## 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__performance-atlas__atlas_search` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__performance-atlas__atlas_buy_pack` |
| 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 (6)

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

### `atlas_buy_pack`

- Nothing in its name or description says what it does, so it is counted as a write.
- 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
Buy 20 paid calls for $1.00 in one x402 payment (USDC on Base). Returns an API key: send it as an `Authorization: Bearer <key>` header (or in params._meta["creatinginai/pack"]) on atlas_kit or atlas_draft instead of paying per call. Each successful call uses one credit; failed calls are free.
```

### `atlas_draft`

- 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
A first-draft acting paragraph assembled from the kit and fitted to the target's character cap, already linted. It reads mechanically: rewrite it as prose. A voice target gets the delivery line instead. Paid: $0.10 per call via x402 (USDC on Base), or prepaid credits with an API key (`Authorization: Bearer <key>`): 20 for $1.00 with atlas_buy_pack, or by card at https://creatinginai.com/agents#credits.
```

### `atlas_journey`

- 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
A character's arc beat by beat, with continuity flags: reset (intensity drops with no event), breach (a hidden feeling shown to the person it's hidden from), overshoot (a tell bigger than the feeling) and flat (beats that never change). Fields a beat leaves out carry over from the beat before. Free.
```

### `atlas_kit`

- 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
The direction kit for a character state: beat-by-beat behaviour fitted to the shot size (where the tell can be seen), eye life, breath, the target model's rules and a voice delivery line. Write the acting prose from it, then atlas_lint the prose. Paid: $0.10 per call via x402 (USDC on Base), or prepaid credits with an API key (`Authorization: Bearer <key>`): 20 for $1.00 with atlas_buy_pack, or by card at https://creatinginai.com/agents#credits.
```

### `atlas_lint`

- 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
Check an acting paragraph or voice direction before spending credits: emotion labels, mugging, looks into the lens, quoted speech on hosts that block it, a tell bigger than the state allows, and the target's character cap. ok is true when there are no errors; each finding carries its fix. Free.
```

### `atlas_targets`

- 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
The target models the atlas knows, with each prompt field's character cap and what the model needs. Pass a target id to atlas_kit, atlas_draft and atlas_lint. Free.
```

## Only reads (2)

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

### `atlas_search`

- The name "atlas_search" says "search": a word for reading.
- Tag private-data: The description's first sentence says "note": it reads notes. The input names a table (input.table), and the tool reads: it reads databases.

Description, as the server wrote it:

```untrusted-server-text
Full-text search across behaviour cues, FACS action units, expressions, display strategies, emotions, situations, modifiers, model notes and targets. Search by emotion or situation; what comes back is behaviour. Free.
```

### `atlas_show`

- The name "atlas_show" says "show": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
One atlas record by id (or an emotion by name), with the records that use it. Free.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `performance-atlas`:

```json
{
  "permissions": {
    "allow": [
      "mcp__performance-atlas__atlas_search",
      "mcp__performance-atlas__atlas_show"
    ],
    "ask": [
      "mcp__performance-atlas__atlas_kit",
      "mcp__performance-atlas__atlas_draft",
      "mcp__performance-atlas__atlas_lint",
      "mcp__performance-atlas__atlas_targets",
      "mcp__performance-atlas__atlas_journey",
      "mcp__performance-atlas__atlas_buy_pack"
    ],
    "deny": []
  }
}
```

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

- `mcp__performance-atlas__atlas_search`: private-data
- `mcp__performance-atlas__atlas_buy_pack`: untrusted-input
