## 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__moda__check_facebook_group_link` `mcp__moda__search_moda_help` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__moda__send_moda_report` |

## Findings

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

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

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


## Can't be undone (1)

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

### `send_moda_report`

- The name "send_moda_report" says "send": a word for sending, and what is sent cannot be taken back.
- Tag outbound: The name "send_moda_report" says "send": it sends or publishes something to other people. The input takes a destination (input.phone): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Sends a report or request to Moda's team, the same as the form at modacommunities.com/report: a scam, an impersonator or a fake group; a deal dispute; a member conduct problem or ban appeal; group or chat access; a declined post; membership, advertising or billing; or a question for the team.
Moda's team receives it as a case, routed to the right person, and the person gets a case number and a confirmation email. Sending it means the person agrees to Moda's Terms (https://www.modacommunities.com/terms) and Privacy Policy (https://www.modacommunities.com/privacy); when a phone number is included, also to Moda contacting them by phone or text (msg and data rates may apply, reply STOP to opt out).
Required: name, email, category, description and agrees_to_terms. Optional: issue_type (from the category's list), request_type, related_group, phone, facebook_profile, other_party_profile, related_post_link, amount, order_number and reference_check.
Returns JSON with the case number, or the reason it was not sent.
```

## Changes things (5)

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

### `check_facebook_group_link`

- The name "check_facebook_group_link" says "link": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Use when someone has a link to a Facebook group or post and wants to know whether that group is an official Moda group.
link: the facebook.com/groups/... address or a facebook.com/share/... link. Share links are opened on Moda's servers to find the group they point to.
Returns JSON with verdict official, not_official or could_not_check, the group's name when it is official, and a plain sentence to pass on.
```

### `check_listing_words`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use before someone posts a listing in a Moda group, or when their post was declined, to find words that Moda's automatic filters decline.
text: the full listing as it will be posted. group: optional slug of the group it is for; leave it out to check every group.
Returns JSON: each filtered word found, the groups whose filter catches it, words hidden with symbols or spacing, and the other common reasons a post is declined that no word check can see. An empty list means no filtered words, not a guarantee the post goes up.
```

### `check_moda_contact`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use when someone was contacted by a person, number, email or business claiming to be Moda, or wants to know if one is real before trusting it. This is Moda's own scam check, the same one on modacommunities.com/verify.
value: exactly one of an email address, a phone number, a link to a person's Facebook profile, or a business name.
Returns JSON with verdict official, not_official or could_not_check, what was matched (for example a team member's public name and role), a plain sentence summing up the result, and moda_rules: Moda's published wording on what it never asks for in a message. Facebook group and post links are not checked here.
```

### `fix_my_listing`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use when someone's listing has words a Moda group's automatic filter declines, or they ask Moda to fix their post. This is the Post Checker's Fix my post, run on Moda's servers.
text: the listing as written. group: optional slug of the group it is for; leave it out to fix it for every group at once.
Returns JSON: the rewritten listing to copy, each change made (a brand name bent so the filter passes, a word swapped or removed, and why), and any words that stop the post entirely, such as replica terms, where no rewrite is offered.
```

### `look_up_watch_reference`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use when someone gives a watch reference number, such as 126610LN or 5711/1A, and wants to know which watch it is.
reference: the reference number as written.

The endpoint served tools/list without credentials, and the list has 6 tools that change things (1 irreversible, 5 write). Whether a call also works without credentials was not tested: tools are never called.
