landbenchmark-mcp

landbenchmark-mcp

An MCP server that lets AI agents run satellite land due-diligence through LandBenchmark. It exposes one tool, analyze_parcel, that returns a green / caution / walk-away verdict with cited signals (flooding, slope & buildability, soil, hazards, access) for any parcel.

Why

When someone asks their AI assistant "is this land any good to buy?", the agent can call LandBenchmark and answer with observed, cited satellite data instead of guessing.

Setup

• Get an API key at landbenchmark.com/account → API keys.
• Add the server to your MCP client config:

{
  "mcpServers": {
    "terrain": {
      "command": "npx",
      "args": ["-y", "landbenchmark-mcp"],
      "env": {
        "TERRAIN_API_KEY": "tk_live_...",
        "TERRAIN_BASE_URL": "https://www.landbenchmark.com"
      }
    }
  }
}

Both env vars are required. (TERRAIN_* is the internal engine name — LandBenchmark runs on the Terrain analysis engine.) TERRAIN_BASE_URL has no default on purpose: every request sends your API key to that host in an Authorization header, so the server refuses to start rather than guess where it goes. It also refuses to send a key over plain http:// to anything but localhost.

Works with any MCP-capable client — Claude Desktop, Claude Code, and agent frameworks.

Tool: analyze_parcel

Param	Type	Notes
lat, lon	number	Parcel centre (WGS84). Provide these or geometry.
geometry	GeoJSON	Polygon or Point (alternative to lat/lon).
label	string	Optional parcel name.
mode	"lite" | "full"	lite (default) ≈ 1 min; full = deep multi-year satellite report ≈ 3–4 min.

Returns a plain-text verdict summary with the flagged signals and a link to the full report.

Build

npm install
npm run build   # → dist/index.js
npm test        # verifies the API-key safety guard
