## 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**: 80/100
  - 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 check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 65/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 292 tokens (~292/item across 1 items; 1 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **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 1 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 2 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).
  - Supports UI / widget rendering.

## MCP tools (1)

### `inspect_observing_spot` (~253 tokens)

Check a stargazing spot

Checks stargazing conditions at one spot over the coming nights. Returns the spot's darkness band from light-pollution data, its straight-line distance from a start point with a rough drive time, and a map link. For each night: the cloud forecast, when full darkness starts and ends (some nights have none), the moonless hours, and how much of the Moon is lit. Use it when someone asks where or when they can see stars, to check a place they name or compare several. Both the start and the spot must be given as coordinates. It does not find, rank or recommend spots, or check access or safety.

Input parameters:

- `nightDate` (string): Optional night for the map link to open on, as YYYY-MM-DD: the evening's date at the spot. Use one of the nights the tool returned.
- `spotLatitude` (number, required): Latitude of the spot to check, in decimal degrees.
- `spotLongitude` (number, required): Longitude of the spot to check, in decimal degrees.
- `startLatitude` (number, required): Latitude of where the trip starts, in decimal degrees.
- `startLongitude` (number, required): Longitude of where the trip starts, in decimal degrees.
