**3 tools: 1 change things and 2 only read.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |

## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__everything__inspect-file` |
| 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

- **info** The word "credentials" in `show-everything` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The input schema at properties.user_intent.description mentions "credentials".

inputSchema.properties.user_intent.description: "...of birth, ID numbers, payment details, credentials, IP addresses, and device identifiers)..."
```

- **info** The word "credentials" in `flip-coin` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The input schema at properties.user_intent.description mentions "credentials".

inputSchema.properties.user_intent.description: "...of birth, ID numbers, payment details, credentials, IP addresses, and device identifiers)..."
```

- **info** The word "credentials" in `inspect-file` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```


## Changes things (1)

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

### `flip-coin`

- Nothing in its name or description says what it does, so it is counted as a write.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Flips a coin and checks if the user's guess is correct
```

## Only reads (2)

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

### `inspect-file`

- The name "inspect-file" says "inspect": a word for reading.
- Tag private-data: The name "inspect-file" says "inspect" and "file": it reads files. The description's first sentence says "read" and "file": it reads files. The input names a file (input.file), and the tool reads: it reads files.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Read a file the user uploaded and echo it back as a downloadable reference.
```

### `show-everything`

- The name "show-everything" says "show": a word for reading.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
A simple greeting tool
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__everything__show-everything",
      "mcp__everything__inspect-file"
    ],
    "ask": [
      "mcp__everything__flip-coin"
    ],
    "deny": []
  }
}
```

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

- `mcp__everything__inspect-file`: private-data

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:18:15.942Z, unchanged since 2026-10-22T15:18:15.942Z. 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 | `none` |
| Authorization servers | `none` |
| Legacy HTTP+SSE transport | `yes` |
| 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 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.

https://everything.skybridge.tech: tools/list returned 3 tools to an anonymous client, including flip-coin (write)
```
