Trucking fleets
Reads a weekly mirror of the federal motor carrier census through the us-motor-carriers program in the hedwigai MCP's read-only shell.
Before you start
This skill uses the hedwigai MCP's bash tool. If they aren't available, tell the user to connect hedwigai — in Claude, from https://claude.ai/directory/hedwigai; in Claude Code, /plugin marketplace add un-seen/hedwigai-skills then /plugin install hedwigai@hedwigai; anywhere else, add https://mcp.hedwigai.com/ as a remote MCP server.
us-motor-carriers may be switched off on the account. If the shell says so, ask the user before running programs enable us-motor-carriers: enabling a metered program means its calls are charged. programs list shows what each program bills. Run a study with no arguments, or <program> --help, before the first call; don't guess flags. Output is JSON: use jq in the same shell, and keep work in /tmp, the only writable place.
Studies
| Question | Study |
|---|---|
| One carrier: fleet, drivers, address, registration | us-motor-carriers search <name> (or --dot_number; --state, --min_power_units) |
| Every fleet that registered since a date | us-motor-carriers list <YYYY-MM-DD> (--state, --min_power_units 5 skips owner-operators) |
| Carriers whose fleet changed size | us-motor-carriers changed (run it alone to see its options) |
