## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__spoken__get_balance` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__spoken__get_balance` `mcp__spoken__get_transcript` `mcp__spoken__list_episodes` `mcp__spoken__list_new_episodes` `mcp__spoken__search_podcasts` |
| 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 (2)

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

### `follow_podcast`

- 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
Declare a follow for a show, or clear a mute. Pass a podcast_id from search_podcasts. A declared follow stays until unfollow_podcast, regardless of fetch activity, and does not use one of the five automatic slots. For a show never fetched, what counts as new starts from its newest episode now. Does not consume credits.
```

### `unfollow_podcast`

- 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
Mute a show: it leaves the followed list and later fetches do not re-add it. follow_podcast reverses it. Pass a podcast_id from list_following. Does not consume credits.
```

## Only reads (6)

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

### `get_balance`

- The name "get_balance" says "get": a word for reading.
- Tag private-data: The description's first sentence says "email": it reads mail.
- Tag untrusted-input: The description's first sentence says "email": it reads inbound email, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Check the current Spoken credit balance, account email, and recent usage for the configured API key. Does not consume credits.
```

### `get_transcript`

- The name "get_transcript" 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
Fetch a podcast episode's transcript as clean Markdown with real speaker names and timestamps. Pass an episode id from search_podcasts. Costs 1 credit on the first fetch of an episode; repeat fetches are free and errors are never charged.
```

### `list_episodes`

- The name "list_episodes" says "list": 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
List a podcast's entire back-catalog (every episode, newest first). Pass a podcast_id from a search_podcasts result. Returns each episode's id, title, and date — fetch any with get_transcript. Use this to transcribe a whole show. Does not consume credits itself; transcribing the returned episodes costs 1 credit each (repeat fetches are free), so make sure the key has enough credits before looping.
```

### `list_following`

- The name "list_following" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The shows this key is kept current on. Every charged fetch makes its show a follow: the five most-fetched shows from the last 180 days are followed automatically (source 'fetch'), and up to 25 more can be declared with follow_podcast (source 'explicit'). Muted shows are listed separately. Use list_new_episodes to see what is new on them. Does not consume credits; the demo key has nothing to follow with.
```

### `list_new_episodes`

- The name "list_new_episodes" says "list": a word for reading.
- Tag untrusted-input: The description's first sentence says "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
What is new on the shows this key follows: for each show, the episodes released in the last 90 days that are newer than the newest one already fetched from it (up to 10 per show), each with a transcript_url. Episodes with no transcript are left out. Fetch any with get_transcript (1 credit each on first fetch); a fetch raises that show's floor, so the next call lists only what came after. Refreshed hourly, so a show followed moments ago may be empty until its first poll. Does not consume credits.
```

### `search_podcasts`

- The name "search_podcasts" says "search": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "search" and "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Search published podcast episodes by text query, or paste an episode URL (Spotify, YouTube, etc.). Returns matching episodes with their id, title, podcast, podcast_id, and date. Use the id with get_transcript, or the podcast_id with list_episodes to get the show's whole back-catalog. Does not consume credits.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__spoken__search_podcasts",
      "mcp__spoken__get_transcript",
      "mcp__spoken__list_episodes",
      "mcp__spoken__get_balance",
      "mcp__spoken__list_following",
      "mcp__spoken__list_new_episodes"
    ],
    "ask": [
      "mcp__spoken__follow_podcast",
      "mcp__spoken__unfollow_podcast"
    ],
    "deny": []
  }
}
```

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

- `mcp__spoken__search_podcasts`: untrusted-input
- `mcp__spoken__get_transcript`: untrusted-input
- `mcp__spoken__list_episodes`: untrusted-input
- `mcp__spoken__get_balance`: private-data, untrusted-input
- `mcp__spoken__list_new_episodes`: untrusted-input

- **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://spoken.md/mcp: tools/list returned 8 tools to an anonymous client, including follow_podcast (write), unfollow_podcast (write)
