## 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__discord-servers__check_invite` |

## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "check_invite" says "invite": a word for sending, and what is sent cannot be taken back.
```


## Can't be undone (1)

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

### `check_invite`

- The name "check_invite" says "invite": a word for sending, and what is sent cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag outbound: The name "check_invite" says "invite": it sends or publishes something to other people.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Look up a Discord invite link or code (discord.gg/abc, discord.com/invite/abc, or just abc). Says whether disdex last saw it working (live), confirmed it dead, is still checking it (pending), or has never seen it (unknown), and which server it leads to, including dead invites, together with other working invites for that server when known.
```

## Only reads (4)

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

### `get_server`

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

Description, as the server wrote it:

```untrusted-server-text
Full details for one Discord server: description, member/online/boost counts, language, guild tag, Discord features, invite link, and how its member count changed over the last 30 days.
```

### `get_server_activity`

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

Description, as the server wrote it:

```untrusted-server-text
Daily member and online counts for one Discord server over a time window, for questions like "is this server growing?" or "how big was it in March?". Values are daily averages of disdex's scans.
```

### `get_stats`

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

Description, as the server wrote it:

```untrusted-server-text
How many Discord servers, users, bots, games and invites disdex has indexed, and when those totals were last refreshed.
```

### `search_servers`

- The name "search_servers" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search public Discord servers indexed by disdex. Matches words against the server name, vanity URL, description, profile traits and guild tag. Returns servers sorted by member count unless another sort is chosen, each with its member and online counts, language, and a joinable invite link when one is known. NSFW servers are never returned.
```

## Claude Code permissions

      "mcp__discord-servers__get_server",
      "mcp__discord-servers__get_server_activity",
      "mcp__discord-servers__get_stats"
    ],
    "ask": [
      "mcp__discord-servers__check_invite"
    ],
    "deny": []
  }
}
```
