## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.

## MCP tools (2)

### `md_dmv_vehicle_registrations` (~252 tokens)

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.

Input parameters:

- `county` (string): Maryland county or Baltimore City, e.g. "Montgomery", "Prince George's", "Baltimore City". Apostrophes and periods are optional.
- `limit` (number|string): Max counties to return (default 30, max 200). Maryland publishes 25 rows per month, so the default returns them all.
- `month` (string): Month as YYYY/MM, e.g. "2026/06". Defaults to the most recent month Maryland has published. The series starts at 2020/07.

### `md_dmv_ev_adoption` (~337 tokens)

Measure electric-vehicle adoption in Maryland from Maryland MVA registration counts: how many battery-electric and plug-in hybrid vehicles are registered in a county or a ZIP code each month, split by fuel category, with a statewide Maryland total for context. Answers "how many EVs are registered in Montgomery County Maryland", "EV registrations in ZIP 20852", "which Maryland county has the most electric vehicles", "which Maryland ZIP codes have the most EVs", and EV growth over time via the `month` argument (monthly since 2020). Pass `zip` or group_by="zip" for the ZIP-level file, otherwise results come back by county. For Maryland's whole registered fleet across every fuel type use md_dmv_vehicle_registrations.

Input parameters:

- `county` (string): Maryland county or Baltimore City, e.g. "Montgomery", "Prince George's". Apostrophes are optional. Results are flagged in_maryland because this file also carries out-of-state counties of residence.
- `group_by` (string): Breakdown dimension: "county" (default) or "zip". Passing `zip` implies group_by="zip".
- `limit` (number|string): Max counties or ZIP codes to return (default 30, max 500).
- `month` (string): Month as YYYY/MM, e.g. "2026/06". Defaults to the most recent month Maryland has published. The series starts at 2020/07.
- `zip` (string): Five-digit ZIP code, e.g. "20852". Supplying this reads the ZIP-level file instead of the county file.

### Is the Md Dmv MCP server safe to use?

Md Dmv scores 81 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Md Dmv MCP server expose?

Md Dmv exposes 2 tools: md_dmv_vehicle_registrations, md_dmv_ev_adoption. Their descriptions and schemas cost roughly 589 tokens of context every time the server is loaded.

### Is the Md Dmv MCP server still maintained?

Md Dmv is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
