PDF Spec (PDF Agent Stack) MCP server

PDF SPEC MCP Server

日本語版 README はこちら

An MCP (Model Context Protocol) server that provides structured access to ISO 32000 (PDF) specification documents. Enables LLMs to navigate, search, and analyze PDF specifications through well-defined tools.

[!IMPORTANT]

This is a specification reference, not a rule engine.

It retrieves and structures the text of ISO 32000 — clauses, tables, definitions, and

shall/should/may requirements. It does not examine a PDF file, and it cannot tell

you whether a document conforms to anything. Conformance verdicts come from

pdf-verify-mcp

(validateconformance / evaluatepolicy).

The distinction matters because three different things get conflated:

declaration — a label the file wrote about itself ("I am PDF/A" in the metadata). Writing it is not evidence /

conformance — whether the file actually meets the standard. There is no way to prove it in full; you can only find where it breaks the rules /

validation — what a validator (veraPDF and the like) reports against the checks it implements. A pass means "this inspection did not fail", not "the file conforms to the standard".

Reading a shall here tells you what the standard requires — not whether your file meets it.

A search that returns nothing means "cannot answer", not "no such requirement."

ISO 19005 (PDF/A) and ETSI PAdES are outside this corpus; see list_specs → coverage.gaps.

What each PDF family server does — and does not do

[!IMPORTANT]

PDF specification files are NOT included in this package.

You must obtain the PDF specification documents separately and place them in a local directory.
