Overview

Description from the maker (original English)

FMCSA motor-carrier risk scores, monitoring, and carrier-selection evidence reports for AI agents.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

Common questions

Is Carrierscore safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: GitHub, Desktop Commander, Cloudflare MCP

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

Hosted endpoint (recommended)

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

Tool	What it does
`carrier_lookup`	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.
`carrier_score`	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.
`montgomery_file`	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.
`monitor_carriers`	Batch 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:

Variable	Default	Purpose
`CARRIERSCORE_API_URL`	`http://127.0.0.1:8321`	Base URL of the CarrierScore REST API
`CARRIERSCORE_API_KEY`	(unset)	Optional API key for paid tiers; unset = rate-limited free tier
`PORT`	`8322`	Port 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.
