MCP 服务器

GIS Data Conversion MCP

An MCP server that gives LLMs access to geographic data conversion tools, enabling transformations between different formats like WKT, GeoJSON, CSV, TopoJSON, and KML, as well as performing reverse geocoding.

Tools

wkt_to_geojson

Convert Well-Known Text (WKT) to GeoJSON format

geojson_to_wkt

Convert GeoJSON to Well-Known Text (WKT) format

csv_to_geojson

Convert CSV with geographic data to GeoJSON

geojson_to_csv

Convert GeoJSON to CSV format

geojson_to_topojson

Convert GeoJSON to TopoJSON format (more compact with shared boundaries)

topojson_to_geojson

Convert TopoJSON to GeoJSON format

kml_to_geojson

Convert KML to GeoJSON format

geojson_to_kml

Convert GeoJSON to KML format

coordinates_to_location

Convert latitude/longitude coordinates to location name using reverse geocoding

Copy of Untitled Design

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.

Features

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

Installation

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.
