`md_dmv_vehicle_registrations`

Pack: md-dmv · Endpoint: https://gateway.pipeworx.io/md-dmv/mcp

Count vehicles registered in Maryland by county for a given month, from Maryland Motor Vehicle Administration (MVA) data published monthly since 2020. Returns each county’s registered-vehicle count plus the genuine statewide total for that month and each county’s share of it, so it answers “how many vehicles are registered in Montgomery County Maryland”, “which Maryland county has the most registered vehicles”, “how many cars are registered in Maryland”, and month-over-month trend questions via the month argument. Counts the whole registered fleet of every fuel type; for the electric and plug-in hybrid slice of it use md_dmv_ev_adoption.

Parameters

Name	Type	Required	Description
`county`	string	no	Maryland county or Baltimore City, e.g. “Montgomery”, “Prince George’s”, “Baltimore City”. Apostrophes and periods are optional.
`month`	string	no	Month as YYYY/MM, e.g. “2026/06”. Defaults to the most recent month Maryland has published. The series starts at 2020/07.
`limit`	number,string	no	Max counties to return (default 30, max 200). Maryland publishes 25 rows per month, so the default returns them all.
