## 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__php-playground__read_sandbox` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__php-playground__read_sandbox` |

## Findings

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

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

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


## Changes things (1)

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

### `create_sandbox`

- The name "create_sandbox" says "create": a word for a change.
- 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
Creates a shareable link to a playground that runs the given code in the browser (PHP in WebAssembly), with no
account and nothing to install. Give only the files you change or add: the others stay as in the starting
project (see get_starter). Nothing is stored: the code travels inside the link, after the "#". The page asks
the visitor before running code received by a link.
```

## Only reads (2)

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

### `get_starter`

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

Description, as the server wrote it:

```untrusted-server-text
Returns the starting project of a playground (Symfony 8, Laravel 13 or plain PHP 8.5 with Composer autoloading):
its files, the paths you may create or edit, and, for Symfony and plain PHP, the Composer packages you may add. Call it
before create_sandbox to write code that fits the project. Configuration files (config/, bootstrap/) are listed
in config_files; ask for their content with include_config when you need to change one.
```

### `read_sandbox`

- The name "read_sandbox" says "read": a word for reading.
- Tag untrusted-input: The description's first sentence says "read" and "http": it reads web pages, which anyone can write. The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Claude Code: ask, because it is tagged outbound.

Description, as the server wrote it:

```untrusted-server-text
Reads a playground link (https://<site>/bac-a-sable/... or /en/playground/...#code=..., or a short link
/bac-a-sable/s/<id> or /en/playground/s/<id>): returns
the framework and the files that differ from the starting project, to review or fix the code someone shared.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__php-playground__get_starter"
    ],
    "ask": [
      "mcp__php-playground__create_sandbox",
      "mcp__php-playground__read_sandbox"
    ],
    "deny": []
  }
}
```

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

- `mcp__php-playground__read_sandbox`: untrusted-input, outbound
