**3 tools: 3 change things.**

| Group | Class | Tools | Claude Code |

## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input.

| 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. | `mcp__mdapi__extract_page` `mcp__mdapi__html_to_markdown` |

## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `extract_page`

- Nothing in its name or description says what it does, so it is counted as a write.
- 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 structured JSON from a web page (by URL) or raw HTML: title, byline, excerpt, siteName, publishedTime, language, plain text, links, images, and meta tags. Paid tool: $0.005 per call via x402 (USDC on Base).
```

### `html_to_markdown`

- The description's first verb is "convert": a word for a change.
- 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
Convert a web page (by URL) or raw HTML into clean, LLM-ready Markdown. Readability article extraction; nav/scripts/footers stripped; tables preserved. Set render=true to execute the page in a real headless browser first — required for JS-rendered SPAs (React/Next/Vue) that return empty HTML to a plain fetch. Paid tool: $0.005 per call via x402 (USDC on Base).
```

### `service_info`

- 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
Free. Service, pricing, and payment details for the mdapi tools on this server.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__mdapi__html_to_markdown",
      "mcp__mdapi__extract_page",
      "mcp__mdapi__service_info"
    ],
    "deny": []
  }
}
```

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

- `mcp__mdapi__html_to_markdown`: outbound
- `mcp__mdapi__extract_page`: outbound

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:49:01.313Z, unchanged since 2026-10-22T14:49:01.313Z. 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 | `3` |
| Protocol version | `2025-06-18` |
| 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` |

- **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 3 tools that change things (3 write). Whether a call also works without credentials was not tested: tools are never called.

https://md.fastdb.in/mcp: tools/list returned 3 tools to an anonymous client, including html_to_markdown (write), extract_page (write), service_info (write)
