Available tools 5

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

carrier

carrier_record

Qualify a USDOT number and an as-of date: whether this archive can answer for them, what each source holds for the period, and what a purchased record could establish. It returns no row of the record. The answer says what the archive holds for the date, never what was true of the carrier. A filing on record is not coverage in force, and a source holding nothing is not a finding about the carrier unless the answer says the absence is provable.

carrier_record_by_docket

Qualify a docket number and an as-of date: whether this archive can answer for them, what each source holds for the period, and what a purchased record could establish. It returns no row of the record. The answer says what the archive holds for the date, never what was true of the carrier. A filing on record is not coverage in force, and a source holding nothing is not a finding about the carrier unless the answer says the absence is provable.

coverage

coverage

Return the read surface's coverage, its limits and how the record is bought.

specimen

specimen

Return one published specimen. A specimen is a sample with the carrier withheld, not an issued record.

verify

verify

Verify a Substradium fingerprint. The answer names neither the carrier nor the customer. The answer says what the archive holds for the date, never what was true of the carrier. A filing on record is not coverage in force, and a source holding nothing is not a finding about the carrier unless the answer says the absence is provable.

Carrier Records — questions

Answers built from our own checks of this server.

What can Carrier Records do?

It exposes 5 tools, read directly from the server on our last check. Among them: carrier_record, carrier_record_by_docket, coverage, specimen, verify. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Carrier Records working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 363 ms. The bar chart above shows every period we have measured.

How do I connect Carrier Records?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Carrier Records need an API key?

No. Carrier Records completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Carrier Records?

It answers our handshake in 363 ms on average, which is faster than 37% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
