2 of these tools change something. Run those as governed actions.
Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.
Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
- outboundThe input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
Description, as the server wrote it Downloads one PDF from a public http or https link and reports the structure that screen readers use: whether the file is tagged, whether it has a document title and a language, how many images have no text description and on which pages, and reading-order signals (pages with columns are flagged for a person to check). Also reports the page count and which pages look scanned or contain tables. Use when the user gives a link to a PDF on a public website and asks about its accessibility or screen-reader structure. Does not open files behind a login, does not change the file, and does not say whether the file meets PDF/UA, WCAG or any law.

Description, as the server wrote it For one to five links to PDFs on public websites, counts pages by type and returns a price estimate from CyberNative AI LLC's published Terms for two options: an accessible web page made from the PDF (USD 6 per page with tables or scanned pages, USD 4 per other page), and, where the file qualifies, the same PDF with tags added (USD 4 per page, minimum USD 100 per order). Lists files and pages that are not converted, such as fillable forms, maps and drawings, with the reason. The estimate is not binding and nothing is ordered by calling this tool; the price is confirmed by email before any work. Use when the user asks what it would cost to have these PDFs made accessible.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
Exfil surface
Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.
No private-data, untrusted-input, outbound path in this server alone: no tool is tagged private-data.
- Reads private data0
- Reads files, mail, messages, databases, secrets, calendars or repositories.
- Reads text others write2
- Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
- Can send data out2
- Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.
Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.
Findings
Matches of fixed checks, with the text they matched.
No check matched anything in these tool definitions. That is not a safety guarantee.
History
Changes to its tool definitions and to its remote endpoint, newest first.
No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.
Install
Pinned to version 0.1.0. Values in angle brackets are yours to fill in.

Claude Code permissions
Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.
{
"permissions": {
"allow": [],
"ask": [
"mcp__pdf-check__check_public_pdf",
"mcp__pdf-check__quote_fix"
],
"deny": []
}
}Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as pdf-check. Review it before you use it.
Capability tags behind 2 rules
- mcp__pdf-check__check_public_pdf untrusted-input, outbound
- mcp__pdf-check__quote_fix untrusted-input, outbound
Pin
Keep the decision: fail CI when the tools change, follow every change, or show a badge.
Pin in CI
Fail a build when the tools you reviewed are not the tools the server serves today.
