How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →

Endpoint Security83
  • The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
  • No authorisation is required to call this server. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation. See how to fix → View diagnostics → Partial
  • HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
  • The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
  • DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
Schema Quality & AI Usability65
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 1020 tokens (~340/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management77
  • Stability observed for 23 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
  • Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass

MCP tools · 3 exposed · ~743 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
classify_hts ~86

Find the US Harmonized Tariff Schedule classification for a product. Returns candidate HTS codes with their official descriptions and base duty rates. Use when the user wants the code itself rather than a cost. Not charged: it does not use a duty lookup.

landed_cost ~517

Calculate US import duty and landed cost estimates. Give hts_code when you know it and this returns the calculated base duty and trade actions (Section 301, Section 232, Section 338, AD/CVD and others), estimated duty, fees and import cost. When estimate_status is partial, part of the duty is undetermined (AD/CVD deposits, or a per-unit duty that needs a quantity) and the amounts are provisional; convey that the estimate is incomplete, and read duty_total_bound for whether the total is a minimum. Give product instead and it returns candidate HTS codes WITHOUT pricing, because the classification decides the duty and guessing it produces confidently wrong numbers: confirm the right code with the user, then call again with hts_code. The candidate step is not charged, and neither is the same lookup repeated within ten minutes.

policy_changes_since ~140

List US trade policy changes Gateway has published since a given date: new tariff actions, rate changes, effective dates and expirations, each with its official source. Also returns, under upcoming, earlier entries for changes announced or proposed but not yet in force. Use to answer "what changed recently" or "what is coming". Not charged: it does not use a duty lookup.

Install

How do I install the Gateway Lines Tariff MCP server?

Gateway Lines Tariff is a hosted endpoint at https://mcp.gatewaylines.com/, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

Common questions

What is the Gateway Lines Tariff MCP server?

Gateway Lines Tariff is an MCP server listed in the public MCP registry as com.gatewaylines/tariff. US import duty, HTS classification and tariff changes from the Gateway Lines tariff engine. This page covers its hosted endpoint (https://mcp.gatewaylines.com).

Is the Gateway Lines Tariff MCP server safe to use?

Gateway Lines Tariff scores 82 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the Gateway Lines Tariff MCP server expose?

Gateway Lines Tariff exposes 3 tools: landed_cost, classify_hts, policy_changes_since. Their descriptions and schemas cost roughly 743 tokens of context every time the server is loaded.

Does the Gateway Lines Tariff MCP server require authentication?

No. We connected to Gateway Lines Tariff without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the Gateway Lines Tariff MCP server still maintained?

Gateway Lines Tariff is still listed as active in the MCP registry. We last reached this channel on 6 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

What did VerifyMCP test on the Gateway Lines Tariff MCP server?

VerifyMCP ran 13 checks on Gateway Lines Tariff, covering TLS certificate, Authorization, HTTPS, HSTS header and 9 more. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
