On 2026-10-31 the server answered initialize and tools/list without a sign-in. First answer in 1763 ms.

• Its tools do every use case we checked: find when a satellite passes over your city; check upcoming launches and close approaches.
• Checked on 4 of the 7 days it takes to judge reliability.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

• Every tool passes all six checks.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• satellite_now

  Where one satellite is right now: the point on the ground beneath it, its altitude and speed, what it is over (a country or a sea), whether it is in sunlight or in the Earth's shadow, the orbit it is on, and what it is: its kind, its…

• passes

  When satellites pass over a place in the next ten days, in the place's local time: for one satellite, every pass with its rise, highest point and set, and whether it can be seen; with no satellite named, the passes a person can see with…

• launches

  Rocket launches coming up in the next sixty days and launched in the last thirty, from Launch Library 2: for each, the rocket and the mission, what it carries and where it is bound, the launch site, its time as exactly as the provider…

• close_approaches

  The close approaches between objects in orbit that Space-Track reports publicly: two objects predicted to pass within about a kilometre of each other, with the time of closest approach in UTC, the miss distance, the chance of collision…

• reentries

  Which objects in orbit are expected to fall back to Earth within the next week, each with the window Space-Track predicts (a start and an end in UTC, never a place), and which came down in the last ninety days, each with the day the…

• crew

  Who is aboard each space station right now (the International Space Station and Tiangong), as Launch Library lists their expeditions: each person's name, role, agency, the flight that brought them and the day it docked, with the crew…

• census

  How many satellites and other objects are in orbit around Earth right now, counted by kind (satellites, rocket bodies, debris, unidentified) and by orbit (low, medium, inclined geosynchronous, geostationary, highly elliptical). Call it…
