ArcGIS Pro MCP — Claude plugin

Drive a live, open ArcGIS Pro session from Claude using arcpy. Claude can list layers, describe datasets, run geoprocessing, and inspect the current project — executing directly against whatever project you have open in Pro.

Because it runs inside your open Pro session, everything happens locally on your Windows machine. This plugin is a distribution wrapper; the actual arcpy work still requires ArcGIS Pro running in front of you.

Prerequisites (required — this will not work without them)

• Windows (ArcGIS Pro is Windows-only)

• ArcGIS Pro installed with a valid license

• Claude Code or the Claude desktop / Cowork app on the same machine

• A one-time mcp package install into Pro's Python (handled by install.ps1)

If you don't have ArcGIS Pro installed and licensed, this plugin cannot do anything.

What you get

An MCP server (arcgis-pro) exposing:

Plus a bundled skill (arcgis-pro-workflow) that teaches Claude the per-session listener startup, credit-gating etiquette, and releasing Pro's UI when done.

Install

1. Install the plugin

From a local folder (e.g. this OneDrive copy):

/plugin marketplace add "C:\Users\<you>\OneDrive - Econsult Solutions Inc\Documents\Claude\plugins\arcgis-pro-mcp"
/plugin install arcgis-pro-mcp@arcgis-pro-mcp-dev

Then restart Claude Code / the desktop app so the MCP server loads.

In the Claude desktop / Cowork app you can also add the marketplace folder through the plugin UI instead of the slash command.

2. One-time environment setup

The MCP server runs under Pro's Python and needs the mcp package there. Run:

powershell -ExecutionPolicy Bypass -File .\install.ps1

This finds arcgispro-py3\python.exe, installs mcp into it, and prints the exact listener line to use each session. If your Pro is on a non-standard path, update the command field in .claude-plugin/plugin.json to the path the script reports.

Using it (every session)

1. Open your project in ArcGIS Pro.

2. In Pro's Python window (View → Python), paste this self-locating snippet. It finds pro_listener.py wherever Cowork / Claude Desktop installed the plugin — you don't need to know the path (it differs per machine and per install):

   import glob, os
   _hits = sorted(
       glob.glob(os.path.join(os.environ["APPDATA"], "Claude", "**", "pro_listener.py"), recursive=True),
       key=os.path.getmtime, reverse=True)
   if not _hits:
       raise SystemExit("pro_listener.py not found. Is the arcgis-pro-mcp plugin installed?")
   print("Starting listener from:", _hits[0])
   exec(open(_hits[0]).read())

   The Python window will show "listener ready" and then appear busy — that's expected; the pump is running.

3. Ask Claude to do GIS work ("what layers are in my map?", "describe the parcels layer", "reproject X to Y").

4. Claude calls listener_stop() when finished to free Pro's UI. Re-run the snippet next time.

Notes on credits

execute_arcpy refuses Esri credit-consuming functions (geocoding, EnrichLayer, network solves, agolservices, drive-time areas, etc.). Those must go through execute_arcpy_credit with confirm_credit=True, which Claude sets only after you explicitly approve the credit cost.

Troubleshooting

Sharing with your organization

To let coworkers install with one command, put this folder in a GitHub repo and have them run:

/plugin marketplace add your-org/arcgis-pro-mcp
/plugin install arcgis-pro-mcp@arcgis-pro-mcp-dev

Each coworker still needs the prerequisites above (Pro + license) and must run install.ps1 once. You can also pre-wire the marketplace for a team via extraKnownMarketplaces in a shared .claude/settings.json.
