Anlyon alternative
3 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.

Changes things 3Claude Code: ask
check_fitDoes this part fit that machine?No findings
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.
Description, as the server wrote it Does this part fit that machine? Returns a verdict with the rule id and version that decided it, or the missing fields. Example: {"subject_id":"e3d-v6-brass-0-4","target_id":"prusa-mk4s"}
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false

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.
Description, as the server wrote it Availability and price per merchant, re-verified live when the data is over an hour old. Example: {"product_id":"prusa-mk4s","merchant_id":"prusa3d"}
Annotations the server declares

report_issueFlag a wrong spec, price or fit verdict.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it Flag a wrong spec, price or fit verdict. Reports never edit facts; two independent reports mark a fact disputed. Example: {"entity_type":"product","entity_id":"prusa-mk4s","field":"nozzle_thread","claim":"MK4S uses the Nextruder thread"}
Annotations the server declares
- readOnlyHint: false

compareSide-by-side spec table with offers and the fields that differ.Reads private dataNo findings
Why it is in this group
- The name "compare" says "compare": a word for reading.
What it can reach
- private-dataThe description's first sentence says "table": it reads databases.
Description, as the server wrote it Side-by-side spec table with offers and the fields that differ. Pass 2-10 product_ids, or a category with filters. Example: {"product_ids":["e3d-v6-brass-0-4","bondtech-cht-0-4"]}

Why it is in this group
- The name "get_product" says "get": a word for reading.
Description, as the server wrote it Full specs with per-field confidence and source, every offer with verified time, 30/90-day price range. Example: {"product_id":"prusa-mk4s"}
Annotations the server declares

Why it is in this group
- The name "search_products" says "search": a word for reading.

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 untrusted-input or outbound.
- Reads private data1
- 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__3d-printing__search_products",
"mcp__3d-printing__get_product",
"mcp__3d-printing__compare"
],
"ask": [
"mcp__3d-printing__check_fit",
"mcp__3d-printing__check_stock",
"mcp__3d-printing__report_issue"
],
"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 3d-printing. 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.
