## Findings

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

```untrusted-server-text
The server marks "payment_guard" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":false,"openWorldHint":true}; The name "payment_guard" says "payment": a word that usually means money moves, which cannot be taken back.
```


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `payment_guard`

- The name "payment_guard" says "payment": a word that usually means money moves, which cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Use for agent payment safety: validate a live x402 challenge, price, Base network, USDC asset, recipient, funding, gas reserve, and destination immediately before signing.
```

## Changes things (6)

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

### `batch_check_urls`

- 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
Check up to ten public URLs in one paid call with isolated results for partial failures.
```

### `check_url`

- 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
Check one public URL's reachability, HTTP status, latency, redirects, and content type before using it.
```

### `merchant_audit`

- 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
Audit listings, semantic rank, competitor prices, payment reliability, buyer reach, and observed Base USDC activity. Repeated runs with the same wallet and queries return privacy-safe score history and change alerts.
```

### `recommend_tool`

- 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
Use this free tool before paying. Describe the decision you need and receive the best Anyway Possible tool, exact price, required inputs, alternatives, and next step. This tool never triggers payment or calls an external service.
```

### `treasury_preflight`

- 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
Check Base wallet readiness, ETH and USDC funding, gas, chain intent, destination type, and common payment hazards before signing.
```

### `verify_web_evidence`

- 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
Verify one public URL and return timestamped status, redirects, metadata, content hash, and a receipt.
```

## Only reads (2)

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

### `base_balance`

- The description's first verb is "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read native ETH and Circle USDC balances plus current block height for a Base wallet.
```

### `merchant_snapshot`

- The name "merchant_snapshot" says "snapshot": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Score an x402 merchant's discovery, reliability, buyer signals, and observed Base USDC activity, then identify the largest revenue issue.
```
