## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__translate__proxylang_next` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__translate__proxylang_change_site` `mcp__translate__proxylang_check` `mcp__translate__proxylang_next` `mcp__translate__proxylang_start` `mcp__translate__proxylang_status` `mcp__translate__proxylang_style` |
| 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 (4)

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

### `proxylang_change_site`

- Nothing in its name or description says what it does, so it is counted as a write.
- 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
Use when the trial was started for the wrong website (action "move": the old site stops), or the tag must also work on a test or staging site (action "add": both work). Same agent_token, script tag, claim_url and free words; all sites share one limit. Not needed for localhost: use localhost_script_tag.
```

### `proxylang_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 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
Is the Proxylang tag on the live site, and have words been translated? If words_translated is 0, a real browser visit to preview_url is needed first.
```

### `proxylang_start`

- The name "proxylang_start" says "start": 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
Set up Proxylang on a website with no signup: returns the script tag, install steps for the site's platform, an agent_token for the other tools, and claim_url (sent once; save it). If the user named a language, use it; otherwise pick the one their customers most likely speak and say why. The free trial shows the first language; list other recommended languages after it.
```

### `proxylang_style`

- Nothing in its name or description says what it does, so it is counted as a write.
- 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
Restyle the language menu so it looks like part of the site. Read the site's brand color, background, text color, button roundness and dark mode first, then send only the fields to change in `style`. Colors: #hex, rgb(), hsl() or a CSS color name; each has a Light and a Dark version. Full field list: https://proxylang.dev/agents.md step 7.
```

## Only reads (2)

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

### `proxylang_next`

- The description's first verb is "return": a word for reading.
- Tag private-data: The description's first sentence says "return" and "message": it reads messages.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "return" and "message": it reads messages, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Returns message_for_user: the message to end setup with (the site works, the link to keep it, and only the Proxylang features that fit this site). Show it as it is, in the user's language, with <claim_url> replaced by the saved claim_url.
```

### `proxylang_status`

- The name "proxylang_status" says "status": a word for reading.
- 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
Free words left, trial expiry, and whether the user claimed or paid.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__translate__proxylang_next",
      "mcp__translate__proxylang_status"
    ],
    "ask": [
      "mcp__translate__proxylang_start",
      "mcp__translate__proxylang_check",
      "mcp__translate__proxylang_change_site",
      "mcp__translate__proxylang_style"
    ],
    "deny": []
  }
}
```

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

- `mcp__translate__proxylang_start`: untrusted-input
- `mcp__translate__proxylang_check`: untrusted-input
- `mcp__translate__proxylang_next`: private-data, untrusted-input
- `mcp__translate__proxylang_status`: untrusted-input
- `mcp__translate__proxylang_change_site`: untrusted-input
- `mcp__translate__proxylang_style`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:46:33.290Z, unchanged since 2026-10-22T14:46:33.290Z. 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 |
| --- | --- |
| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `4` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |
| 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 4 tools that change things (4 write). Whether a call also works without credentials was not tested: tools are never called.

https://proxylang.dev/mcp: tools/list returned 6 tools to an anonymous client, including proxylang_start (write), proxylang_check (write), proxylang_change_site (write), proxylang_style (write)
