## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__symbola__get_pack` `mcp__symbola__read_pack_file` |
| 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. | none |

## Findings

No check matched anything in these tool definitions.


## Only reads (5)

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

### `get_build_steps`

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

Description, as the server wrote it:

```untrusted-server-text
How to build a pack: the steps a coding agent with a shell follows (install the symbola CLI, pull the pack, build each component and run its checks), and a one-line request the user can paste into Claude Code or another coding agent.
```

### `get_pack`

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

Description, as the server wrote it:

```untrusted-server-text
Overview of one pack: what it builds, its version, how many decisions it holds, its components, its page and download link, and the files it holds.
```

### `read_decisions`

- The name "read_decisions" says "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The decisions a pack makes: each one a rule a builder could get wrong, with its status (decided, default or open). Narrow them to one component or to decisions mentioning some words.
```

### `read_pack_file`

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

Description, as the server wrote it:

```untrusted-server-text
Read one file of a pack, e.g. PRODUCT.md (the whole product), AGENTS.md (how to build it), BRIEF.md, obligations.toml, an assumption, or a component's symbolon.toml or examples.jsonl. "pack.md" is the whole pack as one Markdown page.
```

### `search_packs`

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

Description, as the server wrote it:

```untrusted-server-text
Search the Symbola registry for packs: software a coding agent can build from its decisions. Matches words against each pack's name, summary, id and category. With no query, lists every pack.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__symbola__search_packs",
      "mcp__symbola__get_pack",
      "mcp__symbola__read_decisions",
      "mcp__symbola__read_pack_file",
      "mcp__symbola__get_build_steps"
    ],
    "ask": [],
    "deny": []
  }
}
```

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

- `mcp__symbola__get_pack`: private-data
- `mcp__symbola__read_pack_file`: private-data
