## 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__professionalheadshot__get_profile_photo_specs` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__professionalheadshot__audit_headshot` `mcp__professionalheadshot__get_headshot_guide` |
| 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 (1)

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

### `audit_headshot`

- 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
Score one photo 0-100 as a professional headshot and list concrete issues and fixes (lighting, framing, face visibility, background, attire). Takes a public https URL to a JPEG/PNG/WebP image. Free: 5 audits per day per user. The photo is analysed and not stored.
```

## Only reads (2)

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

### `get_headshot_guide`

- The name "get_headshot_guide" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "website": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
How to shoot or choose a professional headshot for a given use (LinkedIn, resume/CV, company website team page, executive bio, speaker/press kit) and industry: framing, background, attire, expression and what to avoid. Style guidance, not an official platform rule.
```

### `get_profile_photo_specs`

- The name "get_profile_photo_specs" says "get": a word for reading.
- Tag private-data: The description's first sentence says "file": it reads files.

Description, as the server wrote it:

```untrusted-server-text
Official profile and cover photo requirements (pixel limits, file size, formats, content rules) for LinkedIn personal profiles, LinkedIn company Pages, Slack and GitHub, quoted from each platform's help pages with source links. Values the platform does not publish are null. Omit platform to get all.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__professionalheadshot__get_profile_photo_specs",
      "mcp__professionalheadshot__get_headshot_guide"
    ],
    "ask": [
      "mcp__professionalheadshot__audit_headshot"
    ],
    "deny": []
  }
}
```

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

- `mcp__professionalheadshot__get_profile_photo_specs`: private-data
- `mcp__professionalheadshot__get_headshot_guide`: untrusted-input
- `mcp__professionalheadshot__audit_headshot`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:08:47.865Z, unchanged since 2026-10-22T15:08:47.865Z. 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` |

| RFC 9728 protected resource metadata | `none` |
| Authorization servers | `none` |

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

https://professionalheadshot.io/api/mcp: tools/list returned 3 tools to an anonymous client, including audit_headshot (write)
