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. How we score → Why this is hard to score →
Endpoint Security46
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to connect, but we couldn't read the whole tool list to see what that exposes. View diagnostics → Unverified
- HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability0
- Transport check failed: the endpoint responded but didn't complete an MCP handshake over streamable-http. See how to fix → View diagnostics → Fail
Schema Quality & AI Usability0
- Schema not yet verified: we couldn't read the endpoint's schema, or could read only part of its tool list.Unverified
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage0
- Tool coverage not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.Unverified
Tool Safety0
- Tool safety not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.Unverified
Capabilities0

Unverified: 5 categories
Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
accessibility_audit ~215
Run a WCAG accessibility audit on a page using axe-core in a real browser, and report the violations with the elements responsible. Because it runs against a genuinely rendered page, colour-contrast and other rules that depend on layout and computed colour actually fire — these are silently skipped by audits that parse HTML without a layout engine. Use this to check a page meets WCAG before shipping.
| Name | Type | Req | Description |
|---|---|---|---|
| max_violations | number | – | Maximum violation types to report in detail. 1-50. Defaults to 20. |
| standard | string | – | Which ruleset to run. 'wcag2aa' is the usual legal benchmark but is a narrow filter — it excludes best-practice checks such as landmarks and heading order, so a page can return zero violations and st… |
| url | string | yes | The absolute URL to audit, including https:// |
No output schema declared.
No examples provided.
inspect_element ~204
Answer 'why isn't this element showing where I expect?' for a CSS selector on a live page. Returns the resolved box model, computed display/visibility/opacity/position/z-index, colours, whether the element is inside the viewport, and — crucially — whether another element is covering it. These are the values a browser computes after the full cascade and layout; they cannot be derived from reading HTML and CSS.
| Name | Type | Req | Description |
|---|---|---|---|
| height | number | – | Viewport height in pixels. 240-2000. Defaults to 800. |
| max_matches | number | – | How many matching elements to report. 1-10. Defaults to 3. |
| selector | string | yes | CSS selector for the element to inspect, for example '.buy-button' or '#header nav a' |
| url | string | yes | The absolute URL to load, including https:// |
| width | number | – | Viewport width in pixels. 320-2560. Defaults to 1280. |
No output schema declared.
No examples provided.
page_diagnostics ~169
Load a page in a real browser and report what went wrong: JavaScript console errors and warnings, network requests that failed, and the HTTP status of the page itself. Use this when a site looks broken, a deployment might have shipped a bug, or a page loads blank and you need to know why. An agent cannot see a browser's console any other way.
| Name | Type | Req | Description |
|---|---|---|---|
| height | number | – | Viewport height in pixels. 240-2000. Defaults to 800. |
| include_warnings | boolean | – | Include console warnings and info messages, not just errors. Defaults to false. |
| url | string | yes | The absolute URL to load, including https:// |
| width | number | – | Viewport width in pixels. 320-2560. Defaults to 1280. |
No output schema declared.
No examples provided.
rendered_html ~125
Fetch a page's HTML *after* JavaScript has executed. Use this when a plain HTTP fetch returns an empty shell or a loading spinner — single-page apps, sites that build their content client-side, or anything behind a framework. Returns the final DOM as HTML text.
| Name | Type | Req | Description |
|---|---|---|---|
| max_chars | number | – | Truncate the returned HTML to this many characters. Defaults to 100000. |
| url | string | yes | The absolute URL to load, including https:// |
| wait_for | string | – | Optional CSS selector to wait for before capturing, for pages that load content late. |
No output schema declared.
No examples provided.
screenshot_url ~157
Take a screenshot of a web page as it actually renders in a real browser, after JavaScript has run. Use this when you need to see a page rather than read it — checking a layout, confirming a site is up and looks right, or capturing what a user would actually see. Returns a PNG image.
| Name | Type | Req | Description |
|---|---|---|---|
| full_page | boolean | – | Capture the entire scrollable page rather than just the viewport. Defaults to false. |
| height | number | – | Viewport height in pixels. 240-2000. Defaults to 800. |
| url | string | yes | The absolute URL to capture, including https:// |
| width | number | – | Viewport width in pixels. 320-2560. Defaults to 1280. |
No output schema declared.
No examples provided.
url_to_pdf ~79
Render a web page to PDF exactly as a browser would print it. Use this to archive a page, produce a document from a rendered report, or capture something for a record. Returns a PDF file.
| Name | Type | Req | Description |
|---|---|---|---|
| landscape | boolean | – | Landscape orientation. Defaults to false. |
| url | string | yes | The absolute URL to render, including https:// |
No output schema declared.
No examples provided.
