## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data 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. | `mcp__malwagon__search_indicator` `mcp__malwagon__submit_scan` |
| 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.

### `poll_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.

Description, as the server wrote it:

```untrusted-server-text
The current status of one scan, for polling after submit_scan. Cheap enough to call in a loop. 'terminal' means the scan will not change again; 'report_available' means get_report will return a full report. Answers 'not found' for an unknown scan and an unreadable one identically.
```

### `submit_scan`

- The name "submit_scan" says "submit": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Queue a new analysis of a target that can be named as text: a SHA-256 to look up, a URL to visit, a command to run, or a package to install. Uploading a file or a document is not possible over MCP. This spends the account's own credits and is subject to its plan limits. Poll the returned scan_id with poll_scan, then read it with get_report.
```

## Only reads (3)

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

### `get_report`

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

Description, as the server wrote it:

```untrusted-server-text
The derived analysis report for one scan: verdict, capabilities, behaviour summary, observed operations and defanged indicators. Derived data only - it never contains the sample's bytes, its decompiled source, a download link or an artifact reference. Every list in the result reports what was returned, counted and truncated. Answers 'not found' for a scan that does not exist and for one this token may not read, identically.
```

### `lookup_hash`

- The name "lookup_hash" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find analyses of a known SHA-256 digest. Returns the caller's own scans of those bytes plus any publicly shared scan of them. Sends nothing anywhere: this searches scans that already exist on this platform. Answers with an empty list when the hash is unknown or not visible to this token, without distinguishing the two.
```

### `search_indicator`

- The name "search_indicator" says "search": a word for reading.
- Tag untrusted-input: The description's first sentence says "find" and "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Find scans where an indicator was observed: an IP, a domain, a URL, a mutex, a registry key, a hash or a JA3/JA4 fingerprint. The indicator is matched exactly; defanged input such as 'evil[.]com' is refanged first. Only scans this token may read are searched.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__malwagon__lookup_hash",
      "mcp__malwagon__get_report",
      "mcp__malwagon__search_indicator"
    ],
    "ask": [
      "mcp__malwagon__poll_scan",
      "mcp__malwagon__submit_scan"
    ],
    "deny": []
  }
}
```

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

- `mcp__malwagon__search_indicator`: untrusted-input
- `mcp__malwagon__submit_scan`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:35:59.665Z, unchanged since 2026-10-22T14:35:59.665Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |

| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `2` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |

| RFC 9728 protected resource metadata | `none` |
| Authorization servers | `none` |
| Legacy HTTP+SSE transport | `no` |
| Dynamic client registration | `not observed` |
| Client ID metadata documents | `not observed` |

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

https://malwagon.com/mcp: tools/list returned 5 tools to an anonymous client, including poll_scan (write), submit_scan (write)
