## 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)

## MCP tools (2)

### `wa_dmv_ev_population` (~480 tokens)

Count electric vehicles currently registered in Washington State, from the Department of Licensing (Washington DMV) VIN-level Electric Vehicle Population file — one row per registered vehicle, so these are fleet counts rather than sales or transactions. Breaks down by county, city, ZIP code, make, model, model year, legislative district, electric utility, or vehicle type, and separates battery-electric (BEV) from plug-in hybrid (PHEV). Reports average and median electric range and clean-alternative-fuel-vehicle eligibility. Answers "how many EVs are registered in Washington", "how many Teslas are in King County", "EV count by ZIP in Seattle", "BEV versus PHEV split in Washington", and "which Washington legislative district has the most electric vehicles".

Input parameters:

- `city` (string): City name in plain mixed case, e.g. "Seattle", "Bellevue", "Tacoma".
- `county` (string): Washington county in plain mixed case, e.g. "King", "Pierce", "Snohomish", "Spokane".
- `ev_type` (string): Drivetrain: "BEV" or "battery electric" for Battery Electric Vehicle (BEV), "PHEV" or "plug-in hybrid" for Plug-in Hybrid Electric Vehicle (PHEV).
- `group_by` (string): Breakdown dimension: county, city, zip, make, model, model_year, ev_type, cafv_type, legislative_district, electric_utility. Defaults to county.
- `legislative_district` (string): Washington legislative district number, e.g. "44".
- `limit` (number|string): Max rows to return (default 25, max 200). Raise it to 39 to cover every Washington county.
- `make` (string): Vehicle make, upper case in the source and matched as a substring, e.g. "TESLA", "CHEVROLET", "RIVIAN".
- `model` (string): Model name, upper case in the source and matched as a substring, e.g. "MODEL 3", "BOLT EV", "LEAF".
- `model_year` (string): Four-digit model year, e.g. "2025".
- `zip` (string): Five-digit ZIP code, e.g. "98052".

### `wa_dmv_registration_transactions` (~474 tokens)

Count Washington State vehicle registration transactions — original registrations and renewals processed by the Department of Licensing (Washington DMV) — for one fiscal year or one calendar month, broken down by county of the registered owner, county where the transaction happened, fuel type, use class, or month. Answers "how many vehicle registrations did King County process in fiscal 2026", "monthly registration volume in Washington", "diesel registration transactions by county", and "which Washington counties process the most registrations". Each transaction is an event, so a county with 1.9 million transactions in a year has far fewer vehicles than that; for the size of Washington's registered electric fleet use wa_dmv_ev_population.

Input parameters:

- `county` (string): County of the registered owner, plain mixed case, e.g. "King", "Pierce", "Spokane".
- `fuel_type` (string): Fuel; plain words are mapped to the published labels, e.g. "gas" → Gasoline, "flex" → Flex Fuel/Gasoline, "cng" → Compressed Natural Gas. Published labels: Gasoline, Unpowered, Diesel, Flex Fuel/Gaso…
- `group_by` (string): Breakdown dimension: county, transaction_county, fuel, use_class, month, fiscal_year. Defaults to county.
- `limit` (number|string): Max rows to return (default 25, max 200). Raise it to 39 to cover every Washington county.
- `month` (string): A single calendar month as YYYY-MM, e.g. "2026-05". Takes precedence over `year`.
- `transaction_county` (string): County where the transaction was processed, plain mixed case, e.g. "King". Differs from `county` when an owner registers away from home.
- `use_class` (string): Use class as published, matched as a substring, e.g. "Passenger Car", "Truck", "Trailer", "Motorcycle".
- `year` (string): Four-digit state fiscal year from 2017 onward, e.g. "2026". Defaults to the latest year published.

## Common questions

### What is the Wa Dmv MCP server?

Wa Dmv is an MCP server listed in the public MCP registry as io.github.pipeworx-io/wa-dmv. Washington State DMV MCP, the Department of Licensing's VIN-level electric-vehicle population… This page covers its npm package (@pipeworx/mcp-wa-dmv).

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

Wa 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 Wa Dmv MCP server expose?

Wa Dmv exposes 2 tools: wa_dmv_ev_population, wa_dmv_registration_transactions. Their descriptions and schemas cost roughly 954 tokens of context every time the server is loaded.

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

Wa 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.

### What licence is the Wa Dmv MCP server under?

Wa Dmv declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the Wa Dmv MCP server?

VerifyMCP ran 16 checks on Wa Dmv, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
