# MCP authorization: Authorization (draft)

> GAMMA-Ray v0.0.155 (beta, for review; every rating is experimental). One line item of Model Context Protocol, Authorization (draft) (mcp.09): its text, its place in the source, the indicators that cite it and the evidence that reaches it.
> Page: https://gamma-ray.sgit.ai/provisions/mcp.09/ · Source: data/provisions.json


Provision mcp.09 · Model Context Protocol, Authorization (draft) · requirement

> Authorization MUST be included in every HTTP request from client to server.

The text is as taken from the source. **In the source:** [https://modelcontextprotocol.io/specification/draft/basic/authorization#token-requirements](https://modelcontextprotocol.io/specification/draft/basic/authorization#token-requirements) (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 |
|---|---|---|---|
| [`I28`](../../questions/index.md#I28) | Its tokens are bound to the service they were issued for and are not passed on | part: partly evidenced | Asserted in the mapping by gamma-ray@web-summit.dinis; the written basis is not recorded yet. |

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.

## The evidence that reaches it

No published card reaches this provision yet. That is not a no.

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.09` ([how](../../fact-ray/well-known/index.md)). A company that already assesses itself against MCP authorization can reuse that work.
