From the project READMEBiennial Update Sentinel
Is this US motor carrier's biennial MCS-150 update due, or already missed?
Every interstate motor carrier must refresh its MCS-150 every 24 months, by the last day of the month set by the last digit of its USDOT number, in odd or even years according to the next-to-last digit (49 CFR 390.19T). Missing it exposes the carrier to civil penalties and deactivation of its USDOT number.
For 1 to 10 USDOT numbers, this MCP server and HTTP API return: the last and next filing deadlines, the days left counted in the carrier's state time zone, the date of the last MCS-150 update on file, an overdue flag (true, false, or null when the rule or the data does not settle it), the exposure to deactivation, and the USDOT status. Source: the FMCSA Company Census File (data.transportation.gov), refreshed daily. It returns a regulatory status, never a score or a ranking of carriers.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
