GeoCalculator helps you convert lat long or coordinates easily and accurately for GIS and spatial analysis, saving time
Performs geospatial calculations including coordinate system conversions between Chinese mapping systems (BD09, GCJ02) and international standards (WGS84, Web Mercator), plus distance and area calculations.
GeoCalculator is a community-built MCP server published by nodegis that provides AI assistants with tools and capabilities via the Model Context Protocol. GeoCalculator helps you convert lat long or coordinates easily and accurately for GIS and spatial analysis, saving time It is categorized under analytics data. This server exposes 3 tools that AI clients can invoke during conversations and coding sessions.
You can install GeoCalculator in your AI client of choice. Use the install panel on this page to get one-click setup for Cursor, Claude Desktop, VS Code, and other MCP-compatible clients. This server runs locally on your machine via the stdio transport.

💡 Pro Tips
Architecture
Model Context Protocol standardizes how AI hosts (Claude, Cursor) communicate with external tools and data sources through server implementations.
Protocols
Compatibility
✓ Use when
Use when you need Claude to access external data, execute actions, or integrate with tools. Best for extending AI capabilities beyond conversation.
✗ Avoid when
Avoid when native integrations exist (use official APIs directly), for real-time critical systems, or when security/compliance requires zero external dependencies.
