**3 tools: 1 do something that can't be undone and 2 only read.**

## 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__share-html__describe_share_html` `mcp__share-html__get_public_share` |
| 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.


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `create_share`

- The name "create_share" says "create": a word for a change.
- The description's first verb is "publish": a word for a change that another call does not undo.

Description, as the server wrote it:

```untrusted-server-text
Publish one HTML page as either an unlisted or access-key protected sandboxed share.
```

## Only reads (2)

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

### `describe_share_html`

- The name "describe_share_html" says "describe": a word for reading.
- Tag untrusted-input: The name "describe_share_html" says "describe" and "html": it reads web pages, which anyone can write. The description's first sentence says "return" and "html": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Return the AI-readable Share HTML guide, including routes and safety model.
```

### `get_public_share`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch public metadata for a Share HTML slug.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__share-html__describe_share_html",
      "mcp__share-html__get_public_share"
    ],
    "ask": [
      "mcp__share-html__create_share"
    ],
    "deny": []
  }
}
```

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

- `mcp__share-html__describe_share_html`: untrusted-input
- `mcp__share-html__get_public_share`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:01:52.262Z, unchanged since 2026-10-22T15:01:52.262Z. 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` |
| resource_metadata in WWW-Authenticate | `none` |
| RFC 9728 protected resource metadata | `https://share-html.zhenjiazhou0127.workers.dev/.well-known/oauth-protected-resource` |
| Authorization servers | `https://hihvtuyweqxnsmqmegdt.supabase.co/auth/v1` |
| 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 1 tool that changes things (1 irreversible). Whether a call also works without credentials was not tested: tools are never called.

https://share-html.zhenjiazhou0127.workers.dev/mcp: tools/list returned 3 tools to an anonymous client, including create_share (irreversible)
```
