mcp-arcgis-fairfax
Fairfax County GIS — Fairfax County, Virginia open geospatial data (ArcGIS).
Part of Pipeworx — an MCP gateway connecting AI agents to 1000+ live data sources.
Tools
| Tool | Description |
|---|---|
search_datasets | Search Fairfax County GIS open geospatial datasets (parcels, zoning, public safety & planning) by keyword. Returns each dataset's name, summary, record_count, owner/org, and its Feature Service url — pass that url to query_layer / layer_info. |
query_layer | Query an ArcGIS Feature Service / Map Service layer by its url (from search_datasets). SQL-like where, comma-separated out_fields, order_by, limit, offset. Returns attribute rows (and geometry). Use where="1=1" + out_fields="*" to sample. |
layer_info | Get an ArcGIS Feature/Map Service layer's schema by url: fields (name + type), geometry type, total record count, and capabilities. |
Quick Start
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"arcgis-fairfax": {
"url": "https://gateway.pipeworx.io/arcgis-fairfax/mcp"
}
}
}
Or connect to the full Pipeworx gateway for access to all 1000+ data sources:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}
Using with ask_pipeworx
Instead of calling tools directly, you can ask questions in plain English:
ask_pipeworx({ question: "your question about Arcgis Fairfax data" })
The gateway picks the right tool and fills the arguments automatically.
