## Findings

No check matched anything in these tool definitions.


## Changes things (4)

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

### `buy_credits`

- 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
How to buy Neuronto credits, the one prepaid balance for every paid Neuronto call (searches past the free allowance, multi-step discovery, the change feed, publisher monitoring, gateway fees): the packs, what each thing costs, and the x402 URL to pay.
```

### `integration_snippet`

- 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
Working code to start charging for a route through this facilitator, in the language and framework you name, plus a live URL to test the client against. Copy it as it is; the only thing to change is the wallet.
```

### `monetize_api`

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

Description, as the server wrote it:

```untrusted-server-text
Put an existing HTTPS API behind x402 without changing its code: returns a paid URL that answers 402 with your price, forwards paid calls to your API, and settles each payment straight to your wallet. 1,000 paid calls a month free, then 1% from prepaid credits. Pass your key, or omit it and a new one is returned.
```

### `settlement_price`

- 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
What a settlement costs through this facilitator, per network, with the basis it was computed from. Free while the service is in launch pricing.
```

## Only reads (2)

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

### `facilitator_status`

- The name "facilitator_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
What this x402 facilitator can settle right now: the live networks and schemes, whether the echo merchant is serving, the state of address screening, observed availability and settlement counts. Call this before advertising a price, because a network that cannot settle is withdrawn here first.
```

### `find_paid_resource`

- The name "find_paid_resource" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search the catalogue of resources that have been paid for through this facilitator: the URL, the terms, the method, and the input and output shapes where the merchant published them. A resource is listed only after a real settlement and a probe, so nothing here is a claim by its owner.
```
