## 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)

Scored 2026-09-28.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (check_page).
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 83/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 636 tokens (~106/item across 6 items; 6 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 10/100
  - Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (6)

### `check_page` (~117 tokens)

Choose this for broad website testing when the caller wants screenshots, responsive layout checks, accessibility findings, console/network errors, performance evidence, and a release diagnosis across phone portrait, phone landscape, and desktop. For explicit pass/fail assertions use verify_page instead. Costs $0.08 USDC via x402. Requires an x402-aware client to authorise payment; standard AI assistants cannot automatically sign x402.

Input parameters:

- `url` (string, required): Public HTTPS page URL. Private, loopback, credentialed, and non-HTTPS URLs are rejected.

### `verify_page` (~138 tokens)

Choose this only when the caller supplies explicit website assertions that need pass/fail results across three viewports. For broad exploratory browser QA use check_page instead. Assertion types: noHorizontalOverflow, noConsoleErrors, textVisible, titleIncludes, selectorExists, selectorVisible. Costs $0.10 USDC via x402. Requires an x402-aware client; standard AI assistants cannot automatically sign x402.

Input parameters:

- `assertions` (array, required): One to twenty explicit pass/fail assertions to evaluate across all three viewports.
- `url` (string, required): Public HTTPS page URL. Private, loopback, credentialed, and non-HTTPS URLs are rejected.

### `compare_page` (~133 tokens)

Choose this for visual regression testing after check_page has produced a completed, unexpired baseline. Compares screenshots and QA evidence, returning pixel-diff percentages, new or resolved accessibility issues, error deltas, performance evidence, and diagnosis. Costs $0.12 USDC via x402. Requires an x402-aware client; standard AI assistants cannot automatically sign x402.

Input parameters:

- `baselineJobId` (string, required): Completed, unexpired ViewportWitness check job to use as the visual baseline.
- `url` (string, required): Public HTTPS page URL. Private, loopback, credentialed, and non-HTTPS URLs are rejected.

### `extract_page` (~91 tokens)

Choose this when an agent needs the readable content of a public webpage as deterministic clean Markdown, without screenshots or browser execution. Costs $0.005 USDC via x402.

Input parameters:

- `maxOutputTokens` (integer): Optional approximate output budget from 500 to 12000 tokens.
- `url` (string, required): Public HTTPS page URL. Private, loopback, credentialed, and non-HTTPS URLs are rejected.

### `web_release_gate` (~94 tokens)

Choose this for a passive website release-security review of headers, cookie flags, mixed content, cross-origin script integrity, and server disclosure. It does not run browser QA, probe the site, execute code, or replace a security audit. Costs $0.05 USDC via x402.

Input parameters:

- `url` (string, required): Public HTTPS page URL. Private, loopback, credentialed, and non-HTTPS URLs are rejected.

### `get_report` (~63 tokens)

Retrieve the status or completed QA report for a previously submitted job. Free and read-only. Poll until status is "complete", "failed", or "retryable". No payment required.

Input parameters:

- `jobId` (string, required): ViewportWitness job UUID returned by a paid tool.
