Available components
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. How we score → Why this is hard to score →
Endpoint Security83
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability75
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 519 tokens (~103/item across 5 items; 5 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage95
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 85% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the pro.worldclock/time MCP server?
pro.worldclock/time is a hosted endpoint at https://worldclock.pro/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

No change was recorded against any check on this day. Stability & Change Management went from 90 to 93. That category is still filling its 30-day observation window: 27 days of observed history at the previous scan, 28 at this one. The score rises as the window fills, whether or not the server changes.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
convert_time Convert a time across locations ~109
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.
| Name | Type | Req | Description |
|---|---|---|---|
| from | object | – | Alternative to `utc`: a wall time in a specific source location. |
| targets | array | yes | – |
| utc | string | – | The instant to convert, as an ISO 8601 string. Read as UTC if it has no zone designator. |
No output schema declared.
No examples provided.
get_current_time Get current time ~101
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.
| Name | Type | Req | Description |
|---|---|---|---|
| at | string | – | Optional ISO 8601 instant to evaluate instead of now (read as UTC if it has no zone). |
| locations | array | yes | – |
No output schema declared.
No examples provided.
get_dst_transitions Get DST transitions ~106
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.
| Name | Type | Req | Description |
|---|---|---|---|
| location | object | yes | 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). |
No output schema declared.
No examples provided.
search_cities Search cities ~115
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.
