With Anlyon
Decide which of this server's tools your agent can use.
- Anlyon lists the tools and adopts none.
- Each tool you adopt gets approvals and receipts.
- Your agent never holds the key.
A tool your agent calls directly is not routed through Anlyon and is not governed by it. anlyon.dev only lists and labels, and these labels are the same either way.
What the NonToxicFinder MCP server can do
The NonToxicFinder MCP server is published by the GitHub account timmasterson. It has 4 tools. Every one of them only reads: going by their definitions, none of them creates, changes, sends or deletes anything.
None of its tools reads private data, brings in text other people write, or sends data out.
None of the fixed checks matched anything in its tool definitions. That is not a safety guarantee.
Its remote endpoint lists its tools without sign-in.
Last scanned Nov 12, 2026, version 1.0.0.
Tools
Grouped by what each tool does, most consequential first. Open one for its reasons and full description; descriptions are the publisher's own words.
4 tools
Only reads 4Show 4 read-only tools
get_articleGet a NonToxicFinder article summary by slug: its title, excerpt, frequently asked questions and the products it features, in the order the article shows them.No findings
Why it is in this group
- The name "get_article" says "get": a word for reading.
Description, as the server wrote it Get a NonToxicFinder article summary by slug: its title, excerpt, frequently asked questions and the products it features, in the order the article shows them. Link people to the url given in each result and never construct a retailer link. Say "last read on <date>" for a certification. Say "brand-level" when evidence_scope is "brand". Ratings are scores, not certifications.

get_productGet one published product by slug or ASIN, with every claim shown honestly (including lapsed, unverifiable and stale ones) and the history of reads behind each claim.No findings

- The name "get_product" says "get": a word for reading.
Description, as the server wrote it Get one published product by slug or ASIN, with every claim shown honestly (including lapsed, unverifiable and stale ones) and the history of reads behind each claim. Give exactly one of slug or asin. Link people to the url given in each result and never construct a retailer link. Say "last read on <date>" for a certification. Say "brand-level" when evidence_scope is "brand". Ratings are scores, not certifications.

search_productsFind products that hold a third-party certification NonToxicFinder has checked against the certifier's registry or the maker's page.No findings
Why it is in this group
- The name "search_products" says "search": a word for reading.
Description, as the server wrote it Find products that hold a third-party certification NonToxicFinder has checked against the certifier's registry or the maker's page. Only products with a current, recently read certification are returned. An empty list means no certified match in this data, not that none exists. Link people to the url given in each result and never construct a retailer link. Say "last read on <date>" for a certification. Say "brand-level" when evidence_scope is "brand". Ratings are scores, not certifications.

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 or untrusted-input or outbound.
- Reads private data0
- Reads files, mail, messages, databases, secrets, calendars or repositories.
- Reads text others write0
- Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
- Can send data out0
- 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.

Claude Code permissions
Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

"permissions": {
"allow": [

"mcp__nontoxicfinder__get_article"
],
"ask": [],
"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 nontoxicfinder. Review it before you use it.
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.
