Carrier Records is a remote MCP server that gives an AI agent 5 tools, among them carrier_record, carrier_record_by_docket, coverage. It answers at https://substradium.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 5 of 5 times since 13 September 2026; the last check, on 19 October 2026, succeeded.
Dated motor-carrier records with receipts, verification, and specimens, from a records custodian.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
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 Inputs: as_of, usdot |
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 Inputs: as_of, docket |
coverage | Return the read surface's coverage, its limits and how the record is bought. |
specimen | Return one published specimen. A specimen is a sample with the carrier withheld, not an issued record. Inputs: name |
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 hold Inputs: fingerprint |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://substradium.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 13 September 2026. The tools are exactly what the server returned; nothing on this page
