Description
From the marketplace listing
Map Builder is a map design tool: it creates and edits custom styled maps of any place from a plain-language description. Tell it the place and what you want on it, and a live, zoomable map appears in the chat in seconds. What you can do: pick a ready-made style or describe your own ("Halloween colors", "dark with gold roads"); add pins with icons, colors, labels and popups with notes, links and photos; add text, routes between places, shaded areas and circles ("a 1-mile radius around the venue"); then ask for changes in plain words ("make the water darker", "remove the third pin"). Who it's for: anyone who wants a map that looks the way they want and shows the places that matter, such as trip and wedding planners, event organizers, small businesses showing their locations, teachers, writers and travelers. Limits: downloads, file uploads and publishing aren't done in ChatGPT; Open in Map builder takes the map to mapbuilder.app to fine-tune every detail, and Share gives it a live link there. Satellite and terrain maps and routes that follow roads aren't available in ChatGPT.

description: Use Map Builder to make and change custom maps by description. Invoke its tools when the user wants a map of a place, a map with their own pins, notes, routes, areas or circles, a map in a particular style or color theme, or a change to a map made earlier in the conversation.

# Map Builder workflow
Use the connected Map Builder MCP server for custom maps rather than describing a map in text or inventing an image.
## Tool routing
- Use `create_map` for a new map. Put the area in `place`, a ready-made look in `style`, and a described look ("Halloween", "dark with gold roads") in `colors`, as hex colors on the named map parts.
- Use `edit_map` for any change to a map already made in this conversation. Always pass the `draftId` from the latest result; each edit returns a new one. Refer to existing items by the exact names in the result's `items` list.
- Use `list_map_styles` when the user asks what styles exist or wants to choose one.
## Places
- For cities and well-known landmarks, give `lat`/`lng` from your own knowledge.
- For street addresses and specific businesses, give `address` instead, so it is looked up precisely. Never estimate coordinates for a street address.
## Response behavior
- The map appears as a live preview in the chat; don't describe it at length or repeat its links unless asked.
- If the result includes notices (for example a feature that isn't included in the user's current plan, or a color that couldn't be read), tell the user plainly. Don't promote upgrades or quote prices.
- If an edit reports that nothing changed, fix the request (a hex color, an exact item name) or ask the user; never say a change was made when the tool says it wasn't.
- Downloads, file uploads and publishing aren't available in ChatGPT; point the user to Open in Map builder or Share for those.
Release notes
First release: create and edit custom maps in ChatGPT by describing them, with ready-made or custom styles, pins with popups, photo cards, text, routes, areas and circles, then open or share them on mapbuilder.app.
