Mo Dmv MCP Server

@pipeworx/mo-dmv

Missouri DMV data: the Department of Revenue's driver and motor-vehicle license offices, with hours, the contract agent who runs each one, and the upcoming dates it will be closed. Keyless.

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

What Missouri calls its DMV

Missouri has no "DMV". Driver licensing and vehicle registration happen at license offices run by the Missouri Department of Revenue, and — unusually — the state does not staff them itself. All 176 offices are contracted out to private agents, which is why agent, officemanager and contractmanager are real columns here and have no analogue in another state's office file. Hours, phone numbers and closures follow the agent, not the state.

Tools

Filters: city, name, zip, limit.

Auth

None. data.mo.gov is a public Socrata portal and the public rate limit is ample without an app token.

Why this is the freshest DMV endpoint in any state

Missouri refreshes this dataset daily — as_of came back as the current date on every verification call. That is what makes additional_days_closed worth returning: the closure list is current enough to plan a visit around, which no other state's office file supports.

Entries can be whole days (11/27/2026) or partial (6/22/2026 Closed Partial Day PM), and they sit ahead of the separately published holidays_closed list rather than duplicating it.

Gotchas worth knowing

These are live-verified behaviours, not guesses:

• county is empty on all 176 rows. The column exists upstream and is null everywhere, so the tool passes it through as null rather than inventing one. Filter by city instead.
• type is 1MV on every office. Every Missouri license office does both driver licensing and motor vehicle work, so the code carries no discriminating information today; it is surfaced in office_type in case the state ever splits the categories.
• Some ZIPs are stored as ZIP+4 with no hyphen (658075187). The zip filter is a prefix match, so a five-digit ZIP still matches those rows.
• url is a Facebook page when it exists. Many contract agents run a Facebook page instead of a website, and that is the only per-office link the state publishes.
• as_of is fetched concurrently with the data, not after it. Socrata throttles unauthenticated bursts and the metadata helper does not retry, so a sequential call intermittently lost the refresh date — on a file whose whole value is a daily refresh.

Quick Start

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

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

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/mo-dmv/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, 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"
    }
  }
}

Both URLs reach the same gateway and the same 1476+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:

ask_pipeworx({ question: "your question about Mo Dmv data" })

The gateway picks the right tool and fills the arguments automatically.
