What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

• get_import_format

  The JSON format for maps: layers with timed polygon keyframes, point markers and a style.

• get_account

  The signed-in user's public handle, plan and how many maps they can still create.

• list_maps

  The user's maps, most recently changed first, with their ids and links.

• get_map

  A summary of one of the user's maps (layers, keyframe dates, markers) and a 15-minute download link for its full import JSON, which can be several MB.

• create_map

  Create a new private draft map from an import JSON of up to about 1 MB.

• create_upload_link

  A one-off link (valid 15 minutes) for uploading a map JSON file of up to 40 MB with curl. It creates a new draft map, or with mode replace overwrites an existing map's content. The curl output reports the result.

• start_map_upload

  Opens an upload (valid 2 hours) for a map JSON text that is sent in numbered parts through tool calls rather than over the network. It creates a new draft map, or with mode replace overwrites an existing map's content.

• upload_map_part

  Stores one numbered piece of a chunked map upload. The pieces are joined in part order with nothing in between; sending a part number again replaces that part. Returns the piece's length and SHA-256.

• finish_map_upload

  Joins parts 1 to the given count of a chunked upload, validates the map and creates the draft map (or replaces the map's content, keeping a backup). Reports missing parts or where the JSON breaks.

• replace_map_content

  Overwrite an existing map's layers, markers, name, description and casualty bar (and style, if given) with an import JSON of up to about 1 MB. The link and publish state stay; the old content is backed up.

• publish_map

  Make one of the user's maps public at its /map/ / link, where anyone can view it. The user must first choose a username at https://www.movingpolygons.com/settings; until then this fails and says so.

• unpublish_map

  Make one of the user's maps private again (its public link stops working).

• search_maps

  Find published animated maps on Moving Polygons (history, wars, empires, borders, epidemics, sea ice…) by words in their title or description and/or a year they cover. Returns links to the interactive map, its text version and its article.

• get_public_map

  One published map as Markdown: description and sources, the timeline of keyframes (date and caption), layers, events, and the iframe code to embed the interactive map. Pass its URL, or the handle and slug.
