## 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__brainfile__get_starter_file` `mcp__brainfile__list_pack_contents` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__brainfile__list_pack_contents` |
| 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.


## Only reads (3)

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

### `get_freshness_sample`

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

Description, as the server wrote it:

```untrusted-server-text
Get the real Brainfile freshness feed entry that ships in the pack — the weekly 'living system' update (the same improvements we run on our own six live businesses + what changed in Claude Code, with how to apply each to your brain/). This is the retention mechanic; a paid license keeps the newest feed flowing.
```

### `get_starter_file`

- The name "get_starter_file" says "get": a word for reading.
- Tag private-data: The name "get_starter_file" says "get" and "file": it reads files. The description's first sentence says "get" and "file": it reads files.

Description, as the server wrote it:

```untrusted-server-text
Get the REAL Brainfile free-tier starter files — the on-ramp that turns generic Claude into a project that remembers you. Full text, no account needed. Files: INTERVIEW-ME.md (first-session interview that personalizes your CLAUDE.md), START-HERE.md (orientation + first prompt), CLAUDE.starter.md (starter operating-system playbook). Omit 'name' to get all three.
```

### `list_pack_contents`

- The name "list_pack_contents" says "list": a word for reading.
- Tag private-data: The description's first sentence says "list" and "file": it reads files.
- Tag untrusted-input: The description's first sentence says "list" and "conversation": it reads messages, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
List the full Brainfile pack manifest: the v1 pattern files (Autopilot protocol, never-empty backlog, never-forgets ledger, interview onboarding, end-of-run brief template, conversation-history pattern, freshness feed — each with a one-line description; starter files fetchable right here over MCP, the rest via the free no-card trial pull), plus the paid role packs (15) — listed but locked, with the unlock URL. Use this to see everything Brainfile ships before starting a trial.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__brainfile__get_starter_file",
      "mcp__brainfile__list_pack_contents",
      "mcp__brainfile__get_freshness_sample"
    ],
    "ask": [],
    "deny": []
  }
}
```

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

- `mcp__brainfile__get_starter_file`: private-data
- `mcp__brainfile__list_pack_contents`: private-data, untrusted-input
