Schema Quality & AI Usability62
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 790 tokens (~395/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 2 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Unverified: 1 category
A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
preview_map ~341
Quickly render one frame of a scene and return it as an image, without making a video. Use it to check framing, colours and labels before render_map. Highlights countries on real satellite imagery (or an old paper map) with a tracing border, colour fill, glow and label, the look of documentary/explainer YouTube videos. Write a scene: { "highlights": [{ "country": "India" }] } is a complete one. Add only what the request asks for; defaults look good. Map requests to fields: a colour -> highlights[].color; "show the flag" -> style "flag"; "rest of the world grey/dark" -> style "highlight"; "just the border" -> style "outline"; "old map / history / parchment" -> basemap "paper"; "from space / the globe / spinning Earth" -> camera "globe"; "zoom in from far away" -> camera "zoom-in"; "travel/tour/go from X to Y" -> camera "fly" with highlights in visiting order; a state or province -> highlights[].region; "Shorts/Reels/TikTok/vertical" -> aspect "9:16"; "mark the capital" -> capital true; "compare countries by <number>" -> data.values with a title. Borders follow the highlighted country's official view of disputed areas (pov "auto").
| Name | Type | Req | Description |
|---|---|---|---|
| at | number | – | Second to show. Default: the final frame (everything visible). |
| scene | object | yes | An animated map: one or more highlighted countries, a basemap, a camera move and effects. Needs "highlights" or "data". |
No output schema declared.
No examples provided.
render_map ~449
Render an animated map video (.mp4, .gif) or image (.png, .jpg) and save it to disk. Returns the file path, the imagery credit line (must be shown wherever the video is published) and a small preview of the final frame. Highlights countries on real satellite imagery (or an old paper map) with a tracing border, colour fill, glow and label, the look of documentary/explainer YouTube videos. Write a scene: { "highlights": [{ "country": "India" }] } is a complete one. Add only what the request asks for; defaults look good. Map requests to fields: a colour -> highlights[].color; "show the flag" -> style "flag"; "rest of the world grey/dark" -> style "highlight"; "just the border" -> style "outline"; "old map / history / parchment" -> basemap "paper"; "from space / the globe / spinning Earth" -> camera "globe"; "zoom in from far away" -> camera "zoom-in"; "travel/tour/go from X to Y" -> camera "fly" with highlights in visiting order; a state or province -> highlights[].region; "Shorts/Reels/TikTok/vertical" -> aspect "9:16"; "mark the capital" -> capital true; "compare countries by <number>" -> data.values with a title. Borders follow the highlighted country's official view of disputed areas (pov "auto"). A 5 second 1080p video takes roughly 10-30 seconds. Use preview_map first when unsure how a scene will look.
| Name | Type | Req | Description |
|---|---|---|---|
| at | number | – | Stills only: the second to capture. Default: the final frame. |
| output | string | – | Where to save it; the extension picks the format (.png, .jpg, .jpeg, .mp4, .gif). Relative paths resolve against the server's working directory. Default: mapcast-output/map-<time>.mp4. |
| scene | object | yes | An animated map: one or more highlighted countries, a basemap, a camera move and effects. Needs "highlights" or "data". |
