Tools

Tool	What it does	Effect	Inputs (* required)
`vet_carriers`	Verdict for 1-25 US motor carriers by USDOT or MC/MX/FF number: USDOT status and age, operating authority, liability insurance on file vs required, out-of-service orders, 24-month inspections (driver/vehicle OOS rates vs national) and crashes, with flags. Riskiest first.	read-only, calls public sources on the internet, never destructive	`carriers`*
`carrier_alerts`	FMCSA events in the last N days for up to 25 carriers: out-of-service orders, authority suspension notices and status changes, insurance cancellations. Empty = nothing new.	read-only, calls public sources on the internet, never destructive	`carriers`*, `days`
`new_carriers`	Carriers FMCSA added in the last N days (active only), filterable by state, cargo, hazmat, interstate and for-hire. Company facts only.	read-only, calls public sources on the internet, never destructive	`state`, `days`, `cargo`, `hazmat`, `interstate`, `forHire`, `limit`

Security and data handling

Your tool arguments are used only to answer that call. They are not saved to a database, shared, sold or used for training.
To make repeat lookups fast, some servers keep the public answer to a lookup in Cloudflare's edge cache for up to 7 days (most for 1 hour or less). It holds the public result, not who asked.
Free tier: a per-day counter keyed by a SHA-256 hash of your IP address and the date (in a Cloudflare Durable Object). The raw IP is not stored.
Paid key: the key is checked with the payment provider (Stripe; Polar for older keys) and the result is cached for 10 minutes; usage is counted per key per month.
No accounts, cookies or tracking on the MCP endpoint. Errors may appear in Cloudflare's short-lived Worker logs.
Every tool is read-only: it looks up public data and returns it. No tool writes, deletes, sends messages or spends money.
