Help with connecting Proofwork to Claude, ChatGPT or another MCP client, with your account, or with your data.

We aim to reply within two business days. When you write, include the AI assistant you are using (Claude, ChatGPT, other), the approximate time of the problem, and any error text you saw. Please do not send passwords, API keys or access tokens.
Troubleshooting
The connector will not connect, or sign-in fails
- Check the server URL exactly matches the one on the
connector documentation, including the
/mcppath. - Leave any optional OAuth client ID / secret fields empty. Sign-in is set up automatically.
- Allow pop-ups for
proofworklabs.comif you sign in with Google. - Remove the connector, add it again, and sign in once more. This clears a stale authorization.
I am asked to sign in again
Access is granted for a limited time and your assistant will ask you to sign in again when it expires. Signing in again does not affect your account or usage.
The assistant does not use the Proofwork tools
Make sure the connector is enabled for the conversation (in the tools or connectors menu of your assistant), then ask directly, for example: "Use Proofwork to classify seamless copper tubes under the HTS."
A tool returns an error
Tool errors say what was wrong with the request, for example a heading that is not four digits or a code that does not exist in the current HTS revision. If you see an error that does not explain itself, email us the text and the time it happened.
A classification looks wrong
Proofwork returns reference data (tariff text and CBP ruling precedents) and your AI assistant makes the selection. Results are decision support, not a binding ruling. Send us the product description and the code you expected, and we will review it.
Disconnect Proofwork
Claude
Open Customize → Connectors, select Proofwork, and choose Disconnect or Remove.
ChatGPT
Open chatgpt.com/plugins, select Proofwork, and disconnect or remove it.
Disconnecting stops your assistant from calling Proofwork. It does not delete your Proofwork account; see below for that.
Delete your account and data
- Email [email protected] from the address on your Proofwork account with the subject "Delete my account".
- If you have a paid subscription, cancel it first from your account page, or ask us to cancel it in the same email.
- We confirm the request by reply and delete your account, API keys and usage records within 30 days. Billing records we are legally required to keep are retained for that purpose only.
You can also ask for a copy of your data or a correction at the same address. What we hold is described in our privacy policy. The product descriptions you send to Proofwork tools are not stored, so there is nothing to delete for them.
Billing
Manage or cancel a subscription, download invoices and update your payment method from your account page. Payments are processed by Stripe. For anything you cannot do there, email [email protected].
