## 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__readnpick__create_claim` |

## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `check_coverage`

- 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
Check if EU261/EC261 applies to a route (departure or arrival in EU/EEA).
```

### `create_claim`

- The name "create_claim" says "create": a word for a change.
- Tag outbound: The input takes a destination (input.phone): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Submit a flight compensation claim (EU261). reservation_number = PNR (6-7 alphanumeric). flight_datetime 'YYYY-MM-DD HH:MM'. Returns confirmation.
```

## Only reads (3)

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

### `get_airline`

- The name "get_airline" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Look up an airline by IATA code (e.g. 'AF', 'LH') or name. Returns name, IATA, ICAO.
```

### `get_compensation`

- The name "get_compensation" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Estimate EU261 flight compensation (EUR 250/400/600) eligibility for delay/cancellation/denied_boarding. Indicative; final decision by claim partner.
```

### `get_distance`

- The name "get_distance" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Flight distance in km between two airports (IATA code like 'VNO' or city/airport name).
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__readnpick__get_distance",
      "mcp__readnpick__get_compensation",
      "mcp__readnpick__get_airline"
    ],
    "ask": [
      "mcp__readnpick__check_coverage",
      "mcp__readnpick__create_claim"
    ],
    "deny": []
  }
}
```

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

- `mcp__readnpick__create_claim`: outbound

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:39:18.006Z, unchanged since 2026-10-22T14:39:18.006Z. 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 | `2` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |
| RFC 9728 protected resource metadata | `none` |

- **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 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

https://mcp.readnpick.com/mcp: tools/list returned 5 tools to an anonymous client, including check_coverage (write), create_claim (write)
