geo-mcp-servers is a curated registry of Model Context Protocol (MCP) servers for geospatial, GIS, mapping, and earth observation work. It’s maintained on GitHub at sparkgeo/geo-mcp-servers and currently tracks 82 (and counting) servers across 10 categories, from geocoding and routing to satellite imagery and desktop GIS.

Every entry comes from a single source of truth, servers.yaml. The README is generated from that file with a Python script rather than edited by hand, so the list stays accurate as servers are added, updated, or retired.

The Problem it Solves

MCP gives AI assistants a standard way to call external tools and data sources instead of relying on custom, one-off integrations. Since Anthropic introduced the protocol in late 2024, the geospatial community has built dozens of servers wrapping geocoders, routing engines, STAC catalogs, weather APIs, and desktop GIS software.

The problem is that these servers are scattered across individual repos with no shared index. A developer wanting to connect an AI assistant to a geocoder, a satellite imagery catalog, or a routing engine has no easy way to know what already exists, who built it, or whether it’s still maintained. geo-mcp-servers exists to close that gap: one place to check before building a new server from scratch, and one place to list a server after building it.

How to Contribute

The registry grows through community contributions, and adding a server takes one of two paths:

• Open a GitHub issue using the provided template with the server’s name, repository link, and a short description.
• Edit servers.yaml directly and regenerate the documentation using the included Python script, then submit a pull request.

A bundled Claude Code skill also supports searching and registering servers conversationally, so you can query the registry or add a new entry without leaving your AI assistant.
