MCP connector
Tarifflo hosts a remote MCP connector. There is nothing to install: add one URL to your MCP client and sign in.
Connect
The connector speaks MCP over Streamable HTTP at this URL. In Claude, open Settings → Connectors → Add custom connector and paste it; other MCP clients take the same URL.
https://app.tarifflo.com/mcpAuthenticate
Use either credential:
- OAuth. Connect with no credential and the client is challenged to sign in. A Tarifflo sign-in page opens; approve access and pick the organization. Claude.ai, Claude Desktop and ChatGPT work this way.
- API key. Send
Authorization: Bearer tflo_...orX-API-Key: tflo_.... For a client that cannot set headers, append?api_key=tflo_...to the URL. See Authentication.
claude mcp add --transport http tarifflo https://app.tarifflo.com/mcp \
--header "Authorization: Bearer $TARIFFLO_API_KEY"A tool appears only when the credential carries its scope. The filing, sorting, configuration and entry-editing tools need the filing scope.
What it can do
The connector serves 51 tools in five groups.
Async lookups
Classify a product, rate an HTS code, find an ECCN or a country of origin, then wait for the answer or watch a pipeline run.

Pick an organization, upload one entry's documents, answer the questions the pipeline asks, and hand back a review link.

Place the documents of a multi-entry upload that the pipeline could not match to an entry.

List, read, create and update the pipeline configurations an upload runs under, and the filers they transmit as.

Open an entry summary, read what is left, set fields, manage lines, PGAs and tariff rows, and validate.

The connector prepares entries but never transmits them to CBP. A filing job ends with a review link; a person opens it and submits.
