> GAMMA-Ray v0.0.155 (beta, for review; every rating is experimental). One line item of Model Context Protocol, Authorization (draft) (mcp.01): its text, its place in the source, the indicators that cite it and the evidence that reaches it.

Provision mcp.01 · Model Context Protocol, Authorization (draft) · requirement

> MCP servers MUST implement OAuth 2.0 Protected Resource Metadata (RFC 9728).

The text is as taken from the source. **In the source:** [https://modelcontextprotocol.io/specification/draft/basic/authorization#overview](https://modelcontextprotocol.io/specification/draft/basic/authorization#overview) (the section of the specification that holds the requirement (its opening words were found there); linked 2026-11-10). The instrument: [Model Context Protocol, Authorization (draft)](../../instruments/index.md), the project's; requirements quoted with the source; read 2026-11-09.

## Who cites it

| Indicator | The fact it asks for | Kind of link | The assertion |
|---|---|---|---|
| [`I24`](../../questions/index.md#I24) | Its authorisation is published as metadata that anyone can read | same: evidenced | Asserted in the mapping by gamma-ray@web-summit.dinis; the written basis is not recorded yet. |
| [`S3`](../../questions/index.md#S3) | It is machine-readable for agents: it publishes an llms.txt, an AGENTS.md, an API description or an agent card | part: partly evidenced | The requirement is published resource metadata; an agent card or API description is published metadata of the same kind, though not this document. Asserted by gamma-ray@web-summit.dinis, 2026-11-10; weak: one reader, unchecked. |
| [`S4`](../../questions/index.md#S4) | It exposes an agent interface: a published MCP server, an agent card, or an API documented for agents to call | part: partly evidenced | The requirement applies to MCP servers; a product that publishes one is a subject of it. Publishing the server is not evidence that the metadata is implemented. Asserted by gamma-ray@web-summit.dinis, 2026-11-10; weak: one reader, unchecked. |

A link is our assertion, not the instrument's. "Same" carries the evidence to the provision in full. "Part" marks the provision as partly evidenced: the fact is one piece of what it asks. "Negation" points the other way.

Touched never means complies.

## Answer it directly

A company can answer this line item itself, in its own file at `/.well-known/fact-ray.json`, with the node `gamma-ray:provision/mcp.01` ([how](../../fact-ray/well-known/index.md)). A company that already assesses itself against MCP authorization can reuse that work.
