**5 tools: 1 do something that can't be undone, 2 change things and 2 only read.**

## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged untrusted-input.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__temporal__info` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__temporal__time_between` |

## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `time_between`

- The input addresses people (input.to): what it sends cannot be taken back.
- Tag outbound: The input takes a destination (input.to): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
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 (2)

Creates or changes something that can be changed back. Claude Code: ask.

### `add_duration`

- The name "add_duration" says "add": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
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_timezone`

- The name "convert_timezone" says "convert": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Render an ISO-8601 timestamp as wall-clock time in a target timezone.
```

## Only reads (2)

Looks things up and changes nothing. Claude Code: allow.

### `get_current_time`

- The name "get_current_time" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return the current time as an epoch, a UTC ISO-8601 timestamp, and the wall-clock time in a given timezone.
```

### `info`

- The description's first verb is "return": a word for reading.
- Tag private-data: The description's first sentence says "return" and "commit": it reads repositories.

Description, as the server wrote it:

```untrusted-server-text
Returns identity and build information for this server (name, version, build commit, runtime, capability counts)
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `temporal`:

```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": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__temporal__info`: private-data
- `mcp__temporal__time_between`: outbound
