## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `latest_crypto_headlines`

- 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
Free: latest 5 crypto headlines (title, source, url, published_at, topics), optional topics filter. Full feed with summaries, tickers, since cursor: GET /v1/news via x402 ($0.0008 USDC on Base).
```

## Only reads (1)

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

### `count_new_crypto_news`

- The name "count_new_crypto_news" says "count": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Free: how many new items arrived since a cursor (next_since) for given topics/tickers, so an agent only pays for /v1/news when there is something new.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `crypto-news`:

    ],
    "ask": [
      "mcp__crypto-news__latest_crypto_headlines"
