At a glance

Type: MCP server
Works with: ArcGIS
How it connects: Drives a running copy of the tool
Access: Can modify models
Tool versions: ArcGIS Pro 3.3 (reference), 3.6 and 3.7 tested, 3.4 community-reported; 3.1–3.2 unsupported
Operating systems: Windows
Needs a ArcGIS licence: Yes
Transport: Local (stdio)
AI clients documented: Claude Desktop, Cursor
Licence: Apache-2.0
Language: Python

What it can do

Covers .aprx map and layer management, geodatabase and field work, overlays, projections, raster and DEM analysis, layouts and PDF export.
Runs network analysis (routes, service areas, closest facility) and spatial statistics such as kernel density, hot spots and Moran's I, using Spatial and Network extension licences.
Restricts file access to folders you list, and refuses ten destructive tools unless the call includes an explicit confirm flag.
Runs each ArcPy job in its own worker process so a crash in Esri's native code doesn't take down the server.

Limitations

Needs Windows, a licensed ArcGIS Pro, and a cloned ArcGIS Pro Python environment set up with the package's setup command.
Works on project and geodatabase files through ArcPy rather than inside the open ArcGIS Pro window.
ArcGIS Pro releases with Python older than 3.11 can't run it.
