## Changes things (4)

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

### `claim_trial`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
claim the one-time free first Solo month for your first server (the POST /trial/claim operation; Bearer token required)
```

### `conformance_check`

- The description's first verb is "run": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
run one full client x IdP-shape conformance matrix (the POST /check operation; x402 $0.01 per check unless your account has an active Solo subscription/trial, metered exactly as REST)
```

### `run_history`

- The name "run_history" says "run": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
list only your own account's past matrix runs (the GET /history operation; Bearer token required)
```

### `subscribe_solo`

- The name "subscribe_solo" says "subscribe": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
activate/extend a Solo month, $9 via x402 X-PAYMENT header (the POST /subscribe operation; Bearer token required)
```

## Only reads (1)

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