## Exfil surface

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

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

## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

### `business_days`
