Anlyon alternative
1 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.

calculate_tariffCalculate the full stacked US import tariff rate for an HTS code from a specific origin country.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 Calculate the full stacked US import tariff rate for an HTS code from a specific origin country. Returns: base rate, each additional layer (China Section 301 matched by HTS line to Lists 1, 2, 3, 4A and the 2024 four-year-review increases, Section 232, and the 2026 Section 301 forced-labor tariff on 60 economies: 10% or 12.5% by origin, or a 10%/12.5% cap net of MFN for the EU, Taiwan, Japan, South Korea and Switzerland, in effect since 24 Jul 2026, FR Doc. 2026-15181, HTS 9903.05.20-9903.05.84), the total current rate, the date the data was checked, and notes naming each exemption or assumption (Section 232 goods, USMCA- or CAFTA-DR-qualifying entries, listed products). Also states when the Section 301 China product exclusions end, in both official wordings: through 11:59 p.m. EDT on November 9, 2026 (Federal Register, FR Doc. 2025-21671), which USTR's 26 Nov 2025 press release gives as "until November 10, 2026". Figures are estimates; IEEPA tariffs ended 20 Feb 2026 and are not included. Optionally computes dollar impact from annual import volume.

Why it is in this group
- The name "compare_origins" says "compare": a word for reading.
Description, as the server wrote it Compare the estimated US import tariff for ONE HTS code across several origin countries side by side (e.g. China vs Vietnam vs Mexico vs India), for sourcing and "China plus one" decisions. For each origin returns the total current rate, the layers that make it up (MFN base, Section 301 China, Section 232, 2026 Section 301 forced-labor tariff) and the rate after the Section 301 China exclusions end (through 11:59 p.m. EDT on 9 Nov 2026 per the Federal Register, FR Doc. 2025-21671; USTR's press release says until 10 Nov 2026), sorted lowest first, with the dollar duty when an annual import value is given. Estimates only; preferential rates (USMCA, FTAs) depend on rules of origin and are not assumed.
lookup_hts_codeFind the US HTS (Harmonized Tariff Schedule) code for a product, by plain-language product name or numeric prefix, from the official USITC schedule (19,856 10-digit codes).No findings
Why it is in this group
- The name "lookup_hts_code" says "lookup": a word for reading.
Description, as the server wrote it Find the US HTS (Harmonized Tariff Schedule) code for a product, by plain-language product name or numeric prefix, from the official USITC schedule (19,856 10-digit codes). Use this first whenever you have a product name rather than a code (e.g. "laptop", "wireless earbuds", "toys", "solar panels", "e-bike", "running shoes"), then pass a code to calculate_tariff or compare_origins. Everyday shopping words that a plain search of the schedule misses are mapped to the official heading that covers them (e.g. laptop -> 8471.30 "Portable automatic data processing machines"), and the answer names that heading. Otherwise descriptions are matched as one phrase; if a phrase matches nothing the tool retries single words and says which word it used. Returns up to 12 codes.
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

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

}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 tariffmonitor. Review it before you use it.
Pin
Keep the decision: fail CI when the tools change, follow every change, or show a badge.
