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 Security83
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation is enforced on tool calls, but the challenge carries no valid RFC 9728 metadata, so a client cannot discover where to get a token. See how to fix → View diagnostics → Fail
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- 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 & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability63
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 920 tokens (~460/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the HTML to Image MCP server?
HTML to Image is a hosted endpoint at https://app.html2img.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

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 →
generate-image-from-html ~384
Render HTML and CSS into a PNG image, or into an A4 vector PDF with format "pdf". Provide complete, self-contained HTML and put styles in an inline <style> block. Remote image URLs load if they are real and publicly accessible; embed generated or local images as base64 data URIs rather than inventing URLs. Returns the rendered image plus a shareable CDN URL; PDF renders return the URL only. Consumes one credit per call.
| Name | Type | Req | Description |
|---|---|---|---|
| css | string | – | Optional additional CSS to inject into the page. |
| dpi | integer | – | Scale factor / device pixel ratio (1-4) for higher-resolution output. |

| fullpage | boolean | – | Capture the full scrollable page instead of just the viewport. |
| height | integer | – | Viewport height in pixels (1-5000). Defaults to 1080. |
| html | string | yes | The full HTML markup to render. Include CSS in an inline <style> block. Publicly accessible remote image URLs work; use base64 data URIs for images that are not hosted anywhere. |
| ms_delay | integer | – | Milliseconds to wait before capturing (1-5000), e.g. to let fonts or animations settle. |
| wait_for_selector | string | – | Wait until this CSS selector is present before capturing. |
