Quantum GIS (QGIS) MCP

This project explores ways to interact with QGIS using the QGIS MCP Plugin and an MCP Server.

QGIS MCP Setup

1. Install QGIS MCP Plugin.

   • Plugins > Manage and install plugins

   • Source code at github.com/nkarasiak/qgis-mcp

2. Set configuration to start MCP server on start-up.

3. Configure the LLM (e.g. Claude Code) as directed.

4. Ask the LLM to ping QGIS.

Future

• Test suite.

• Consider running the entire application on an AWS EC2.

  • Easily see use cases with times that exceed maximum Lambda timeout.

  • Consider FastAPI for REST endpoints.
