Tx Dmv MCP server

@pipeworx/tx-dmv

Texas DMV (TxDMV) MCP — statewide vehicle, pickup and motorcycle registration totals by fiscal year, from TxDMV's own published series.

Part of Pipeworx — an MCP gateway connecting AI agents to 1476+ live data sources.

Tools

for a fiscal year, split into passenger cars, pickup trucks of one ton or less and motorcycles, each with its share of the fleet. Answers "how many vehicles are registered in Texas", "how many motorcycles are registered in Texas", and growth across years.

Grain and vintage — read this before quoting a number

Two things about this dataset trip people up, so both are reported on every response:

no county, city or ZIP breakdown in this series, and no make/model/fuel split. Passing county, zip, make, modelyear or fueltype returns { found: false, reason: "grainunavailable" } with a hint rather than silently ignoring the argument. For a ZIP-level fleet breakdown, cadmvvehicleregistrations covers California at ZIP × make × model-year × fuel.

1. Statewide only. TxDMV publishes one row per fiscal year for the whole state. There is

fiscal years 2001 through 2021 and recent years are simply absent. asof carries the refresh date, coversfiscalyears the span, and a note says so in words. Asking for fiscalyear="2024" returns fiscalyearunavailable rather than an empty row list.

1. The series stops at FY2021. TxDMV last refreshed it on 2023-03-06, so it covers

totalvehicles is only set when a single fiscal year is requested, because that row genuinely is the whole Texas fleet for that year. Rows from different fiscal years are not** summed: they are cumulative snapshots of largely the same vehicles, so a sum would double-count every car that stayed registered.

Verified live 2026-07-29: FY2001 totalallvehicles_registered = 17,906,116; FY2021 = 25,236,442.

The three ofallvehicles columns are fractions of 1 (0.5831), not percentages; the pack converts them to percentages. fiscalyear is stored as text, so it is filtered with a string equality and ordered as a string — which is safe for four-digit years.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "tx-dmv": {
      "url": "https://gateway.pipeworx.io/tx-dmv/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/tx-dmv/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — askpipeworx, discovertools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}
