Which integrations are available for this server?

Provides tools for interacting with an open ArcGIS Pro project, including reading layers and features, querying and editing data, applying symbology, working with layouts and bookmarks, running geoprocessing tools, and executing arbitrary arcpy code.

How do I use arcgis-pro-mcp-free?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@arcgis-pro-mcp-free List the layers in the current map" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

MCP Free Bridge for ArcGIS Pro

Versión en español: README.es.md

A free, local bridge between Model Context Protocol (MCP) and ArcGIS Pro 3.5 or newer: 68 commands (reading, geometry, editing, symbology, layouts, geoprocessing and arcpy code execution) that any MCP-capable assistant can use directly on your open project.

No paid licenses, no cloud: the Add-In listens on 127.0.0.1:PORT (your PC only) and the launcher exposes the 167 MCP tools.

Architecture

Assistant (opencode, Claude, ...)  <--stdio JSON-RPC-->  tcp_bridge.py
        <--TCP 127.0.0.1:PORT, length-prefixed JSON-->  Add-In (Pro)

Piece	What it is
`ArcGisProMcpFree.esriAddinX` (`package/`)	Compiled Add-In: 68 commands + manual control window (EN/ES)
`py-server/tcp_bridge.py`	MCP launcher: reuses the 167 tools from `arcgis-mcp-server`, swapping only the transport to TCP
`*.cs`, `Config.daml`	Add-In sources (C# .NET 8)
`tests/`	Maintainer verification suites

Related MCP server: CLI-Anything · ArcGIS Pro

Requirements

ArcGIS Pro 3.5 or newer (tested on 3.5.4; desktopVersion: 3.5 loads forward).
Python 3.12+ with pip install -r requirements.txt.
To compile the Add-In (optional): .NET 8 SDK.

Install (5 minutes)

1. Install the Add-In

Double-click package/ArcGisProMcpFree.esriAddinX — it installs itself. Or copy it to Documents\ArcGIS\AddIns\ArcGISPro\.

2. Install the MCP launcher — option A: uvx (no manual install)

"arcgis_mcp_addin": {
  "type": "local",
  "command": [
    "uvx",
    "--from",
    "git+https://github.com/IngKevinDavid/ArcGis-Pro-MCP-Free",
    "arcgis-pro-mcp-free"
  ],
  "environment": {}
}

uvx fetches the launcher from this repo on first use (the pinned tool wheel comes from the Release assets). Nothing to download by hand besides the Add-In.

2b. Option B: global Python

cd <repo>
py -m pip install -r requirements.txt   # vendored wheel, no venv needed

"arcgis_mcp_addin": {
  "type": "local",
  "command": [
    "C:\\Users\\YOU\\AppData\\Local\\Programs\\Python\\Python313\\python.exe",
    "PATH\\TO\\py-server\\tcp_bridge.py"
  ],
  "environment": {}
}

3. Port selection

Without PORT, everything uses port 5876. For another port (e.g. 8791): type it in the Add-In window and add "environment": {"PORT": "8791"} to the MCP entry (reload the client so it picks it up).

Use

Open your project in Pro. Nothing listens on its own: tab MCP Free Bridge → button MCP Free Bridge → Start (shows RUNNING 127.0.0.1:5876). The ribbon icon is red while stopped, green while running. UI in English, Español button switches to Spanish.
Use the tools from your assistant: list_layers, query_layer, run_gp_tool, label_layer, apply_graduated_symbology, geometry_area, create_feature, export_layout, ...
Arbitrary arcpy code via the run_gp_tool tool with the bundled ArcPyExec.pyt → ExecPython.
When done: Stop in the window.

MCP tools (167)

Coverage: 165 of 167 tools run against the Add-in — 68 dedicated commands plus client-side wrappers that delegate to the tested generic run_gp_tool. publish_web_layer and stage_service_definition need a staged server connection and answer a clean error until implemented.

Verify (maintainer)

$V = "py-server\.venv\Scripts\python.exe"
& $V tests\contract_check.py   # 67 raw checks over TCP
& $V tests\mcp_suite.py        # 15 checks through the real MCP path

Tests use ARCGIS_TEST_GDB (a file GDB with fixture data) and PORT; defaults run in the author's environment.

Troubleshooting

Symptom	Typical cause
No ribbon tab	`BlockAddins=1` policy at `HKCU\SOFTWARE\ESRI\ArcGISPro\Settings` → set it to `0`
`ConnectionRefused`	Bridge not started (window → Start) or `PORT` mismatch on both sides
Port busy on Start	Another process owns it; pick another port in the window
`allow_delete`	Destructive tools require explicit `"allow_delete": true` (safety)

Technical notes

Honest limits: no online portal (3 commands fail cleanly).
count_features counts the source and ignores definition queries (queries honor them).
Deleting a GDB in Explorer while Pro holds it leaves it locked; use the Delete tool with allow_delete.
