Overview

AI-generated overview

Looks up US motor carriers, brokers and freight forwarders in public FMCSA data, returning registration, authority, insurance and safety details.

What you can do
  • Search carriers, brokers and forwarders by company name in FMCSA census data, with up to 10 matches showing USDOT number, location and status
  • Retrieve one company's record by USDOT, MC, FF or MX number, including census registration, operating authority, current insurance filings and a 24-month roadside safety summary
  • List changes to a carrier's public census fields over the last 90 days, such as name, status, fleet size, MCS-150 date and dockets
  • Attach a CarrierTrail link to each answer
When to use it
Useful when you need to vet a US trucking company, broker or freight forwarder before booking or contracting, confirm operating authority and insurance, or check whether a carrier's registration details changed recently.
Requirements
Remote streamable HTTP endpoint at carriertrail.com; no packages, environment variables or headers declared. Free use is limited per day.
Before you install
Free usage is capped per day, so heavy querying may hit a limit. Answers include CarrierTrail links and data comes from public FMCSA records, which may lag behind actual filings.

Installation

In SourceWeft

  1. Open CarrierTrail in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.carriertrail%2Fmcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Add this to your client's mcpServers config.

83% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
