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 Security89
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation is enforced on tool calls, but the challenge carries no valid RFC 9728 metadata, so a client cannot discover where to get a token. See how to fix → View diagnostics → Fail
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability85
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1634 tokens (~125/item across 13 items; 11 tools + 2 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management40
- Stability observed for 12 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 11 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 12 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 io.github.theluckystrike/timezone-world-clock-meeting-slots… MCP server?
io.github.theluckystrike/timezone-world-clock-meeting-slots… is a hosted endpoint at https://mcp.zovo.one/mcp/timezone, 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.

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 →
business_days Count business days ~159
Count business days between two dates in a place, inclusive, with the calendar total and the weekend and holiday counts. It has NO holiday calendar: without holidays, only weekends are excluded.

Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
contacts_set Save a contact's zone ~107
Save one person's zone and working hours so later calls can name them. Returns the resolved zone and their local time now. Saving the same name REPLACES that contact and says so. Free: 5 contacts.

| earliest_date | string | – | First date to consider, YYYY-MM-DD, default today |
| limit | integer | – | How many slots to return, default 8. Slots are ranked by fairness: the score is the WORST participant's distance in hours from 13:00 local, so a slot that is 07:00 for one person never outranks one t… |
| participants | array | yes | Who has to attend. A zone is OPTIONAL per person: a saved contact supplies their own, and anyone left without one (you, typically) takes the timezone on your shared business profile, so never ask the… |
| recurring | boolean | – | Pro: also report the weekly recurring times that work on every searched weekday |
No output schema declared.
No examples provided.
ics_create Write a calendar invite ~345
Call this tool to write a .ics for one meeting and return the path plus the start in UTC and in your zone. Times are stored in UTC so it lands correctly in any client. Free: 3 files a month.
| Name | Type | Req | Description |

| location | string | – | Where, or a meeting link |
| organizer_email | string | – | Your email address, written as the ORGANIZER so replies have somewhere to go. Leave it out and your shared business profile's email is used; with neither, the ORGANIZER line is omitted rather than fi… |
| organizer_name | string | – | Your display name for the ORGANIZER line |
| out_path | string | – | Name for the downloaded file, default meeting.ics |
| start | string | yes | Start time, read in `zone` unless it carries an offset |
| title | string | yes | Event title |
| zone | string | yes | Place the start time is given in |
No output schema declared.
No examples provided.
license_activate Activate license ~76
Turn Pro on for this connection with key, an MCPL1.<payload>.<signature> issued at checkout for this server or the bundle. Data under your token stays; a wrong or expired key changes nothing. license_status confirms it.

| Name | Type | Req | Description |
|---|---|---|---|
| date | string | – | Date to compute on, YYYY-MM-DD, default today |
| work_end | string | – | Local working day end, default 17:00 |
