atlasfetch-mcp
No signup needed to try it: without a key it falls back to a shared public demo key, capped at 1,000 lookups a month across everyone using it. Get your own limits with a free sign-up at atlasfetch.xyz.
An MCP server for AtlasFetch — reverse geocoding to administrative boundaries, and geofencing, as tools your AI assistant can call directly.
Ask "which municipality is -33.9249, 18.4241 in?" and get Cape Town, Western Cape, South Africa with ISO 3166 codes — from a real point-in-polygon lookup, not the model's memory.
country: United Kingdom (GB) · region: England (GB-ENG) · municipal: City of Westminster (GB-WSM)
What it does
| Tool | What it does |
|---|---|
lookup_location | A coordinate becomes the country, region and municipality containing it, with ISO 3166-1 / 3166-2 codes, plus matches from your own boundary sets. Optionally returns the point as an H3 cell or Google Plus Code. |
list_boundary_sets | Lists your boundary sets, their counts, and which API keys may query them. |
create_boundary_set | Creates an empty set for your own polygons. |
add_boundary | Adds one GeoJSON polygon, with properties returned on every match. |
Good for: reverse geocoding to administrative areas, geofencing against your own delivery zones or service areas, jurisdiction and region checks, tagging location data with region codes.
Not for: street addresses or postcodes (this is not forward geocoding — results stop at the municipality), routing, distances, map tiles, or downloading boundary geometry.
Install
Claude Code
claude mcp add atlasfetch -- npx -y atlasfetch-mcp
Claude Desktop, Cursor, VS Code and other clients
Add to your MCP config (claude_desktop_config.json, .cursor/mcp.json, or your client's equivalent):
{
"mcpServers": {
"atlasfetch": {
"command": "npx",
"args": ["-y", "atlasfetch-mcp"],
"env": {
"ATLASFETCH_API_KEY": "your-key-here"
}
}
}
}
Requires Node 20 or newer.
Getting a key
The demo key is shared by every anonymous user on the internet — one pooled quota and rate limit. Fine for a first look, wrong for anything real.
Create your own at atlasfetch.xyz/dashboard and set ATLASFETCH_API_KEY. The free Personal plan needs no card.
| Variable | Default | Purpose |
|---|---|---|
ATLASFETCH_API_KEY | (demo key) | Your API key. |
ATLASFETCH_API_URL | https://api.atlasfetch.xyz | Override only for local or staging APIs. |
Two things that surprise people
municipal is the finest unit available, not a consistent kind of thing. Los Angeles returns a city; rural Kansas returns a county; some places return a district. Where a country's fine tier is patchy, a coarser complete tier answers instead, because a county beats null for most uses. Don't assume the value names a city.
A new boundary set cannot be made queryable from here. Sets are created switched off and granted to no key, and granting is addressed by API key id — which only a signed-in browser session can list. So this server can create a set and fill it, but the last step happens in the dashboard. create_boundary_set says so in its response rather than leaving you with a set that silently matches nothing.
Billing
One call is one lookup, however many layers, sets or grid codes it touches. Metering happens before matching, so a lookup that matches nothing still counts. Requests rejected as invalid or rate-limited are not billed.
Development
npm install
npm run build
node scripts/smoke.mjs # drives the built server with a real MCP client, against the live API
