## 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__glassypic__optimize_image` `mcp__glassypic__status` `mcp__glassypic__upgrade` |
| 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.

### `optimize_image`

- 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
Optimize an image: smart lossy compression (typically 60-80% size reduction), optional resize/upscale/format conversion, and AI-generated SEO metadata. Accepts absolute local file paths or remote URLs. In remote/API mode, only remote URLs are supported. Supported input formats: JPG, PNG, WebP, AVIF, GIF, SVG, ICO, HEIC, TIFF, BMP (max 50 MB). Supported output formats: JPG, PNG, WebP, AVIF, GIF, SVG, ICO. Credits: 3 to compress (always), +1 if width or height is set, +2 to upscale, +1 for SEO tags (on by default). A full pipeline is 7 credits. Upscale is charged whether you request it or the server adds it automatically — it does so whenever a resize target exceeds the source by more than 1.2x, so a resize-only call on a small image also costs 7. SVG or ICO output is a flat 1 credit, overriding everything above. Animated GIFs are billed per frame: (per-frame operations x frames) + 1 if tags, up to 601 credits at the 100-frame limit — confirm_gif_cost gates that path. GIFs are excluded from automatic upscaling. Works as a guest with no signup. Log in with the login tool for more credits. Use status tool to check remaining credits before batch processing.
```

### `upgrade`

- The description's first verb is "open": 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
Open the GlassyPic pricing page in the user's browser, where the account's plan can be reviewed and changed. Call this only when the user asks to change or review their plan.
```

## Only reads (1)

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

### `status`

- The name "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
Check your GlassyPic account status: login state, tier, credits remaining, and credit reset time. Use this before batch processing to verify sufficient credits.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__glassypic__status"
    ],
    "ask": [
      "mcp__glassypic__optimize_image",
      "mcp__glassypic__upgrade"
    ],
    "deny": []
  }
}
```

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

- `mcp__glassypic__optimize_image`: untrusted-input
- `mcp__glassypic__status`: untrusted-input
- `mcp__glassypic__upgrade`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:03:34.782Z, unchanged since 2026-10-22T15:03:34.782Z. 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 | `2` |
| 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 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

https://app.glassypic.com/mcp: tools/list returned 3 tools to an anonymous client, including optimize_image (write), upgrade (write)
