## MCP tools (6)

### `ca_dmv_vehicle_registrations` (~341 tokens)

Count vehicles registered in California from official DMV data, broken down by ZIP code, make, model year, fuel type or light/heavy duty. Each row is a count of registered vehicles from the California DMV "Vehicle Fuel Type Count by Zip Code" file, with annual snapshots back to 2019, so it answers "how many vehicles are registered in ZIP 90210", "how many Toyotas are registered in California", or "how many 2024-model-year vehicles are on California roads". For electric-vehicle share of the fleet use ca_dmv_ev_adoption; for a DMV office address use ca_dmv_offices.

Input parameters:

- `duty` (string): Vehicle weight class: "Light", "Heavy" or "Unk".
- `fuel_type` (string): Fuel/drivetrain; plain words are mapped to California's labels, e.g. "electric", "diesel", "gas", "hybrid", "plug-in hybrid", "hydrogen".
- `group_by` (string): Breakdown dimension: fuel (default), zip, make, model_year, duty.
- `limit` (number|string): Max rows to return (default 25, max 200).
- `make` (string): Vehicle make, matched as a substring, e.g. "TESLA", "FORD".
- `model_year` (string): Four-digit model year, e.g. "2024".
- `year` (string): Snapshot year, 2019–2026. Defaults to 2026 (the most recent).
- `zip` (string): Five-digit California ZIP code, e.g. "90210".

### `ca_dmv_ev_adoption` (~278 tokens)

Measure electric-vehicle adoption in California from DMV registration counts: how many battery-electric and plug-in hybrid vehicles are registered in a ZIP code or statewide, and what share of all registered vehicles that represents. Returns the full fuel mix with a plug-in share and an electrified share (which also counts conventional hybrids and hydrogen), or a breakdown of plug-in vehicles by make, ZIP or model year. Answers "EV share in ZIP 94002", "which ZIP codes in California have the most EVs", "how many Teslas are registered in California", and trend questions via the year argument (snapshots back to 2019).

Input parameters:

- `group_by` (string): fuel (default) returns the whole mix plus EV share; zip, make or model_year return plug-in counts by that dimension.
- `limit` (number|string): Max rows to return (default 25, max 200).
- `make` (string): Vehicle make, matched as a substring, e.g. "TESLA", "RIVIAN".
- `model_year` (string): Four-digit model year, e.g. "2025".
- `year` (string): Snapshot year, 2019–2026. Defaults to 2026.
- `zip` (string): Five-digit California ZIP code, e.g. "94002".

### `ca_dmv_offices` (~239 tokens)

Find California DMV field offices with street address, per-day opening hours, coordinates and the services each office actually performs (behind-the-wheel retest, duplicate title, ID cards, self-service terminals, CDL medical and more). Answers "DMV office in Sacramento", "which California DMV near San Jose does driving tests", or "DMV offices in ZIP 95814". Covers all 187 field offices from the DMV's own directory. For live wait times, California publishes none — nc_dmv_wait_times and or_dmv_wait_times are the only state feeds that exist.

Input parameters:

- `city` (string): City name, matched as a substring, e.g. "Sacramento", "San Jose".
- `limit` (number|string): Max offices to return (default 50, max 200).
- `name` (string): Office-name substring, e.g. "Express", "Commercial".
- `service` (string): Require a service, e.g. "dl retest", "duplicate title", "id cards", "self service terminals".
- `zip` (string): Five-digit ZIP code, e.g. "95814".

### `ca_dmv_forms` (~165 tokens)

Search the official California DMV forms catalog by topic and get each form's name, its REG/DL/BOAT form number, and the page to download it from. Answers "which California DMV form transfers a title", "CA DMV form for a duplicate registration", "form to report the sale of a vehicle", or a lookup by number like "REG 227". Results follow the DMV site's own relevance ranking, so a broad phrase can surface a vessel form alongside the vehicle one.

Input parameters:

- `limit` (number|string): Max forms to return (default 10, max 50).
- `query` (string, required): What the form is for, e.g. "title transfer", "duplicate registration", "change of address", or a form number like "REG 227".

### `ca_dmv_insurance_lookup` (~118 tokens)

Look up an auto insurer's five-digit NAIC code from the California DMV insurance-carrier list by company name. California requires the NAIC number when reporting insurance for a registered vehicle, so this answers "NAIC code for State Farm", "what is Geico's NAIC number", or "insurer codes matching Progressive". The list is California's; NAIC codes themselves are national.

Input parameters:

- `insurer` (string, required): Insurance company name or fragment, e.g. "State Farm", "Geico", "Progressive".

### `ca_dmv_driver_licenses` (~195 tokens)

Count driver licenses outstanding in California by county of residence, as an annual series from 2008 onward, with the statewide total and the statewide count of DMV ID cards. Answers "how many licensed drivers are in Los Angeles County", "which California county has the most driver licenses", or how a county's licensed-driver count has changed over time. Counts people holding a license, which is a different question from how many vehicles are registered — for that use ca_dmv_vehicle_registrations.

Input parameters:

- `county` (string): County name, matched as a substring, e.g. "Los Angeles", "Alameda".
- `limit` (number|string): Max counties to return (default 30, max 60).
- `year` (string): Four-digit year from 2008 to the latest published (2024 as of October 2026), e.g. "2024". Defaults to the most recent.

## Common questions

### What is the Ca Dmv MCP server?

Ca Dmv is an MCP server listed in the public MCP registry as io.github.pipeworx-io/ca-dmv. California DMV MCP, registered vehicles and EV adoption by ZIP code, field offices, the official… This page covers its npm package (@pipeworx/mcp-ca-dmv).

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

Ca Dmv scores 82 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 Ca Dmv MCP server expose?

Ca Dmv exposes 6 tools: ca_dmv_vehicle_registrations, ca_dmv_ev_adoption, ca_dmv_offices, ca_dmv_forms, ca_dmv_insurance_lookup, ca_dmv_driver_licenses. Their descriptions and schemas cost roughly 1,336 tokens of context every time the server is loaded.

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

Ca 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 Ca Dmv MCP server under?

Ca 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 Ca Dmv MCP server?

VerifyMCP ran 16 checks on Ca 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.
