from the Playable web property and advertised through RFC 9728 protected-resource metadata at playable.com/.well-known/oauth-protected-resource. Requires OAuth 2.0 authorization-code + PKCE (S256) with the `mcp` scope; an anonymous tools/list call returns 401 mcp_unauthorized, so the tool set and input schemas are not enumerable without credentials.
