Time, timezone and duration tools — IANA zones, conversion, DST-correct date arithmetic.
5 tools: 1 do something that can't be undone, 2 change things and 2 only read.
- Reads private data · 1
- Reads text others write · 0
- Can send data out · 1
- No findings
Anlyon alternative
3 of these tools change something. Run those as governed actions.
Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.
Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

Can't be undone 1Claude Code: ask
time_betweenExact elapsed time between two ISO-8601 timestamps, broken into days/hours/minutes/seconds plus a human-readable summary.Can send data outNo findings
Why it is in this group
- The input addresses people (input.to): what it sends cannot be taken back.
What it can reach
- outboundThe input takes a destination (input.to): what the tool writes goes there.
Description, as the server wrote it Exact elapsed time between two ISO-8601 timestamps, broken into days/hours/minutes/seconds plus a human-readable summary. All components share one sign, so they sum correctly; `direction` is 'past', 'future', or 'same'.
Changes things 2Claude Code: ask
add_durationAdd an ISO-8601 duration to a timestamp, in a timezone.No findings
Why it is in this group
- The name "add_duration" says "add": a word for a change.
Description, as the server wrote it Add an ISO-8601 duration to a timestamp, in a timezone. Date units (Y/M/D) are calendar-aware: P1D across a DST boundary keeps the same wall-clock time the next day, and P1M on Jan 31 clamps to the end of February. Time units (H/M/S) are exact elapsed time, so PT24H really is 24 hours. Prefix the duration with '-' to subtract.
convert_timezoneRender an ISO-8601 timestamp as wall-clock time in a target timezone.No findings
Why it is in this group
- The name "convert_timezone" says "convert": a word for a change.
Description, as the server wrote it Render an ISO-8601 timestamp as wall-clock time in a target timezone.
Only reads 2Show 2 read-only tools
get_current_timeReturn the current time as an epoch, a UTC ISO-8601 timestamp, and the wall-clock time in a given timezone.No findings
Why it is in this group
- The name "get_current_time" says "get": a word for reading.
Description, as the server wrote it Return the current time as an epoch, a UTC ISO-8601 timestamp, and the wall-clock time in a given timezone.
infoReturns identity and build information for this server (name, version, build commit, runtime, capability counts)Reads private dataNo findings
Why it is in this group
- The description's first verb is "return": a word for reading.
What it can reach
- private-dataThe description's first sentence says "return" and "commit": it reads repositories.
Description, as the server wrote it Returns identity and build information for this server (name, version, build commit, runtime, capability counts)
This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
Exfil surface
Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.
No private-data, untrusted-input, outbound path in this server alone: no tool is tagged untrusted-input.
- Reads text others write0
- Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
- Can send data out1
- Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.
Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.
Findings
Matches of fixed checks, with the text they matched.
No check matched anything in these tool definitions. That is not a safety guarantee.
History
Changes to its tool definitions and to its remote endpoint, newest first.
No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.
Install
Pinned to version 0.2.3. Values in angle brackets are yours to fill in.

Claude Code permissions
Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.
{
"permissions": {
"allow": [
"mcp__temporal__info",
"mcp__temporal__get_current_time"
],
"ask": [
"mcp__temporal__convert_timezone",
"mcp__temporal__add_duration",
"mcp__temporal__time_between"
],
"deny": []
}
}Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as temporal. Review it before you use it.
Capability tags behind 2 rules
- mcp__temporal__info private-data
- mcp__temporal__time_between outbound
Pin
Keep the decision: fail CI when the tools change, follow every change, or show a badge.
Pin in CI
Fail a build when the tools you reviewed are not the tools the server serves today.
