## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input 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. | none |
| 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.


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `delete_story`

- The name "delete_story" says "delete": a word for removing or ending something.
- The description says "cannot be undone".

Description, as the server wrote it:

```untrusted-server-text
Delete a story and all its media (files, versions, logs). This cannot be undone. Use list_stories to find story IDs.
```

## Changes things (5)

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

### `create_story`

- The name "create_story" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Generate a new story from your idea. Creates an illustrated storybook (MD), an AI song, or an AI drama video. Returns a storyId immediately — processing happens in the background. Use get_story to check progress.
```

### `login`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Login to an existing FableMaker account. Returns a JWT token that expires in 26 days. Use this token as Bearer auth for subsequent MCP calls.
```

### `quake_story`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Regenerate a story completely fresh. Same original idea, but creates a brand new version from scratch with new text and media. Like a "do-over". Not available for Model B accounts.
```

### `remix_story`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Turn an existing story into a different format. For example, convert a storybook into a song or video. Uses the same story text — faster and cheaper than creating from scratch. Not available for Model A accounts.
```

### `signup`

- The description's first verb is "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create a new FableMaker account. Returns a JWT token that expires in 26 days. Username must be at least 3 characters, password at least 7 characters with 1 digit.
```

### `buy_credits`

- The description's first verb is "get": a word for reading.

```

### `get_balance`

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

Description, as the server wrote it:

```

### `get_story`

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

Description, as the server wrote it:

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:00:32.961Z, unchanged since 2026-10-22T15:00:32.961Z. 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 | `6` |
| Protocol version | `2025-03-26` |
| 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` |

- **high** 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 6 tools that change things (1 destructive, 5 write). Whether a call also works without credentials was not tested: tools are never called.

https://fable-maker.pendia-community.workers.dev/mcp: tools/list returned 10 tools to an anonymous client, including delete_story (destructive), signup (write), login (write), create_story (write), remix_story (write) and 1 more
