## 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__fleetstreet__fleetstreet_get_started` `mcp__fleetstreet__fleetstreet_signup` |
| 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.


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `fleetstreet_signup`

- The description's first verb is "create": a word for a change.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Create a new fleetstreet portfolio site. Requires the human's email and a portfolio/studio name: a welcome + activation email is sent to them (card required via Stripe to start the 7-day free trial, nothing charged during it). Returns an API key (shown once) and unlocks all fleetstreet tools in this session immediately. Ask the human for their email and portfolio name before calling.
```

## Only reads (1)

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

### `fleetstreet_get_started`

- The name "fleetstreet_get_started" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Explains what fleetstreet is and how to activate this MCP server (no API key on this session yet).
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__fleetstreet__fleetstreet_get_started"
    ],
    "ask": [],
    "deny": [
      "mcp__fleetstreet__fleetstreet_signup"
    ]
  }
}
```

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

- `mcp__fleetstreet__fleetstreet_get_started`: untrusted-input
- `mcp__fleetstreet__fleetstreet_signup`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:01:15.213Z, unchanged since 2026-10-22T15:01:15.213Z. 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 | `202` |
| 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` |

- **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 destructive). Whether a call also works without credentials was not tested: tools are never called.

https://mcp.fleetstreet.ai/sse: tools/list returned 2 tools to an anonymous client, including fleetstreet_signup (destructive)
