# QGISMCP - QGIS Model Context Protocol Integration QGISMCP connects [QGIS](https://qgis.org/) to [Claude AI](https://claude.ai/chat) through the [Model Context Protocol (MCP)](https://modelcontextprotocol.io/docs/getting-started/intro), allowing Claude to directly interact with and control QGIS. This integration enables prompt assisted project creation, layer loading, code execution and more. This project is strongly based on the [BlenderMCP](https://github.com/ahujasid/blender-mcp/tree/main) project by [Siddharth Ahuja](https://x.com/sidahuj) ## Features - **Two-way communication**: Connect Claude AI to QGIS through a socket-based server. - **Project manipulation**: Create, load and save projects in QGIS. - **Layer manipulation**: Add and remove vector or raster layers to a project. - **Execute processing**: Execute processing algorithms ([Processing Toolbox](https://docs.qgis.org/3.40/en/docs/user_manual/processing/toolbox.html)). - **Code execution**: Run arbitrary Python code in QGIS from Claude. Very powerful, but also be very cautious using this tool. ## Components The system consists of two main components: 1. **[QGIS plugin](/qgis_mcp_plugin/)**: A QGIS plugin that creates a socket server within QGIS to receive and execute commands. 2. **[MCP Server](/src/qgis_mcp/qgis_mcp_server.py)**: A Python server that implements the Model Context Protocol and connects to the QGIS plugin. ## Installation ### Prerequisites - QGIS 3.X (only tested on 3.22) - Claude desktop - Python 3.10 or newer - uv package manager: If you're on Mac, please install uv as ```bash brew install uv ``` On Windows Powershell ```bash powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex" ``` Otherwise installation instructions are on their website: [Install uv](https://docs.astral.sh/uv/getting-started/installation/) **⚠️ Do not proceed before installing UV** ### Download code Download this repo to your computer. You can clone it with: ```bash git clone git@github.com:jjsantos01/qgis_mcp.git ``` ### QGIS plugin You need to copy the folder [qgis_mcp_plugin](/qgis_mcp_plugin/) and its content on your QGIS profile plugins folder. You can get your profile folder in QGIS going to menu `Settings` -> `User profiles` -> `Open active profile folder` Then, go to `Python/plugins` and paste the folder `qgis_mcp_plugin`. > On a Windows machine the plugins folder is usually located at: `C:\Users\USER\AppData\Roaming\QGIS\QGIS3\profiles\default\python\plugins` and on MacOS: `~/Library/Application\ Support/QGIS/QGIS3/profiles/default/python/plugins` Then close QGIS and open it again. Go to the menu option `Plugins` > `Installing and Managing Plugins`, select the `All` tab and search for "QGIS MCP", then mark the QGIS MCP checkbox. ### Claude for Desktop Integration Go to `Claude` > `Settings` > `Developer` > `Edit Config` > `claude_desktop_config.json` to include the following: > If you can't find the "Developers tab" or the `claude_desktop_config.json` look at this [documentation](https://modelcontextprotocol.io/quickstart/user#2-add-the-filesystem-mcp-server). ```json { "mcpServers": { "qgis": { "command": "uv", "args": [ "--directory", "/ABSOLUTE/PATH/TO/PARENT/REPO/FOLDER/qgis_mcp/src/qgis_mcp", "run", "qgis_mcp_server.py" ] } } } ``` ## Usage ### Starting the Connection 1. In QGIS, go to `plugins` > `QGIS MCP` > `QGIS MCP`  2. Click "Start Server"  ### Using with Claude Once the config file has been set on Claude, and the server is running on QGIS, you will see a hammer icon with tools for the QGIS MCP.  #### Tools - `ping` - Simple ping command to check server connectivity - `get_qgis_info` - Get QGIS information about the current installation - `load_project` - Load a QGIS project from the specified path - `create_new_project` - Create a new project and save it - `get_project_info` - Get current project information - `add_vector_layer` - Add a vector layer to the project - `add_raster_layer` - Add a raster layer to the project - `get_layers` - Retrieve all layers in the current project - `remove_layer` - Remove a layer from the project by its ID - `zoom_to_layer` - Zoom to the extent of a specified layer - `get_layer_features` - Retrieve features from a vector layer with an optional limit - `execute_processing` - Execute a processing algorithm with the given parameters - `save_project` - Save the current project to the given path - `render_map` - Render the current map view to an image file - `execute_code` - Execute arbitrary PyQGIS code provided as a string ### Example Commands This is the example I used for the [demo](https://x.com/jjsantoso/status/1900293848271667395): ```plain You
