## 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__deckextract__deckextract` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__deckextract__deckextract` |

## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `deckextract`

- 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.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Extract a deck from a DocSend or Papermark sharing link. Returns a temporary download URL and a readable `deckextract://deck/...` resource for the PDF/PPTX (or a ZIP for data rooms — a DocSend Space or Papermark data room counts as one extraction like any other link). Pass `analyze: true` (part of DeckExtract for Funds) to also return structured deck data. Decks that email the viewer a verification step return resume tokens with retry instructions: fetch the emailed 6-digit code and retry with `otp` + `otpSessionId` (Papermark), or retry with `url` set to the emailed confirmation link + `sessionId` (DocSend). Typical extraction takes 15-90 seconds; the public API is rate limited to 5 extractions per IP per 30 minutes.
```

## Only reads (1)

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

### `account_status`

- The name "account_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns the calling account's plan (free or Pro), whether it's signed in, and this month's extraction usage and remaining quota. Takes no input.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__deckextract__account_status"
    ],
    "ask": [
      "mcp__deckextract__deckextract"
    ],
    "deny": []
  }
}
```

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

- `mcp__deckextract__deckextract`: untrusted-input, outbound

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:30:31.876Z, unchanged since 2026-10-22T14:30:31.876Z. 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://deckextract.com/.well-known/oauth-protected-resource/mcp` |
| Authorization servers | `https://oszhmiypdhslydimpvwi.supabase.co/auth/v1` |
| Legacy HTTP+SSE transport | `no` |
| Dynamic client registration | `yes` |
| Client ID metadata documents | `no` |

- **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 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.

https://deckextract.com/mcp: tools/list returned 2 tools to an anonymous client, including deckextract (write)
```
