      ],
      "env": {
        "ULTIMAPS_API_KEY": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add --transport http ultimaps https://api.ultimaps.com/mcp --header 'Authorization: your-value'

Or run it on your computer

claude mcp add ultimaps --env ULTIMAPS_API_KEY=your-value -- npx -y @ultimaps/mcp

Your choice stays on this device in a cookie; no account needed.

Values you fill in

ULTIMAPS_API_KEY secret env
Optional API key. Without one you get 30 maps per hour with attribution. A key raises the limits, and a Pro key adds SVG, larger PNGs and no attribution.
Authorization secret HTTP header
Optional. Bearer for plan quotas. Without a key you get 30 maps per hour per conversation, with attribution.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Ultimaps safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: ULTIMAPS_API_KEY, Authorization

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.0) reached the registry 17 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

README from the maker

Open the README

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.

@ultimaps/mcp

An MCP server for Ultimaps. Ask Claude, Codex or any MCP client for a map and get the image back in the conversation. It covers choropleths from pasted numbers, category maps and pinned locations, for countries, states, provinces, counties, continents and the world.

"Map US states by population." · "Color the EU members by currency." · "Show France's regions with these unemployment rates: …" · "Pin our five offices on a map of Europe."

No account needed. Without an API key the server uses the keyless tier. Set ULTIMAPS_API_KEY for plan quotas and larger or unbranded output.

Can't run a local command? In ChatGPT (developer mode), claude.ai or any client that connects to remote MCP servers, add the hosted server instead: https://api.ultimaps.com/mcp. In ChatGPT, turn it on in each conversation where you want maps. It has the same three tools and nothing to install. See Hosted server. This package is the local version: requests come from your own IP address with your own key, and every image is saved to a file on your computer.

Tools

Tool	What it does
`render_map`	Renders a map as an image (PNG, or SVG with a Pro key), shown inline when it is small enough. Choropleth (numbers), categories (labels) or explicit colors, plus pins, title, a legend with its own heading, theme, region labels (names, values or both) and extra layers. Region names are matched fuzzily, and every correction or miss is reported with suggestions. `dryRun: true` previews matching and the color plan without rendering.
`list_maps`	The map catalog: `{id, title, regionType, layers, regionCount, labels}`, searchable with `query`.
`get_map_regions`	One map's region keys and titles, 200 per page, searchable by key, title or alias.

All three are read-only. Agents rarely need the discovery tools: render_map accepts region names, codes and aliases directly.

Install

Requires Node.js 20 or newer.

Claude Code

claude mcp add ultimaps -- npx -y @ultimaps/mcp

with a key:

claude mcp add ultimaps --env ULTIMAPS_API_KEY=um_live_… -- npx -y @ultimaps/mcp

Codex

codex mcp add ultimaps -- npx -y @ultimaps/mcp

with a key:

codex mcp add ultimaps --env ULTIMAPS_API_KEY=um_live_… -- npx -y @ultimaps/mcp

Codex writes TOML, not the JSON below. The equivalent entry in ~/.codex/config.toml (or .codex/config.toml in a trusted project):

[mcp_servers.ultimaps]

command = "npx" args = ["-y", "@ultimaps/mcp"]

Claude Desktop

Download ultimaps- .mcpb from the latest release and open it: Claude Desktop installs it in one click and asks for the optional API key. Or add this to claude_desktop_config.json:

"mcpServers": { "ultimaps": { "command": "npx", "args": ["-y", "@ultimaps/mcp"], "env": { "ULTIMAPS_API_KEY": "" } } } }

Cursor

~/.cursor/mcp.json (or .cursor/mcp.json in a project):

"mcpServers": { "ultimaps": { "command": "npx", "args": ["-y", "@ultimaps/mcp"] } } }

VS Code

.vscode/mcp.json:

"servers": { "ultimaps": { "type": "stdio", "command": "npx", "args": ["-y", "@ultimaps/mcp"] } } }

Hosted server

You don't need this package to use the hosted server. Add the URL to your client:

claude mcp add --transport http ultimaps https://api.ultimaps.com/mcp

with a key:

claude mcp add --transport http ultimaps https://api.ultimaps.com/mcp \ --header "Authorization: Bearer um_live_…"

Clients with a config file take the URL alone, for example ~/.cursor/mcp.json:

"mcpServers": { "ultimaps": { "url": "https://api.ultimaps.com/mcp" } } }

The hosted server sends a key as an Authorization header, not as ULTIMAPS_API_KEY. In ChatGPT and claude.ai you can't set headers, so renders there use the anonymous tier: PNG up to 1600 px with attribution, up to 30 per hour per conversation. Every render also comes back as an image link that expires after 30 days. Images too large for the conversation, and all SVGs, come back only as the link. ChatGPT doesn't show images returned by tools, so the link is how you see the map there.

Configuration

Variable	Default	Purpose
`ULTIMAPS_API_KEY`	none (keyless)	API key from Studio → Workspace → API. An invalid key is an error and never falls back to keyless.
`ULTIMAPS_API_URL`	`https://api.ultimaps.com`	Point at a local API during development (`http://localhost:3001`). Plain http is only accepted for localhost.

Limits

	Keyless	Free key	Pro key
Renders	30/hour, 5/minute	500/month, 50/day, 10/minute	5,000/month, 1,000/day, 30/minute
Output	PNG up to 1600 px, attribution	PNG up to 1600 px at scale 2 (a 3200 px raster), attribution	PNG up to 4000 px at scale 4, SVG, no attribution

All keys in a workspace share the monthly quota. The daily and per-minute caps are per key, so a free key stops at 50 renders a day long before the month runs out.

Dry runs skip the monthly quota but still count against rate limits. When five or fewer keyless renders remain in the hour, the result says so.

What a render returns

The image, inline, when it is small enough (781 KB for PNG, 98 KB for SVG). The default 1200 px width usually fits. Every render is also written to /ultimaps-mcp/ and the path is in the result, so in a terminal client the file is the thing you can actually open. Nothing is re-rendered or resampled on your behalf.
A text report: auto-corrected and unmatched region keys with suggestions, the resolved choropleth plan, warnings (such as layer_unavailable or labels_overlap), a link to open the map in Ultimaps Studio for editing, and the render id for support.
An embeddable image URL for keyless PNG renders whose whole spec fits a ~2,000-character URL, so small datasets only. The URL carries the spec, not the image, and renders keyless, so it is not offered when a key is set.
`structuredContent` with the same report as data, described by the tool's outputSchema.

Privacy Policy

This server runs on your machine, has no telemetry of its own and talks only to the Ultimaps API (https://api.ultimaps.com, or the ULTIMAPS_API_URL you set). The full Ultimaps privacy policy is at ultimaps.com/privacy-policy.

What is sent to Ultimaps. Tool calls are ordinary HTTPS requests to the Ultimaps API, so they arrive from your IP address with an ultimaps-mcp/ user agent. render_map sends the whole map request: region keys and values, pins, title and styling. If you set ULTIMAPS_API_KEY, it is sent with render requests only.

What Ultimaps keeps. Each render request is logged: the request content, the map and outcome, timing, your IP address and user agent, and for keyed requests which key and workspace made it. This lets support look up a render id, lets the "Open in Studio" link rebuild your map, and counts usage. The request content is kept for 30 days and the IP address and user agent for 90 days. What remains is a usage record, tied to your workspace when a key was used. Ultimaps uses a third-party error-monitoring service that may receive details of a failed request. Ultimaps does not sell this data or use it for advertising.

What stays on your machine. Every rendered image is written to /ultimaps-mcp/ and this server never deletes it. What your MCP client keeps, including tool results in your conversation, is governed by its own privacy policy.

Shareable links. The embeddable image URL offered for small keyless renders contains the full map request. Anyone with the link can read it.

The hosted server. The server at https://api.ultimaps.com/mcp runs on Ultimaps' servers, not yours, so the section above about your machine doesn't apply to it. The full privacy policy covers it.

Questions or deletion requests: support@ultimaps.com, quoting the render id.

Development

npm install

npm run typecheck npm test # unit + in-process protocol tests npm run build # → dist/

End-to-end over stdio against a real API (spends render units from your tier):

npm run build

node scripts/smoke.mjs

src/generated/render-request.schema.json is generated from the Ultimaps API contract; do not edit it by hand. Tool and property descriptions live in src/descriptions.ts. Arguments are never validated locally: the API is additive-only, and its 400 responses carry suggestions.

Issues and pull requests are welcome. Releases are cut by the Ultimaps team, and accepted changes ship with the next release.

The package publishes a bin and nothing else. import '@ultimaps/mcp' is not supported and fails by name, because dist/index.js starts a stdio server when it loads.
