Overview

What is GIS Data Conversion MCP?

GIS Data Conversion MCP is an MCP (Model Context Protocol) server that provides LLMs with tools for converting between common geographic data formats. It supports reverse geocoding, WKT/GeoJSON, CSV/GeoJSON, TopoJSON/GeoJSON, and KML/GeoJSON conversions.

How to use GIS Data Conversion MCP?

Install by configuring the server in your Claude Desktop MCP settings file (e.g. claude_desktop_config.json on macOS). The server is run via npx with the package a11y-mcp-server. Once configured, Claude can invoke the available conversion tools by name.

Key features of GIS Data Conversion MCP

  • Reverse geocoding to convert coordinates to location names.
  • Conversion between WKT and GeoJSON formats.
  • Conversion between CSV and GeoJSON formats.
  • Conversion between TopoJSON and GeoJSON formats.
  • Conversion between KML and GeoJSON formats.

Use cases of GIS Data Conversion MCP

  • Convert geographic coordinate data into readable location names.
  • Transform spatial data between common GIS formats for analysis or mapping.
  • Import tabular data with latitude/longitude fields as GeoJSON for web maps.
  • Export KML files from mapping applications to GeoJSON for further processing.
  • Simplify large GeoJSON datasets into more compact TopoJSON.

FAQ from GIS Data Conversion MCP

What dependencies does GIS Data Conversion MCP use?

The server depends on @modelcontextprotocol/sdk, wellknown, csv2geojson, topojson-client, topojson-server, @tmcw/togeojson, and xmldom.

How do I install GIS Data Conversion MCP?

Install by editing your Claude Desktop MCP settings file (location varies by OS) and adding the server with command npx and arguments -y a11y-mcp-server.

What format conversions are supported?

Supported conversions include WKT ↔ GeoJSON, CSV ↔ GeoJSON, GeoJSON ↔ TopoJSON, KML ↔ GeoJSON, and reverse geocoding (coordinates to location name).

What parameters does csv_to_geojson require?

It requires csv (CSV string), latfield (latitude column name), lonfield (longitude column name), and an optional delimiter (default comma).

What is the default quantization for TopoJSON conversion?

The default quantization parameter is 1e4; set it to 0 to disable simplification.
