Quick start, Claude Desktop

Open claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/; Windows: %APPDATA%\Claude\) and add or merge in this block, then restart Claude Desktop:

{
  "mcpServers": {
    "urbankit-atlas": {
      "command": "npx",
      "args": ["-y", "@urbankitstudio/mcp-atlas"]
    }
  }
}

Claude Desktop launches the server via npx on startup. In a fresh conversation ask: "What urbankit-atlas tools do you have?", you'll see all four. Try "What's the parcel REST endpoint for Travis County, TX?"

The same config block works for Cursor and any other client that supports stdio MCP servers.

The 4 tools

The AI client discovers these via tools/list and calls them as needed during a conversation.

Example exchange

A real conversation with Claude Desktop after connecting the server:

User:   What's the parcel REST endpoint for Travis County, TX?

Claude: [calls get_parcel_endpoint({ state: "texas", county: "travis-county" })]

Tool:   {
          "url": "https://maps.traviscountytx.gov/arcgis/rest/services/GIS/TaxParcelQuery/MapServer/0",
          "searchFields": [
            { "name": "PROP_ID",      "searchable": true },
            { "name": "LEGAL_NAME",   "searchable": true },
            { "name": "SITUS_ADDR",   "searchable": true }
          ],
          "ownerField": "LEGAL_NAME",
          "sampleQuery": "...where PROP_ID='123456'"
        }

Claude: Travis County uses MapServer layer 0. To look up an owner, query
        the LEGAL_NAME field. Here's a ready URL for partial-match
        owner search. Let me know if you want me to run it.

The model chose get_parcel_endpoint, got back the verified ArcGIS URL, the owner field name, and a ready query, no manual tab-switching or ArcGIS convention knowledge required.

Also available: remote HTTP endpoint

Clients that connect to MCP servers by URL (no local subprocess) can point directly at https://urbankitstudio.com/api/mcp. It runs on Vercel and speaks JSON-RPC 2.0 over HTTP per the MCP 2025-06-18 spec. Six discovery tools remain public and read-only. Two key-gated actions perform the work: enrich_address for one owner/APN lookup and radius_owners for a capped radius mailing list.

Frequently asked questions

Production use

The MCP server is free and public for evaluation. Teams that need higher Parcel Data API rate limits, bulk county data delivered as JSON or CSV, the radius-notice tool with seats for staff, and an uptime SLA have a tier for that. Built for proptech, title and escrow, land-use law, and GIS consultancies.
