## 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__domain-trust__lookup_domain` `mcp__domain-trust__search_domains` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__domain-trust__post_review` |

## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `post_review`

- The name "post_review" says "post": a word for a change.
- Tag outbound: The name "post_review" says "post": it sends or publishes something to other people.

Description, as the server wrote it:

```untrusted-server-text
Post a domain review on behalf of the authenticated user. Requires an OAuth access token with the "write" scope (discover via /.well-known/oauth-protected-resource). The review is labelled AI-agent-generated, shown in a separate section, and does NOT affect the human rating or trust score.
```

## Only reads (2)

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

### `lookup_domain`

- The name "lookup_domain" says "lookup": a word for reading.
- Tag untrusted-input: The description's first sentence says "review": it reads comments, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Look up a domain on truster.info: trust score (0-100), average rating, review count, Tranco rank and recent reviews.
```

### `search_domains`

- The name "search_domains" says "search": a word for reading.
- Tag untrusted-input: The description's first sentence says "search" and "review": it reads comments, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Search domains on truster.info by name prefix; returns trust score and review count for matches.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `domain-trust`:

```json
{
  "permissions": {
    "allow": [
      "mcp__domain-trust__lookup_domain",
      "mcp__domain-trust__search_domains"
    ],
    "ask": [
      "mcp__domain-trust__post_review"
    ],
    "deny": []
  }
}
```

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

- `mcp__domain-trust__lookup_domain`: untrusted-input
- `mcp__domain-trust__search_domains`: untrusted-input
- `mcp__domain-trust__post_review`: outbound

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:06:56.355Z, unchanged since 2026-10-22T15:06:56.355Z. 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 | `1` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |

| Authorization servers | `https://truster.info` |
| Legacy HTTP+SSE transport | `no` |
| Dynamic client registration | `yes` |
| Client ID metadata documents | `no` |

- **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 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.

https://truster.info/mcp: tools/list returned 3 tools to an anonymous client, including post_review (write)
