## Findings

No check matched anything in these tool definitions.


## Changes things (5)

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

### `batch`

- 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
Check up to 25 sellers and 25 websites in one call (cheapest for many checks).
```

### `changes`

- 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 changed since a day — keep a local copy in sync.
```

### `check_seller`

- 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
Our latest independent check of one paid seller, by its address (any spelling) or id: answering, price, buyers, and its paid answers checked against an independent record (with proof).
```

### `check_website`

- 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
Can AI agents use this shopping or travel website? Plain-agent access, each AI agent at the door, robots rules, llms.txt, history.
```

### `sellers_on_domain`

- 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
Every paid seller we check on one host.
```

## Only reads (4)

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

### `find_route`

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

Description, as the server wrote it:

```untrusted-server-text
Where to go for a job, before you spend tokens on trial and error: the best tested free official source with its exact call and how much it returns (and a fallback). Ask in plain words, e.g. 'UK company directors', 'Apple revenue', 'EU gas storage'. detail=full adds the paid sellers we rate and other sources.
```

### `list_categories`

- The name "list_categories" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Every category of paid service agents buy, with sellers, buyers and how we check it; names in your language with lang.
```

### `list_websites`

- The name "list_websites" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Rated websites, filtered by market (e.g. 'United States', 'Japan'), plain-agent outcome (open, blocked, timeout) or price honesty (does the price agents read match what people see).
```

### `search_sellers`

- The name "search_sellers" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find paid x402 data services AI agents can buy, inside one category, ranked. Use before paying any seller.
