No check matched anything in these tool definitions.


## Changes things (5)

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

### `audit_landing_page`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Audit a landing page before sending paid ad traffic. Returns a 0-100 readiness score, a ready / fix_first / not_ready verdict, Meta, Google and TikTok tags with IDs, conversion paths (forms, click-to-call, WhatsApp, booking), trust and speed facts, and the top 5 fixes in priority order. Costs 0.05 USDC per completed call, paid automatically via x402 if your client supports it. Never charged if the call fails.
```

### `check_crawlability`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Check whether search engines and AI crawlers may read a page and how the site is mapped: robots.txt evaluated with Google's matching rules for Googlebot, Bingbot, GPTBot, OAI-SearchBot, ChatGPT-User, ClaudeBot, Google-Extended, PerplexityBot, CCBot, Applebot-Extended and others (with the rule that decided each), meta robots and X-Robots-Tag, canonical link, declared sitemaps with entry counts and freshness, and llms.txt, with a list of fixes. Costs 0.01 USDC per completed call, paid automatically via x402 if your client supports it. Never charged if the call fails.
```

### `check_structured_data`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Check a page's structured data: finds every schema.org item (JSON-LD, microdata, RDFa), reports JSON-LD that does not parse, checks each item against the required and recommended properties for common types (LocalBusiness, Organization, Product, Offer, Article, FAQPage, BreadcrumbList, Event, Review, JobPosting and more), flags bad dates, ratings and URLs, and reports Open Graph, Twitter card and canonical tags, with a list of fixes. Costs 0.01 USDC per completed call, paid automatically via x402 if your client supports it. Never charged if the call fails.
```

### `check_tracking`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Check which ad pixels and analytics a website runs: Meta Pixel, Google Ads and TikTok tags with their IDs, Google Analytics 4, tag managers (Google, Tealium, Adobe and others), conversion events, cookie consent tools and Google Consent Mode, the site platform (WordPress, Wix, Shopify, Squarespace...) and booking/chat tools. Costs 0.01 USDC per completed call, paid automatically via x402 if your client supports it. Never charged if the call fails.
```

### `full_site_report`

- 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.

- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Every Landfall check in one call, for less than the tools cost separately: the landing page audit, business contact details, tracking and pixel check, structured data check and crawlability check, from a single read of the page. Ideal for agency audits, lead qualification and prospect research. Costs 0.08 USDC per completed call, paid automatically via x402 if your client supports it. Never charged if the call fails.
```
