Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "mapcast": {
      "command": "npx",
      "args": [
        "-y",
        "mapcast",
        "mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add mapcast -- npx -y mapcast mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "mapcast": {
      "command": "npx",
      "args": [
        "-y",
        "mapcast",
        "mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

Common questions

Is mapcast 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?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.1) reached the registry 6 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

mapcast

Animated map videos for explainers, documentaries and Shorts, from one line of JSON. Highlight any country, state or province on real satellite imagery or an old paper map: tracing borders, flags, glow, labels, capitals, data colours, a 3D globe dive and camera flights between countries. Free, open source, and built for AI agents to drive.

Full-quality version: docs/showcase.mp4

npx mapcast quick India -o india.mp4

That is the whole setup. The first run downloads Chromium and map data once (both cached); videos also need ffmpeg.

Ask your AI for it

mapcast is made to be driven by AI tools: you describe the map, the agent writes the scene, mapcast renders it.

"Make a YouTube Short that spins the globe and lands on Brazil with its flag."

"Old parchment map of Turkey, zooming in, with Istanbul marked."

"Colour these countries by unemployment: Spain 11.4, Greece 9.8, Germany 3.4."

Claude Code (skill and MCP server in one install):

/plugin marketplace add 21prnv/mapcast

/plugin install mapcast@mapcast

Claude Desktop, Cursor, Windsurf, Codex or any MCP client: add this to the client's MCP config.

"mcpServers": { "mapcast": { "command": "npx", "args": ["-y", "mapcast", "mcp"] } } }

The server offers render_map (saves the video or image and returns a preview of the final frame, so the agent can check its work) and preview_map (one frame, to check a scene before rendering). Every option is described in the tool schema.

Agents that read `SKILL.md` skills: npx skills add 21prnv/mapcast. The skill is in skills/mapcast, with 27 worked request-to-scene examples.

What it can do

Styles: colour tint that keeps the terrain visible, spotlight (rest of the world turns grey), outline, or the country's flag laid over its land.
Basemaps: NASA Blue Marble and Sentinel-2 satellite imagery, or an old parchment map with engraved coasts.
Cameras: slow push-in, zoom in from a wide view, dive from a spinning 3D globe, fly from country to country.
Places: every country by name or ISO code, plus 4,500 states and provinces ("California", "IN-MH"), with capitals or any city marked.
Data maps: colour countries by a number with a legend, with names and values on the map.
Formats: MP4, GIF, PNG, JPG in 16:9, 9:16, 1:1 or 4:5.
Disputed borders: drawn the way the highlighted country officially draws them, or a neutral view on request.

Scene format

"aspect": "16:9", "duration": 5, "camera": "push-in", "highlights": [ { "country": "India", "style": "solid", "color": "#c8102e", "label": "INDIA" } ] }

Field	Values	Default
`aspect`	`16:9`, `9:16`, `1:1`, `4:5` (or set `width`/`height`)	`16:9`
`duration`	seconds	`5` (`7` for `globe`, `1 + 3` per country for `fly`)
`fps`	frames per second	`30`
`camera`	`push-in`, `zoom-in`, `globe` (3D Earth dive), `fly` (country to country), `static`, or `{ "move", "fill", "from" }`	`push-in`
`basemap`	`satellite`, `bluemarble`, `sentinel`, `paper` (old parchment map)	`satellite`
`pov`	`auto` (the country's own official borders), `default`, or a code like `ind`, `chn`, `pak`	`auto`
`effects.grade`	`natural`, `muted`, `mono`	`natural`
`effects.vignette`	0 to 1	`0.45`
`effects.blur`	0 to 1: soft-focus edges, like a camera lens	`0`
`effects.grid`	`true` or `{ "step", "color", "opacity" }`: lat/long grid over the sea only	off
`effects.borders`	`true`: thin borders of neighbouring countries	on for `paper` and states
`labelAnim`	default label animation for every highlight	`rise`

Each highlight:

Field	Values	Default
`country`	name (`"India"`) or ISO code (`"IN"`, `"IND"`)	`country` or `region` required
`region`	a state or province: `"California"`, `"Bavaria"`, `"US-CA"`, `"IN-MH"`
`style`	`solid` (tinted fill), `highlight` (rest of the world goes grey), `outline`, `flag` (the country's flag over the terrain)	`solid`
`color`	any CSS colour or `red`, `yellow`, `blue`, ...	a distinct colour per country
`label`	text, or `false` for none	the country name
`border`	`{ "color", "width", "glow" }` or `false`	white, glowing
`labelAnim`	`rise`, `type` (typewriter), `spread` (letters close in), `slide`, `pop`	`rise`
`labelSize`	multiplier on the automatic label size, e.g. `0.7` or `1.3`	`1`
`labelFont`	`sans`, `serif`, or any font name	`sans` (`serif` on paper)
`capital`	`true` for the capital (a state's own capital for `region`), or a city name like `"Mumbai"`	off
`start`	seconds when this country starts animating	staggered automatically

Data maps

Colour countries by a number, with a legend:

"data": { "title": "GDP 2024 (trillion US$)", "prefix": "$", "unit": "T", "scheme": "heat", "values": { "India": 3.9, "China": 18.7, "Japan": 4.1 } } }

scheme is one of reds, blues, greens, heat, purples, diverging, or a list of colours. Set "labels" to "name", "value" (the number with prefix/unit) or "both" to label each country, and min/max to fix the colour range. A highlight's label can have a second line: "INDIA\n1.4 BILLION".

How it works

A scene is resolved against Natural Earth borders, the imagery tiles the camera path needs are fetched and cached, and a headless Chromium draws each frame on a canvas (WebGL for the globe). Frames are piped to ffmpeg. A 5 second 1080p clip takes about 15 seconds on a laptop.

Credits and licence

MIT. Map data, imagery and font licences are in NOTICE.md. Satellite imagery needs a credit line wherever you publish; mapcast prints the exact line after every render.
