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 →
sea_route Shortest sea route ~268
Compute the shortest maritime route between two points (UN/LOCODE port codes like "CNSHA", or [lon, lat] coordinates). Returns distance, optional duration, the canals/straits traversed, and the route GeoJSON. Supports passage restrictions (e.g. avoid Suez), arctic gating, and vessel-draft-aware canal avoidance.
| Name | Type | Req | Description |
|---|---|---|---|
| allowArctic | boolean | – | Allow the ice-blocked Northwest/Northeast Passages (blocked by default). |
| destination | – | yes | – |
| includeGeometry | boolean | – | Include the route LineString GeoJSON in the result. |
| maxSnapDistanceKm | number | – | Reject inputs farther than this (km) from the maritime network. |
| origin | – | yes | A UN/LOCODE port code string, or a [longitude, latitude] coordinate pair. |
| restrictions | array | – | Named passages the route must avoid. e.g. ["suez","babelmandeb"] forces Cape of Good Hope routing during a Red Sea disruption. |
| speedKnots | number | – | Vessel speed in knots; when given, an estimated duration in hours is returned. |
| units | string | – | Unit for the returned distance. |
| vesselDraftMeters | number | – | Vessel draft in metres; canals too shallow for it are auto-avoided. |
No output schema declared.
No examples provided.
sea_route_alternatives Alternative sea routes ~234
Return up to k distinct alternative maritime routes between two points, each blocking a different combination of major canals/straits (e.g. baseline vs. no-Suez vs. no-Panama), sorted by distance. Useful for comparing "via Suez" against "via Cape of Good Hope".
| Name | Type | Req | Description |
|---|---|---|---|
| allowArctic | boolean | – | Allow the ice-blocked Northwest/Northeast Passages (blocked by default). |
| destination | – | yes | – |
| includeGeometry | boolean | – | Include each route LineString GeoJSON in the result (off by default; verbose). |
| k | integer | – | Maximum number of distinct alternative routes to return. |
| origin | – | yes | A UN/LOCODE port code string, or a [longitude, latitude] coordinate pair. |
| restrictions | array | – | Named passages the route must avoid. e.g. ["suez","babelmandeb"] forces Cape of Good Hope routing during a Red Sea disruption. |
| units | string | – | Unit for the returned distance. |
| vesselDraftMeters | number | – | Vessel draft in metres; canals too shallow for it are auto-avoided. |
