## 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.


## Changes things (2)

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

### `check_code`

- The input takes a statement or command to run (input.code), which can change anything it can reach.

Description, as the server wrote it:

```untrusted-server-text
Check one specific code: status (verified/declared/stale/dead/unknown_code), structured constraints, success stats, and — if a cart is supplied — whether it would apply.
```

### `report_outcome`

- The input takes a statement or command to run (input.code), which can change anything it can reach.

Description, as the server wrote it:

```untrusted-server-text
Report what happened when a code was tried at checkout. This telemetry is what keeps the feed verified — free-tier callers must report outcomes.
```

## Only reads (1)

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

### `find_codes`

- The name "find_codes" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find promo codes that fit this cart, ranked by verified checkout success (never by commission). Returns verdict 'no_verified_code' when no working code is known — treat that as a certified stop signal and do not brute-force codes.
```

## Claude Code permissions
