About GeoLens

Apache-2.0 read-only Model Context Protocol server for GeoLens. Point a coding agent (Claude Code, Cursor, Codex, …) at a GeoLens instance so it can discover datasets, inspect schemas, read features and maps, and run read-only SQL from inside a dev session. It has no write, ingest or admin tools, and every call is scoped to the caller's access.

How do I install the GeoLens MCP server?

Is GeoLens free?

The server is open source under the Apache-2.0 license, so running it is free. It needs credentials (GEOLENS_API_KEY and GEOLENS_TOKEN) for the service it connects to, which may require a paid account.
