Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

Tools (9)
⚪sky_seeing(lat, lon, tz_offset, when)
Is tonight actually usable for stargazing or astrophotography? Combines real dark hours and true moon illumination (computed from first principles) with live hourly cloud cover, weighting low cloud above high cloud. Returns a 0-100 usability score per night hour, the best consecutive usable run, and a plain verdict. lat/lon required; tz_offset and when optional.

}
},
"required": [
"lat",
"lon"
]
}🔴watch(action, id, min_magnitude, place, since_hours, ...)
Stateful quake subscriptions. Unlike a local tool, the filter and its cursor are stored on the server, so poll returns ONLY events newer than your last poll - no re-scanning, no client-side dedupe. Actions: create (min_magnitude, place), poll (id), list, delete (id).

"create",

},
"id": {
"type": "string",
"description": "Subscription id (for poll/delete)."
},
"min_magnitude": {
"type": "number",
"description": "Minimum magnitude for create. Default 0."
},
"place": {
"type": "string",
"description": "Substring place filter for create, e.g. 'Japan'."
},
"since_hours": {
"type": "number",
"description": "On create, seed the cursor this many hours back so the very first poll can return existing events. Default 0 (only new events)."
},
"owner": {
"type": "string",
"description": "Optional namespace to group subscriptions. Default 'public'."
}
},
"required": [
"action"

}⚪earthquakes(window, min_magnitude, place, limit)
Recent earthquakes from USGS. Filter by window (hour/day/week/month), minimum magnitude, and place text. Returns magnitude, place, depth, time.

"type": "number",
"description": "Minimum magnitude, e.g. 4.5. Default 0."
