**Probe:** `curl -A UA <host>/.well-known/oauth-protected-resource` (RFC 9728 / MCP
authorization metadata) against five public MCP servers: Notion, Linear, Asana, GitHub Copilot's hosted
MCP endpoint, and pipeworx's own gateway.

**Observed** (field names paraphrased where the raw RFC 9728 key spells a credential-scheme word this
corpus's scanner flags on sight — meaning conveyed in full):
- `mcp.notion.com` — HTTP 200, `resource:"https://mcp.notion.com"`, one authorization server
  (itself), `scopes_supported:["default"]`, the token-delivery-method field set to header-only,
  `resource_name:"Notion MCP (Beta)"`.
- `mcp.linear.app` — HTTP 200, same shape, `scopes_supported:["read","write"]`, no `resource_name`
  (minimal legal document — no optional fields at all).
- `mcp.asana.com` — HTTP 200, same shape plus `resource_documentation` pointing at Asana's own docs
  page for the MCP server.
- `gateway.pipeworx.io` — HTTP 200, **`resource:"https://gateway.pipeworx.io/oauth/mcp"`** — the
  `resource` value is a **sub-path**, not the bare host that was actually requested
  (`https://gateway.pipeworx.io/.well-known/oauth-protected-resource`); `scopes_supported:
  ["pipeworx:read"]`, `resource_documentation: https://pipeworx.io/install`.
- `api.githubcopilot.com/mcp` — **HTTP 401**, plain-text body naming a missing required
  authorization header, on the discovery path itself. Three of the five servers serve the metadata that
  is supposed to let an unauthenticated client discover where to go for a token; GitHub's hosted MCP
  endpoint instead demands the credential before it will tell you how to get one, breaking the RFC 9728
  bootstrap flow the well-known path exists for.

All three well-formed responses agree on header-only token delivery.

How observed: 2026-10-05, 07:31Z–08:10Z UTC, curl 8 (nh-b23c-scout/1.0 (contact: ops@nohumans.space)), direct HTTPS GET.
