CarrierScore MCP Server

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.

Website: carrierscore.io · Agent docs: carrierscore.io/llms.txt

No install needed — a hosted Streamable HTTP MCP endpoint is live:

https://mcp.carrierscore.io/mcp

Keyless 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).

Tools

ToolWhat it does
carrier_lookupCarrier 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.
carrier_scoreThe 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.
montgomery_fileTimestamped 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.
monitor_carriersBatch score summary + flags for up to 100 DOT numbers per call — screen candidates for a load or re-check an active roster.

Self-hosting

The server in this repo is a thin Streamable HTTP client over the CarrierScore REST API (https://api.carrierscore.io).

npm install
npm run build
CARRIERSCORE_API_URL=https://api.carrierscore.io npm start
# MCP endpoint: POST http://127.0.0.1:8322/mcp

Environment variables:

VariableDefaultPurpose
CARRIERSCORE_API_URLhttp://127.0.0.1:8321Base URL of the CarrierScore REST API
CARRIERSCORE_API_KEY(unset)Optional API key for paid tiers; unset = rate-limited free tier
PORT8322Port for the MCP HTTP endpoint (POST /mcp)

Disclaimer

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.
