## Exfil surface

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

| 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. | `mcp__replyonthefly__write_review_reply` `mcp__replyonthefly__write_review_request_message` |

## Findings

- **warn** Annotations that disagree with the tool in `write_review_reply` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "write_review_reply" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":false,"openWorldHint":false}; The name "write_review_reply" says "write": a word for a change.
```

- **warn** Annotations that disagree with the tool in `write_review_request_message` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "write_review_request_message" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "write_review_request_message" says "write": a word for a change.

## Changes things (2)

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

### `write_review_reply`

- The name "write_review_reply" says "write": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag outbound: The name "write_review_reply" says "write" and "reply": it writes something other people read.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Writes a reply a business owner can post under a customer review on Google, Yelp, Facebook, TripAdvisor or Trustpilot. Use it when someone shares a review of their business and wants a response to it, including angry or negative reviews. The reply follows the star rating: it thanks happy customers, and for low ratings it acknowledges the problem without arguing and offers to make it right. It does not post anything anywhere; the owner copies the reply and posts it themselves. It does not write reviews.
```

### `write_review_request_message`

- The name "write_review_request_message" says "write": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag outbound: The name "write_review_request_message" says "write" and "message": it writes something other people read. The input takes a destination (input.channel): what the tool writes goes there.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Writes short messages a business owner can text or email to a customer to ask for a Google review, adapted to the type of business. Use it when someone wants more Google reviews or asks how to ask a customer for a review. Returns up to three ready-to-send options with the owner's review link at the end. It does not send anything. The messages never offer incentives, which Google prohibits.
```
