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
Run the meridian-mcp binary locally and add it to your Claude Desktop config. The binary connects to the hosted API using your key.
cargo install meridian-mcp
{
"mcpServers": {
"meridian-node": {
"command": "meridian-mcp",
"env": {
"MERIDIAN_API_KEY": "YOUR_API_KEY",
"MERIDIAN_BASE_URL": "https://meridianapi.nodeapi.ai"
}
}
}
}
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 will call the right endpoint.
For agents that support remote MCP over HTTP SSE, point directly at the hosted server. No local binary needed.

Any HTTP client works. POST your file with your API key, get your result.
