Questions
What counts as an MCP tool call?
Each step in a classification workflow is one call. A typical HTS classification uses ~5 calls (identify heading, select subheading, select leaf code, verify, browse). So 1,000 free calls is roughly 200 full classifications.
Do I need a separate AI subscription?
Proofwork runs inside your existing LLM workspace via the open MCP standard. You need your own LLM subscription — Proofwork provides the domain expertise as MCP tools, not the AI itself. Currently supported by Claude and ChatGPT, with more clients adopting MCP regularly.
How many team members can I add?
Unlimited. Proofwork subscriptions are per-organization, not per-seat. Invite your entire trade compliance team at no extra cost.
What skills are included?
All certified skill servers are included in every plan. Currently: HTS tariff classification. Coming soon: AD/CVD screening, landed cost analysis, FTA qualification, and more.
Can I cancel anytime?
Yes. Cancel from your account page. You'll retain access until the end of your billing period.
