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

| 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. | `mcp__seamgrin__apply_for_tailor_training` `mcp__seamgrin__join_customer_waitlist` `mcp__seamgrin__register_experienced_tailor_interest` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__seamgrin__get_alteration_options",
      "mcp__seamgrin__get_tailor_opportunities"
    ],
    "ask": [
      "mcp__seamgrin__join_customer_waitlist",
      "mcp__seamgrin__apply_for_tailor_training",
      "mcp__seamgrin__register_experienced_tailor_interest"
    ],
    "deny": []
  }
}
```

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

- `mcp__seamgrin__join_customer_waitlist`: untrusted-input
- `mcp__seamgrin__apply_for_tailor_training`: untrusted-input
- `mcp__seamgrin__register_experienced_tailor_interest`: untrusted-input

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 3 tools that change things (3 write). Whether a call also works without credentials was not tested: tools are never called.

https://seamgrin.com/mcp: tools/list returned 5 tools to an anonymous client, including join_customer_waitlist (write), apply_for_tailor_training (write), register_experienced_tailor_interest (write)
