## 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__cgbb__get_trust_file` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__cgbb__apply_for_membership` `mcp__cgbb__check_domain_verification` `mcp__cgbb__get_trust_file` `mcp__cgbb__verify_brand` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

No check matched anything in these tool definitions.


## Changes things (4)

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

### `about_cgbb`

- 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
What CGBB is, what the free CGBB Member trust.json contains, and how an AI agent can apply for a brand.
```

### `apply_for_membership`

- The name "apply_for_membership" says "apply": a word for a change.
- 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
Apply for free CGBB membership on behalf of a brand. Returns an application_id, a domain-verification token and next steps. A real person at the brand (contact_email) must confirm by email; the CGBB Secretariat then reviews it.
```

### `check_domain_verification`

- 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
After publishing the token (DNS TXT record or /.well-known/cgbb-verification.txt), check it. Returns the updated application status.
```

### `verify_brand`

- 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.
- 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
Check the live CGBB record for a domain, and whether a genuine trust.json is published on that website.
```

## Only reads (2)

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

### `get_application_status`

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

Description, as the server wrote it:

```untrusted-server-text
Status and next steps for an application.
```

### `get_trust_file`

- The name "get_trust_file" says "get": a word for reading.
- Tag private-data: The name "get_trust_file" says "get" and "file": it reads files.
- Tag untrusted-input: The description's first sentence says "get" and "http": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Get the signed CGBB Member trust.json for an approved domain, ready to publish at https://<domain>/.well-known/trust.json.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__cgbb__get_application_status",
      "mcp__cgbb__get_trust_file"
    ],
    "ask": [
      "mcp__cgbb__about_cgbb",
      "mcp__cgbb__apply_for_membership",
      "mcp__cgbb__check_domain_verification",
      "mcp__cgbb__verify_brand"
    ],
    "deny": []
  }
}
```

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

- `mcp__cgbb__apply_for_membership`: untrusted-input
- `mcp__cgbb__check_domain_verification`: untrusted-input
- `mcp__cgbb__verify_brand`: untrusted-input
- `mcp__cgbb__get_trust_file`: private-data, untrusted-input
