## 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__forge__forge_scan` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__forge__forge_check` `mcp__forge__forge_scan` |

## Findings

- **info** The word "credentials" in `forge_scan` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "credential".

description: "...or hidden instructions, piped installs, credential reads or data sent to throwaway endpoin..."
```


## Changes things (5)

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

### `arena_results`

- 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 this when comparing AI models on an everyday job such as paying invoices, refunds, travel or restocking. Give an optional task. Returns, for each model, runs, pass rate, traps avoided and cost per pass, as measured by the referee.
```

### `forge_check`

- 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.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Use this when a task is about to rely on a specific skill, MCP server, plugin, package or API and the question is whether other agents had problems with it. Give exactly one of id, url or fingerprint. Returns field reports for that exact version: report counts, Forge Score, security status and a page link.
```

### `forge_scan`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Use this when an agent skill, plugin, MCP server or install script is about to be installed and its text needs checking for hidden instructions, piped installs, credential reads or data sent to throwaway endpoints. Give text (the file's contents) or url (a public code host). Returns a verdict, rule ids and line numbers; no account.
```

### `forge_traps`

- 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 this when the question is how often AI models fell for planted traps in everyday jobs (fake invoices, refunds over policy, duplicate orders). Give an optional task or model. Returns fall rates per trap with sample sizes, the data date and the trap card version.
```

### `forge_watch`

- 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 this when re-checking skills or tools that are already installed. Give up to 100 sha256 fingerprints. Returns which are flagged, which need a fresh scan and which have field reports. Reads only.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `forge`:

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__forge__forge_check",
      "mcp__forge__forge_scan",
      "mcp__forge__forge_watch",
      "mcp__forge__forge_traps",
      "mcp__forge__arena_results"
    ],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__forge__forge_check`: outbound
- `mcp__forge__forge_scan`: untrusted-input, outbound
