## 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__atc__asset_calls` `mcp__atc__speaker_calls` `mcp__atc__topic_timeline` |

## Findings

- **warn** Annotations that disagree with the tool in `topic_timeline` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "topic_timeline" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The input addresses people (input.to): what it sends cannot be taken back.
```

- **warn** Annotations that disagree with the tool in `speaker_calls` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "speaker_calls" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "speaker_calls" says "call": a word for a change.
```

- **warn** Annotations that disagree with the tool in `asset_calls` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "asset_calls" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "asset_calls" says "call": a word for a change.
```

- **warn** Annotations that disagree with the tool in `calls_leaderboard` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "calls_leaderboard" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "calls_leaderboard" says "call": a word for a change.
```


## Can't be undone (3)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `asset_calls`

- The name "asset_calls" says "call": a word for a change.
- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag outbound: The input takes a destination (input.to): what the tool writes goes there.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Who called an asset on ATC, when, which direction and the result (from the ATC leaderboard), newest first.
```

### `speaker_calls`

- The name "speaker_calls" says "call": a word for a change.
- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag outbound: The input takes a destination (input.to): what the tool writes goes there.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
A speaker's on-air ATC calls and their record (calls, hits, misses, not scored), newest first, each with quote, date, asset, direction, level, result and share link. Results come from the ATC leaderboard.
```

### `topic_timeline`

- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag outbound: The input takes a destination (input.to): what the tool writes goes there.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
How a subject came up on ATC over time: every matching segment in date order (oldest first) with what was said, who said it and links. Good for 'how has the show's view on X changed'.
```

## Changes things (2)

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

### `calls_leaderboard`

- The name "calls_leaderboard" says "call": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
ATC calls leaderboard, same rule as atcspaces.com: speakers with at least 20 scored calls (hit or miss) ranked by hit rate, ties broken by total hits. Everyone else is listed separately as not enough scored calls yet.
```

### `speaker_profile`

- 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
An ATC speaker by name or X handle: appearances, first and last show, what they talk about most, and their recent segments.
```

## Only reads (7)

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

### `fetch`

- The name "fetch" says "fetch": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read a show segment (id from search: summary plus a transcript excerpt) or an episode (Space id or YYYY-MM-DD date: summary, chapters and segment ids to fetch).
```

### `get_episode`

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

Description, as the server wrote it:

```untrusted-server-text
One ATC show by date (YYYY-MM-DD) or Space id: summary, speakers, tags, timestamped chapters and links.
```

### `list_episodes`

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

Description, as the server wrote it:

```untrusted-server-text
List ATC shows, newest first, optionally filtered by date range, tag (e.g. 'btc', 'stablecoins', 'nfts') or speaker.
```

### `search`

- The name "search" says "search": a word for reading.

Description, as the server wrote it:

```

### `search_transcripts`

- The name "search_transcripts" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Exact-word search across every ATC transcript line. Returns quotes with speaker, X handle, timestamp, surrounding lines and episode link. Best for 'who said X' and quotes.
```

Description, as the server wrote it:

```untrusted-server-text
When ATC is live, who hosts it, the regular panel, how to come on the show, and archive coverage.

## Claude Code permissions

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

```json

  "permissions": {
    "allow": [
      "mcp__atc__show_info",
      "mcp__atc__search",
      "mcp__atc__fetch",
