MCP Integration

ARIA provides two MCP (Model Context Protocol) servers for AI agent identity operations.

Two MCP Servers

| Server | URL | Auth | Operations | |--------|-----|------|-----------| | ARIACORE MCP | core.aria.bar/mcp | OAuth 2.1 + DPoP | Register, update, revoke | | ARIAAPI MCP | api.aria.bar/mcp | None (public) | Resolve, verify, check status |

Both use Streamable HTTP transport (not SSE).
