SkyGlance — What's Flying Above You tools (24)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

    What is about to pass overhead, within the next 90 seconds.

  • emergencies

    Aircraft squawking an emergency code, worldwide.

  • feed_health

    Per-source health: latency, failures, and whether a circuit breaker is open.

  • find_by_type

    Every airborne aircraft of one ICAO type code, worldwide or nearby.

Add to Cursor

What the publisher says

From the SkyGlance — What's Flying Above You repository's README, as published. We do not edit it. Read it on GitHub

<!-- mcp-name: io.github.darshjoshi/skyglance --> SkyGlance

Ask Claude what's flying above you. Live positions, real aircraft identities, routes, photographs — and a memory of everything that's passed over.

Quick Start

claude mcp add skyglance -- uvx --from skyglance skyglance

Then ask Claude: "What's flying over me right now?"

Needs uv (curl -LsSf https://astral.sh/uv/install.sh | sh). No API keys — every data source here is free.

Set your location so you can stop repeating it, and so SkyGlance can build a sighting history:

claude mcp add skyglance \
  -e SKYGLANCE_HOME_LAT=40.71 -e SKYGLANCE_HOME_LON=-74.01 \
  -- uvx --from skyglance skyglance

Install as a Claude Code plugin

Ships the server together with the sky skill, which teaches Claude how to read elevation angles and how to talk about aircraft to someone who has never spotted one.

/plugin marketplace add darshjoshi/skyglance-mcp
/plugin install skyglance@skyglance

What you can ask

"What's flying over me right now?"         → ranked by what you'd actually notice
"What's about to pass overhead?"           → but only 90 seconds ahead, honestly
"What is that plane?"                      → type, operator, route, photograph
"Where is flight UAL123?"                  → anywhere in the world
"Any A380s airborne?"                      → 44 of them, right now
"Any military aircraft near me?"           → and any emergencies, worldwide
"Have I ever seen this plane before?"      → your own history says
"What's the closest one ever?"             → your personal records
"Can I even see anything tonight?"         → cloud, visibility, daylight

Why it's shaped this way

"Over you" is an angle, not a distance. A radius filter returns an airliner at 38,000 ft that is 19 km away — sitting 32° above the horizon, a speck near the treeline — and gives it the same weight as a helicopter at 800 ft, at 0.7°, invisible behind buildings. SkyGlance computes the elevation angle, the compass bearing to look, and the slant range, so an answer tells you where to point your face.

It won't predict further than it can. Straight-line extrapolation from track and ground speed is accurate to about 0.11 km at 30 seconds. At four minutes the median miss is 6 km and 77% of aircraft are more than 2 km off, because aircraft on approach turn constantly. So countdowns stop at 90 seconds and anything beyond is reported as "inbound" with no number attached.

It knows when it can't see. Free ADS-B coverage comes from volunteers with receivers on their roofs. Dense Europe, US and East Asia get 90–95% of what a commercial feed shows. Oceans, Africa and central Asia get near zero. When results are thin, SkyGlance says so rather than implying an empty sky.

Your coordinates are rounded before they leave. Feed queries are coarsened to two decimal places (~1.1 km) so no volunteer feed operator gets a rooftop-accurate log of where you are and when you're awake. Bearing and elevation are still computed locally from your exact position, so what you're told to look at stays precise. There's a test that fails if an uncoarsened coordinate ever reaches a feed.
