Overview

Description from the maker (original English)

License plate lookup for AI agents: plate messages and ALPR history via PlateQuery. OAuth 2.1.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

You need

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Works in Claude on the web, desktop and mobile:

  1. Open Settings → Connectors
  2. Press Add custom connector
  3. Paste the address below and press Add
  4. If it asks you to sign in, sign in with the maker
SettingsConnectors1+ Add2https://…3
https://api.platequery.com/mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "plate-api": {
      "url": "https://api.platequery.com/mcp"
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "plate-api": {
      "type": "http",
      "url": "https://api.platequery.com/mcp"
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

ChatGPT connects only to servers on the internet:

  1. Open ChatGPT on the web → Settings → Connectors (Apps)
  2. Press Create or Add (some plans need Developer mode under Advanced first)
  3. Paste the address below, give it a name and save
  4. If it asks you to sign in, sign in with the maker
SettingsConnectors1+ Create2https://…3

Menu names can differ slightly by plan and over time.

Your choice stays on this device in a cookie; no account needed.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is PlateQuery MCP — US License Plate & Vehicle Information safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

PlateQuery MCP — US License Plate & Vehicle Information

License plate lookup for AI agents, built on [PlateQuery](https://platequery.com/) — the license plate lookup site people use to notify vehicle owners, report bad driving, or flag illegal parking. This Model Context Protocol server lets an agent read those same messages for any U.S. license plate, plus public ALPR (automated license plate reader) sighting history from the Flock Safety camera network, by state or region.

  • Website: https://platequery.com/
  • API docs / pricing: https://api.platequery.com/
  • MCP endpoint: https://api.platequery.com/mcp (Streamable HTTP)
  • Registry listing: com.platequery/plate-api on the official MCP registry

This repository holds public documentation for the server. The implementation lives in PlateQuery's main application repository, which is closed-source.

Tools

ToolCostDescription
check_creditsFreeCheck your account's remaining credit balance. Doesn't count against the rate limit.
lookup_plate1 creditQuick summary for one plate: privacy status, the latest 3 messages (plus a total count), and a count of ALPR mentions, if any are public.
list_plate_messages1 creditFull, paginated list of messages posted about a plate.
list_plate_alpr_mentions1 creditFull, paginated ALPR search history for a plate, including the searching agency and source.
post_plate_messageFreePost a new message about a plate -- e.g. "reported for speeding" -- optionally with vehicle make/model/year/color and an approximate location. Requires the write scope. See Posting messages below.

A plate marked private by its owner returns zeroed messages/mentions to everyone except that owner. Free plan grants a starting credit balance on signup; additional credits are purchased in bulk packages — see api-settings for current pricing. Paid tools are rate-limited per account; call check_credits as often as you like to check balance without spending a credit.

Posting messages

post_plate_message is free but deliberately conservative, since it's the only tool that writes anything:

  • Requires a PlateQuery account with a confirmed email.
  • Rate-limited: 2 posts/minute, 10 posts/day, 3 posts/day about the same plate.
  • Not published immediately. Every post goes into the same moderation queue a website submission does -- it's invisible (and the plate's followers aren't notified) until a human moderator approves it.
  • vehicle_make/vehicle_model/vehicle_year/vehicle_color and location are all optional free text -- location should be an approximate description (e.g. "Hwy 37 near Los Altos, CA" or a cross-street), never precise GPS coordinates.

Authentication

The server is OAuth 2.1 only — no manual API keys. It supports PKCE and dynamic client registration (DCR), so a compliant MCP client (Claude, or any client following the MCP authorization spec) can connect by:

  1. Pointing at https://api.platequery.com/mcp.
  2. Following the WWW-Authenticate challenge to discover https://platequery.com as the authorization server (RFC 9728 protected resource metadata).
  3. Registering itself dynamically (RFC 7591) and running the standard Authorization Code + PKCE flow.
  4. Signing in with (or creating) a PlateQuery account when prompted.

No client secret or pre-issued API key is needed — sign-in happens in the browser the first time an agent connects.

Two scopes exist: read (the default -- covers every tool except post_plate_message) and write (required for post_plate_message, opt-in only). A client must explicitly request write at connect time to be able to post; an existing read-only connection can't post without reconnecting.

Adding it to an MCP client

Most MCP clients (including Claude) let you add a remote server by URL. Add https://api.platequery.com/mcp as a Streamable HTTP connector and follow the sign-in prompt on first use.
