Set up HCTI in Cline

Capture a webpage or turn HTML/CSS into a PNG, WebP, or PDF with HTML/CSS to Image.

You’ll need: an HCTI account with image credits. Sign in through your browser when connecting—no API key to copy.

1. Open the MCP Servers panel in the Cline extension.
2. Choose Remote Servers and enter hcti as the server name.
3. Enter https://mcp.hcti.io as the URL and select Streamable HTTP.
4. Add the server and complete the HCTI authorization prompt in your browser.

To edit the configuration instead, open Configure → Configure MCP Servers in that panel and merge this entry under mcpServers:

{
  "mcpServers": {
    "hcti": {
      "type": "streamableHttp",
      "url": "https://mcp.hcti.io",
      "disabled": false,
      "autoApprove": []
    }
  }
}

Keep type explicit: Cline defaults to legacy SSE when it is omitted. Check that HCTI’s tools appear, then ask “Use HCTI to check my image usage and account limits” and approve the tool call when prompted. See Cline’s MCP guide.

Send this prompt after connecting:

Use HTML/CSS to Image to screenshot https://example.com as a PNG.
Set viewport_width to 1440 and device_scale to 1. Return the image URL.

Open the returned image URL to view your screenshot. Replace https://example.com with your own public URL.

Try a small card with explicit text, colors, and dimensions:

Use HCTI to render this HTML and CSS as a PNG at device_scale 1.
HTML: <div class="card">Hello from HCTI</div>
CSS: .card { width: 1200px; height: 630px; display: flex;
align-items: center; justify-content: center; background: #172554;
color: white; font: 64px sans-serif; }
Return the hosted image URL.

The result is a dark blue card with centered white text. Edit the text or CSS and render again to refine it.

Provide the data in your Cline conversation and ask:

Create an HTML/CSS table showing Starter: $9, Pro: $29, and Team: $99 per month. Use readable text and consistent column widths. Render it as a PNG with HCTI and return the image URL.

Review the rendered table at the returned URL. Ask Cline to adjust column widths or text sizes and render again if needed.

Available tools

These core tools work across MCP clients. Access depends on the permissions approved for your connection. Ask your assistant to use HCTI by name.

Account usage

Screenshots and rendering

Template management

See rendering parameters and the Template Editor for image options and reusable designs. The complete tools reference also covers proxies, storage destinations, Open Graph configurations, and required permissions.

For a permission-denied error, reconnect and approve the required access before retrying. Usage checks and maximum batch-size checks require usage:read.

Confirm the transport is Streamable HTTP, the server is enabled, and browser authorization completed. Restart the server from MCP settings if necessary. Cline may wait for tool-call approval before sending the rendering request.

HCTI fetches webpages from its hosted service. Use a publicly accessible URL; it cannot reach your computer’s localhost. For HTML/CSS rendering, supply the file contents and accessible assets rather than local file paths. Check your HCTI dashboard for available image credits.

See shared MCP troubleshooting for authentication and rendering errors, or choose another client.
