Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@CarrierScore MCP Server Check the CarrierScore risk rating for US DOT 1234567."
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
FMCSA motor-carrier risk intelligence for AI agents, over the Model Context Protocol.
CarrierScore answers "how risky is this carrier, and what was knowable about it on a given date?" for freight brokers and AI booking/dispatch agents. It builds longitudinal risk scores (0–100, higher = riskier) and timestamped carrier-selection evidence reports ("Montgomery files") from daily archives of public FMCSA / US DOT safety data: census, inspections, crashes, out-of-service orders, operating authority, and insurance filings.

No install needed — a hosted Streamable HTTP MCP endpoint is live:
https://mcp.carrierscore.io/mcpKeyless requests get a rate-limited free tier (lookups, scores, text evidence reports). Paid tiers add carrier-list monitoring, structured JSON evidence reports, and higher volume — see pricing. Paid tiers authenticate with an X-API-Key header (or CARRIERSCORE_API_KEY when self-hosting).

Tool | What it does |
| Carrier identity by US DOT number: legal name, DBA, operating status, FMCSA safety rating, fleet size, address, registration dates. Use first to confirm a DOT is real and matches the rate confirmation. |
| The CarrierScore risk score (0–100, higher = riskier) with full component breakdown, hard flags (active OOS order, no active insurance, reincarnated-carrier link), and data-sufficiency indicator. |
| Timestamped carrier-selection evidence report — the documented artifact a broker retains at the moment of booking (post Montgomery v. Caribe Transport II). Text format on the free tier; JSON on paid tiers. |
| Batch score summary + flags for up to 100 DOT numbers per call — screen candidates for a load or re-check an active roster. |

CarrierScore scores are computed statistical indicators built from public FMCSA data under a documented, transparent methodology (population percentiles plus hard flags). They are not safety fitness determinations, are not endorsed by FMCSA, and do not substitute for a carrier's official safety rating or your own judgment. Every score and evidence report embeds this disclaimer — retain it when storing or quoting results.
