## 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__image-to-beads__convert_image_to_pattern` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **warn** Annotations that disagree with the tool in `convert_image_to_pattern` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "convert_image_to_pattern" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "convert_image_to_pattern" says "convert": a word for a change.
```

- **warn** Annotations that disagree with the tool in `lookup_bead_color` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "lookup_bead_color" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "lookup_bead_color" says "lookup": a word for reading.
```


## Changes things (2)

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

### `convert_image_to_pattern`

- The name "convert_image_to_pattern" says "convert": a word for a change.
- 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.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Convert a user-provided PNG/JPEG into an editable fuse-bead chart with real MARD color codes, bead counts, PNG and CSV. Free direct conversion, not AI chibi stylization. Process only images the user authorizes; the image is sent to Doucebeads for this request, never persisted. Prefer base64 from an image/file attachment when the client can pass it; do not invent file URLs. At most 750KB and 1 megapixel. Return the free result first; optionally mention the Q-version link only for users who want stylization.
```

### `lookup_bead_color`

- The name "lookup_bead_color" says "lookup": a word for reading.
- The input takes a statement or command to run (input.code), which can change anything it can reach.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Look up a specific MARD bead code; RGB values are community approximations, not official calibrated measurements.
```

## Only reads (1)

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

### `get_conversion_guide`

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

Description, as the server wrote it:

```untrusted-server-text
Get supported image formats, privacy, request limits, and links to free chart printing or optional paid chibi styling. No image is uploaded by this call.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `image-to-beads`:

```json
{
  "permissions": {
    "allow": [
      "mcp__image-to-beads__get_conversion_guide"
    ],
    "ask": [
      "mcp__image-to-beads__convert_image_to_pattern",
      "mcp__image-to-beads__lookup_bead_color"
    ],
    "deny": []
  }
}
```

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

- `mcp__image-to-beads__convert_image_to_pattern`: untrusted-input
