UrbanKit Atlas — US County Parcel ArcGIS REST

The first parcel/GIS MCP server. Gives AI assistants direct access to 152 verified US county parcel ArcGIS REST endpoints across 50 states — for owner-name and APN (parcel number) lookup, property due diligence, and GIS automation. No API key required — all data is public county GIS.

Why it exists

Every county exposes its parcel service with different field names and URL conventions. This server hides that: ask for a county and get back its exact endpoint, its real owner/taxpayer field name, and a ready-to-fire query URL — so the model never needs to know ArcGIS REST conventions.

Tools

• list_counties — list every covered county (optionally filtered by state)
• find_county — resolve a county by name or FIPS code to its parcel service
• get_parcel_endpoint — get the full ArcGIS REST query URL for a county
• build_owner_query — build a case-insensitive owner-name search using the county's actual field names

Install

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

Or run directly: npx -y @urbankitstudio/mcp-atlas

Example

"Find the parcel endpoint for Denver County, Colorado and search for owner 'SMITH'."

The server returns Denver's ArcGIS REST URL, identifies the owner field, and hands back a ready-to-run query.
