Halyard MCP HTTP API

Halyard's MCP server advertises OAuth 2.1 with Dynamic Client Registration. MCP clients can self-register automatically against the authorization-server metadata via the registration_endpoint at https://api.usehalyard.ai/oauth/register, then send the user through browser consent at the install guide / authorization endpoint. The protected resource metadata is published at https://mcp.usehalyard.ai/.well-known/oauth-protected-resource, and supported scopes include read, write, input_request, and session.
