Model Context Protocol
No blockquote summary.
0 sections, 364 links, no Optional section.
Ora's cached score: 69, grade C, scanned 16 October 2026.
The parse
modelcontextprotocol.io lists 364 links: 364 point at modelcontextprotocol.io or a relative path, 0 point elsewhere. The hosts it links most: modelcontextprotocol.io (364).
The file has no H2 sections.
Grade against the llmstxt.org structure
The file passes 4 of 6 checks and fails 2: has a blockquote summary under the h1; has at least one h2 section that lists links. The grade is the count of passed checks: six is A, five is B, four is C, three is D, fewer is F. It measures structure only. Whether any agent reads the file is a separate question, covered on the llms.txt reference.
| Check | Result | Detail |
|---|---|---|
| Starts with an H1 naming the site or project | Pass | H1: Model Context Protocol |
| Has a blockquote summary under the H1 | Fail | No blockquote summary before the first H2. |
| Has at least one H2 section that lists links | Fail | 0 H2 sections, 0 with links. |
| At least 80 percent of links point at the same site | Pass | 364 of 364 links stay on modelcontextprotocol.io (100 percent). |
| Under 100 KB | Pass | 50527 bytes as served. |
| Plain markdown, no HTML | Pass | No HTML document markers in the body. |
Ora's cached score
Ora's cached report for modelcontextprotocol.io gives it 69 of 100, grade C, scanned on 16 October 2026. Its Access layer, which holds the read-layer checks below, scored 41 of 58 check points. Read from GET ora.ai/api/score/modelcontextprotocol.io on 5 November 2026. The score is Ora's, not this site's, and the structure grade above is a different measure: it grades the llms.txt file against the llmstxt.org proposal, while Ora's score covers the whole site. Ora's report for modelcontextprotocol.io has every layer.

Linking and the companion file
The home page of modelcontextprotocol.io links the file in its HTML. Ora's lab found (2026-10-19) that 86 percent of llms.txt fetches by agents arrived through a link, so an unlinked file is mostly a file nobody opens. An llms-full.txt is served at the same root.
How it compares
At 49 KB the file is larger than 91 percent of the 2,529 plain-text llms.txt files in this edition, and its 364 links put it ahead of 94 percent of them on link count. The home page declares a Mintlify generator. Size bucket: 10 to 50 KB. Tranco rank 8,985. Category: Standard.
Why it is in the index: Long link list with no H2 sections at all. Owner as listed: Model Context Protocol.
