Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 434 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name moving-polygons.

  • Pass
    Lists tools

    tools/list returned 14 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 434 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 434 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Fail
    Parameters documented

    18 of 23 parameters have a description (78%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Pass
    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass
    Recently updated

Capabilities

Tools 14

create_map

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

Discovered
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.

Discovered
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.

Discovered
get_account

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

Discovered
get_import_format

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

Discovered
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.

Discovered
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.

Discovered
list_maps

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

Discovered
publish_map

Make one of the user's maps public at its /map/<handle>/<slug> 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.

Discovered
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.

Discovered
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.

Discovered
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.

Discovered
unpublish_map

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

Discovered
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.
