## Exfil surface

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

| 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. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Only reads (3)

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

### `get_current_reading`

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

Description, as the server wrote it:

```untrusted-server-text
Today's Gold Barometer reading: the 0-100 gold buying-conditions score, its zone, and the state of each measured part. Updated daily after the US market closes. A free email goes out each time the reading moves to a new zone; the result carries the sign-up address. It measures conditions. It is not advice, and it does not predict the price.
```

### `get_reading_history`

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

Description, as the server wrote it:

```untrusted-server-text
Past Gold Barometer readings, oldest first. Daily published readings by default; set include_reconstructed to true to add month-end context rows rebuilt back to 2019. The monthly record back to 1971 lives in the public archive.
```

### `get_zone_record`

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

Description, as the server wrote it:

```untrusted-server-text
What followed months that read like a given zone, across the reconstructed record since 1971: median gold move 1 and 5 years later, before and after inflation, with the month count behind each figure. It measures conditions. It is not advice, and it does not predict the price.
```
