Under the hood

Built on open standards

We didn't build a proprietary plugin system. We implemented every spec in the book so any compliant client works out of the box — today, tomorrow, and five years from now.

Model Context Protocol (MCP)

The open standard for connecting AI assistants to external tools. One protocol, universal compatibility.

Streamable HTTP Transport

Modern, bidirectional communication over standard HTTP. No WebSockets, no polling — just fast, reliable streaming.

OAuth 2.1 + PKCE (S256)

Industry-standard authentication with proof key exchange. Your credentials never touch the AI client.

Dynamic Client Registration

RFC 7591. Clients register themselves automatically — no manual API key setup, no configuration files.

RFC 9728 Discovery

Protected Resource Metadata lets clients auto-discover the auth server. Paste a URL and everything else is automatic.

RFC 8414 Authorization Server Metadata

Standard discovery for token endpoints, supported grant types, and PKCE methods. Full spec compliance.
