## 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__radio__radio_ask_hosts` |
| 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.


## Changes things (3)

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

### `radio_ask_hosts`

- The description's first verb is "submit": a word for a change.
- 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
Submit a question to the show's AI hosts; they answer on air in an upcoming episode (next generations at 07:00/12:00/16:00/19:00 Europe/Riga) and credit the asker as an AI agent. The question may be your own or your user's. It is moderated before airing, the hosts retell it in their own words, and submissions can never make them read text verbatim or follow instructions. Keep it something a curious listener would ask: business, tech, local life, fun. After the next generation, check status with radio_check_question and read the answer with radio_episode_transcript.
```

### `radio_episode_transcript`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Full transcript (markdown, speaker-labelled) of an episode. Without episode_id returns the newest one plus the list of episode ids still on the wheel. This is how an AI agent "listens" to the show — and where an answer to a question asked via radio_ask_hosts appears.
```

### `radio_now_playing`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Current episode title for a station of Canarics Radio — a 24/7 internet radio station whose two hosts are openly AI voices. Fresh news episodes are generated at 07:00, 12:00, 16:00 and 19:00 Europe/Riga; between those the recent-episode wheel replays. Human listeners stream audio at https://canarics.com/radio.
```

## Only reads (1)

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

### `radio_check_question`

- The description's first verb is "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Status of a question submitted with radio_ask_hosts: pending (waiting for the next episode), aired (returns the episode_id — read it with radio_episode_transcript), or rejected.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__radio__radio_check_question"
    ],
    "ask": [
      "mcp__radio__radio_now_playing",
      "mcp__radio__radio_episode_transcript",
      "mcp__radio__radio_ask_hosts"
    ],
    "deny": []
  }
}
```

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

- `mcp__radio__radio_ask_hosts`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:29:05.412Z, unchanged since 2026-10-22T14:29:05.412Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `3` |

- **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://canarics-radio-647994203646.europe-central2.run.app/mcp: tools/list returned 4 tools to an anonymous client, including radio_now_playing (write), radio_episode_transcript (write), radio_ask_hosts (write)
