## 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 2026-08-03.

- **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**: 66/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 519 tokens (~103/item across 5 items; 5 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 95/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 85% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (5)

### `get_current_time` (~101 tokens)

Get current time

Get the current local time (or the time at a given instant) in one or more locations. Each location is a city name, an IANA timezone / abbreviation, or coordinates. Up to 50 locations. Results include a source_url linking the matching worldclock.pro page when available.

Input parameters:

- `at` (string): Optional ISO 8601 instant to evaluate instead of now (read as UTC if it has no zone).
- `locations` (array, required)

### `convert_time` (~109 tokens)

Convert a time across locations

Given a UTC instant (or a wall time in a source location), return the corresponding local time in each of up to 50 target locations. Results include a source_url linking the matching worldclock.pro page when available.

Input parameters:

- `from` (object): Alternative to `utc`: a wall time in a specific source location.
- `targets` (array, required)
- `utc` (string): The instant to convert, as an ISO 8601 string. Read as UTC if it has no zone designator.

### `time_by_coordinates` (~88 tokens)

Get time by coordinates

Resolve the timezone for a latitude/longitude coordinate (via geo-tz) and return the local time there.

Input parameters:

- `at` (string): Optional ISO 8601 instant to evaluate instead of now (read as UTC if it has no zone).
- `latitude` (number, required): Latitude in degrees [-90, 90].
- `longitude` (number, required): Longitude in degrees [-180, 180].

### `get_dst_transitions` (~106 tokens)

Get DST transitions

Report whether a location observes daylight saving time, the next clock change, and every summer/winter-time transition (date, local time, and before/after offset) within a year. The result includes a source_url linking the matching worldclock.pro page when available.

Input parameters:

- `location` (object, required): A location identified by exactly ONE of: query, timezone, or latitude+longitude together.
- `year` (integer): Calendar year to list transitions for (default: the current year).

### `search_cities` (~115 tokens)

Search cities

Find cities by name (multilingual, diacritic-insensitive) — useful to resolve a place to a canonical slug, IANA timezone, and coordinates before calling the time tools. Each result includes a source_url linking the city's worldclock.pro page.

Input parameters:

- `country` (string): Optional ISO 3166-1 alpha-2 country filter, e.g. "JP".
- `limit` (integer): Max results (default 10).
- `query` (string, required): City name or partial name (≥ 2 characters).
