One model everywhere
OAuth-protected MCP and REST operations, and the web application, invoke the same oRPC procedures and validation schemas.
Precise permissions
Authorize an OAuth connection, review its exact scopes and resources, and revoke it without copying a credential between apps.
Safe mutation semantics
Expected versions prevent one edit from silently overwriting another.
Structured discovery
The OpenAPI contract, MCP server card, documentation MCP, and agent-readable site files are public. Private product operations require OAuth.
