The GIS Data Conversion MCP is an MCP (Model Context Protocol) server that gives LLMs access to geographic data conversion tools.

This server uses various GIS libraries to allow LLMs to convert between different geographic data formats, coordinate systems, and spatial references.

• Reverse Geocoding - Convert coordinates to location information
• WKT/GeoJSON Conversion - Convert between Well-Known Text and GeoJSON formats
• CSV/GeoJSON Conversion - Transform tabular data with coordinates to GeoJSON and vice versa
• TopoJSON/GeoJSON Conversion - Convert between GeoJSON and TopoJSON (topology-preserving format)
• KML/GeoJSON Conversion - Transform KML files to GeoJSON format

To use this server with Claude Desktop, you need to configure it in the MCP settings:

For macOS: Edit the file at '~/Library/Application Support/Claude/claude_desktop_config.json'

{
  "mcpServers": {
    "gis-dataconversion-mcp": {
    "command": "npx",
    "args": [
      "-y",
      "a11y-mcp-server"
    ]
   }
  }
}

For Windows: Edit the file at %APPDATA%\Claude\settings\claude_mcp_settings.json

For Linux: Edit the file at ~/.config/Claude/settings/claude_mcp_settings.json Replace /path/to/axe-mcp-server/build/index.js with the actual path to your compiled server file.
