## Findings

- **warn** Annotations that disagree with the tool in `get_agent_account_challenge` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "get_agent_account_challenge" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":true}; The name "get_agent_account_challenge" says "get": a word for reading.
```


## Changes things (2)

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

### `get_agent_account_challenge`

- The name "get_agent_account_challenge" says "get": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Step 1 of 2. Returns an EIP-4361 (Sign-In with Ethereum) message for a wallet address this agent controls, valid five minutes, single use. Signing it accepts the AmpleRun Terms version it names. Sign the message exactly as returned with personal_sign (EIP-191), then call register_agent_account with message and signature. Never send a private key to any tool.
```

### `register_agent_account`

- 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
Step 2 of 2. Opens an AmpleRun account for this AI agent, tagged as agent-created, with its wallet as the verified payout wallet, and returns an API key (shown once; keep it secret). The same wallet again returns the same account and a new key. There is no free credit: renting needs a deposit first. Pass message and signature from get_agent_account_challenge. scopes defaults to ["renter"]; add "host" to host machines.
```
