Meridian Node is a free GIS and raster processing API with 43 production endpoints. Built to be called by AI agents via MCP — and equally usable from any HTTP client, script, or workflow. Authenticate with an API key via the X-Mcp-Key header. No subscriptions, no dashboard, no setup maze.
Meridian Node is designed first and foremost as an MCP server — giving AI agents direct access to 43 GIS tools with no wrappers, no glue code, and no manual prompt engineering.
Install the Meridian Node skill from ClawHub. Your agent gains full knowledge of the API surface with a single command — no configuration needed.
clawhub install meridian
One command. No binary to install — connects directly to the hosted MCP server over SSE.
claude mcp add meridian-node \ --transport sse \ https://meridianapi.nodeapi.ai/sse \ --header "X-Mcp-Key: YOUR_API_KEY"
All 43 Meridian Node tools are immediately available in your Claude Code session. Ask it to reproject, buffer, clip, run raster math, package a GDB — it calls the right endpoint automatically.
Add the hosted MCP server to your config. No binary needed.

The Meridian Node tools appear automatically in Claude's tool list. Ask Claude to buffer a shapefile, clip to an AOI, or run a raster calculation — it handles the rest.
Any HTTP client works. POST your file with your API key, get your result.
