A3.6/5.0
Scored across 14 tools
Disambiguation3/5
Read, search, publish, and account tools are clearly distinct, but the write/upload surface has several overlapping paths: create_map, create_upload_link, the start/upload_part/finish chunked-upload trio, and replace_map_content all create or overwrite map content. The descriptions explain size limits and transport differences, but an agent still has to reason carefully about when to use each path.
Naming Consistency5/5
All tool names use lowercase snake_case and follow a predictable verb_noun pattern such as create_map, get_map, list_maps, publish_map, and search_maps. The upload-specific names are slightly longer but remain consistent with the same convention.
Tool Count4/5
The 14-tool set is within a reasonable range for map creation, upload, publishing, and search workflows. The count is slightly inflated by having multiple upload mechanisms, but each tool still corresponds to a real operation in the lifecycle.
Completeness4/5
The surface covers account info, map format, creation, large/chunked upload, replacement, listing, retrieval, search, publishing, and unpublishing. Minor gaps remain, notably no delete_map or abort-upload operation, but core workflows are well supported.

Available Tools
14 toolscreate_mapCreate a mapAInspect
Create a new private draft map from an import JSON of up to about 1 MB.
Inputs: map (required).
create_upload_linkCreate an upload linkBRead-onlyInspect
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.
Inputs: mode, mapId.
finish_map_uploadFinish a chunked map uploadADestructiveInspect
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.
Inputs: parts (required), uploadId (required).
get_accountGet accountARead-onlyInspect
The signed-in user's public handle, plan and how many maps they can still create.
Inputs: no named parameters.
get_import_formatGet the map import formatARead-onlyInspect
The JSON format for maps: layers with timed polygon keyframes, point markers and a style.
Inputs: no named parameters.
get_mapGet a mapARead-onlyInspect
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.
Inputs: mapId (required).
get_public_mapGet a published mapARead-onlyInspect
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.
Inputs: url, slug, username.
list_mapsList my mapsARead-onlyInspect
The user's maps, most recently changed first, with their ids and links.
Inputs: limit, search.
publish_mapPublish a mapAInspect
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.
Inputs: mapId (required).
replace_map_contentReplace a map's contentADestructiveIdempotentInspect
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.
Inputs: map (required), mapId (required).
search_mapsSearch published mapsARead-onlyInspect
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.
Inputs: year, limit, query.
start_map_uploadStart a chunked map uploadBInspect
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.
Inputs: mode, mapId.
unpublish_mapUnpublish a mapAInspect
Make one of the user's maps private again (its public link stops working).
Inputs: mapId (required).
upload_map_partUpload one part of a mapAIdempotentInspect
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.
Inputs: part (required), text (required), uploadId (required).
