## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 83/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 68/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1800 tokens (~225/item across 8 items; 8 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 17/100
  - Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 8 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## MCP tools (8)

### `find_satellites` (~188 tokens)

Find satellites

Finds satellites and other tracked objects by name, alias or catalogue number, in the catalogue of everything in orbit. Call it when a person names a satellite in words (Hubble, Starlink, Tiangong, a GPS satellite) to learn its catalogue number and alias. Each match says what the object is (a space station, a telescope, a rocket body, debris), which orbit it flies, whether it can be seen with the naked eye, and its page where it has one. It cannot tell where a satellite is now or when it passes over a place.

Input parameters:

- `language` (string): The language of the answer and of the page it links: en (the default) or es
- `query` (string, required): Part of the name, the alias or the catalogue number: iss, hubble, starlink, 25544. Case and accents do not matter.

### `satellite_now` (~187 tokens)

Where a satellite is 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 launch day and mass where the site has written them, and for a space station who is aboard, for a navigation satellite whether it is in service. Takes the satellite's alias (iss, hubble, tiangong) or catalogue number. It cannot predict when the satellite passes over a place and cannot answer for a constellation as a whole.

Input parameters:

- `language` (string): The language of the answer and of the page it links: en (the default) or es
- `satellite` (string, required): The satellite's alias (iss, hubble, tiangong) or catalogue number (25544).

### `passes` (~462 tokens)

Passes over a place

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 the naked eye (the ISS, Tiangong, Hubble and the other bright ones), soonest first. Call it when someone asks when they can see the ISS or any satellite from a city, or what passes over them tonight. Name the place (a city: Madrid, Brisbane, Buenos Aires, in English or Spanish) and the answer uses that place's time zone; or give latitude and longitude, and the answer is in UTC unless time_zone names a zone. A name several cities share is computed for the largest, and the answer names the others so you can ask again for one of them. Passes are predictions from the latest orbit data; a visible pass is one in a dark sky with the satellite in sunlight, at least ten degrees up and bright enough; it says nothing about clouds. It cannot answer for a geostationary satellite, which never rises or sets, and the place name or coordinates sent are computed with and never stored or logged.

Input parameters:

- `language` (string): The language of the answer and of the page it links: en (the default) or es
- `latitude` (number): Degrees north, when no place is named; with longitude.
- `longitude` (number): Degrees east, when no place is named; with latitude.
- `place` (string): The place's name, a city in English or Spanish (Madrid, Brisbane, Ciudad de México), or one of the alternatives a previous answer named (Portland, Maine, United States). Leave it out to give latitude…
- `satellite` (string): One satellite's alias (iss, hubble, tiangong) or catalogue number, for its passes alone; leave it out for every satellite visible to the naked eye.
- `time_zone` (string): An IANA time zone (Europe/Madrid, America/New_York) for the times of an answer by latitude and longitude; UTC when left out. A named place uses its own zone and ignores this.

### `launches` (~162 tokens)

Rocket 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 states it (a minute, a day, a month) in UTC, and its status (go, tentative, success, failure). Call it when asked what launches next, what launched recently, when a named launch is, or what is launching this week. Times move often; a tentative launch may slip. It cannot say where a satellite already in orbit is or when it passes overhead.

Input parameters:

- `language` (string): The language of the answer and of the page it links: en (the default) or es

### `close_approaches` (~179 tokens)

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 where one is stated, and the two objects named. Coming ones first, then those of the last thirty days. Call it when asked whether satellites are about to collide, what is close to the ISS, or what is happening in orbit this week. It lists close approaches alone: the manoeuvres, breakups and rendezvous of the same window are on the Events page, not here. It cannot predict approaches Space-Track has not reported, and a reported approach is rarely a collision.

Input parameters:

- `language` (string): The language of the answer and of the page it links: en (the default) or es

### `reentries` (~160 tokens)

Re-entries

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 catalogue dates its re-entry. Satellites, rocket bodies and debris alike, named as the catalogue names them. Call it when asked what is about to fall from orbit, whether a named object has re-entered, or what came down recently. It cannot say where anything will fall or fell: Space-Track publishes no place, only a time window or a day.

Input parameters:

- `language` (string): The language of the answer and of the page it links: en (the default) or es

### `crew` (~142 tokens)

Who is aboard the stations

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 changes of the last two days. Call it when asked who is in space, who is on the ISS, how many people are in orbit, or who is aboard Tiangong. Takes no parameters beyond the language. It does not know where a station is now and lists nobody outside a station.

Input parameters:

- `language` (string): The language of the answer and of the page it links: en (the default) or es

### `census` (~121 tokens)

Satellites in orbit

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 when asked how many satellites there are, how crowded space is, or how much debris is in orbit. Takes no parameters beyond the language. It cannot name or find one satellite.

Input parameters:

- `language` (string): The language of the answer and of the page it links: en (the default) or es
