Cline MCP Integration

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. Connect a remote server in Cline

Open the MCP Servers panel in the Cline extension.
Choose Remote Servers and enter hcti as the server name.
Enter https://mcp.hcti.io as the URL and select Streamable HTTP.
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.

2. Take a screenshot

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.

3. Render HTML/CSS

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.

How to export a table as an image

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

HTML/CSS to Image (HCTI) exposes the same MCP tools in every supported client. Ask your assistant to use HCTI by name when you want it to render HTML/CSS or capture a website.

Account usage

Tool	What it does
check_usage	Check images used, the account’s image allowance, the next reset date, and whether overages are enabled. Does not render an image.

Screenshots and rendering

Tool	What it does
create_image	Render HTML and CSS as PNG, JPG, WebP, or PDF. Accepts rendering options such as `device_scale`, `viewport_width`, `viewport_height`, and `ms_delay`.
create_url_image	Capture a public webpage or a specific element using a CSS selector. Supports viewport settings and cookie banner blocking.
create_templated_image	Render a saved template using its `template_id` and a `template_values` object.
create_batch_images	Render multiple variations in one request, with shared `default_options` and per-image `variations`.
get_max_batch_size	Check the authorized account’s current batch limit before preparing a batch.

Template management

Tool	What it does
create_template	Save HTML and CSS as a reusable template with variables.
update_template	Update an existing template by ID.
list_templates	Find templates in the connected HCTI account.
list_template_versions	Inspect the version history of a template.

See the rendering parameters for available options and the Template Editor guide for designing reusable templates.

Troubleshooting

Missing tools or connection errors

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.

Rendering errors

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.
