Tools you get
Endpoint checked 2026-10-09: https://haulroll-api.cybermaxtools.com/mcp answered an MCP initialize (protocol 2025-06-18) and tools/list with 3 tools, all marked read-only. No key was used and no tool was called.
| Tool | What it does | Required inputs |
|---|---|---|
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. | 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. | carriers |
new_carriers | Carriers FMCSA added in the last N days (active only), filterable by state, cargo, hazmat, interstate and for-hire. Company facts only. | none |
Test the endpoint from a terminal
This lists the tools without a key and without calling any of them:
curl -s https://haulroll-api.cybermaxtools.com/mcp \
-H 'content-type: application/json' \
-H 'accept: application/json, text/event-stream' \
-d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'If it does not work
- Custom connectors connect from Anthropic's cloud, not your computer; our servers are public, so no allowlisting is needed.
- Free plans can add one custom connector.
- To change the URL or header, remove the connector and add it again.
- The free tier has a daily limit (see the pricing line above); a paid key raises it.
