## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

## MCP tools (3)

### `scan_site` (~119 tokens)

Free AI readiness scan

Free. Checks a website's robots.txt rules for AI crawlers (GPTBot, OAI-SearchBot, ChatGPT-User, PerplexityBot, ClaudeBot, Google-Extended, CCBot), llms.txt, schema.org JSON-LD, title and meta description, content in raw HTML, and sitemap. Returns a 0 to 100 score and grade, plus a link to unlock the checks and prioritized fixes for $2.99.

Input parameters:

- `url` (string, required): Website URL, e.g. https://example.com

### `get_report` (~303 tokens)

Paid AI visibility report (x402)

Paid: the Lite report for 29 USDC (default) or the Full report for 49 USDC (tier "full"), via x402 (scheme exact). The same reports as the $29 Lite and $49 Full reports on the website. Returns the full report as JSON plus a private report link. Call once without `payment` to get the x402 payment requirements, then call again with the same arguments plus `payment` set to the base64 PAYMENT-SIGNATURE value. Payment is settled only if the report is delivered. If the call fails or times out after you pay, call get_report again with the same arguments and the same payment to get the result; you are never charged twice. If your x402 client caps payments, raise the cap to at least 49 USDC to buy the Full report.

Input parameters:

- `brand` (string): Business name (default: derived from the domain)
- `category` (string)
- `competitors` (array): Up to 5 competitor names
- `payment` (string): x402 v2 PAYMENT-SIGNATURE header value (base64 JSON payment payload)
- `prompts` (array): Your prompts are answered first. We add generated questions to fill the rest, up to 25.
- `tier` (string): "lite" (default, 29 USDC) or "full" (49 USDC)
- `url` (string, required): Website URL, e.g. https://example.com

### `get_scan_details` (~164 tokens)

Paid scan details (x402)

Paid: 2.99 USDC via x402 (scheme exact), the same $2.99 scan details as on the website. Runs the AI readiness scan for one website and returns every check, the score breakdown and the prioritized fixes as JSON. Call once without `payment` to get the x402 payment requirements, then again with `payment`. Payment is settled only if the scan completes. If the call fails or times out after you pay, call get_scan_details again with the same arguments and the same payment to get the result; you are never charged twice.

Input parameters:

- `payment` (string): x402 v2 PAYMENT-SIGNATURE header value (base64 JSON payment payload)
- `url` (string, required): Website URL, e.g. https://example.com
