## Quality 73/100 (new)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: estimate_us_duty (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); find_hts_code (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); lookup_us_duty_rate (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 561 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`: tool history recorded for 5 of the 7 days needed

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 3, about 561 tokens to load them all
- tool set hash: 77611d507e8f608f93f4e4bcd6a7dd5a
- badge: [![protogrid quality](https://protogrid.dev/badge/com.profitpather.tools/us-tariff-lookup.svg)](https://protogrid.dev/servers/com.profitpather.tools/us-tariff-lookup)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (3)

- `estimate_us_duty`: Applies the governing ad valorem rate for an HTS code to a customs value and returns the indicative duty, with the free-trade rate shown separately when the origin qualifies. It states plainly what is excluded rather than presenting a total that looks complete. Use it for a directional landed-cost figure, never as a customs declaration.
- `find_hts_code`: Search the official US Harmonized Tariff Schedule by plain-language product description and get back candidate HTS lines with their duty rates. Classification is the hard part of importing and the usual place a costly mistake is made, so this returns several candidates with their descriptions rather than pretending there is one obvious answer.
- `lookup_us_duty_rate`: Given a US HTS code, returns the duty rate that actually applies, resolving the common trap that rates sit on the 8-digit line while the 10-digit statistical lines underneath are blank and inherit. Optionally pass the country of origin to see whether a free-trade rate is available. Always reports what is excluded, because trade remedies such as Section 301 are not in this data and can dwarf the base rate.
