htmlcsstoimage.com
HTML/CSS to Image is a service that converts HTML, CSS, templates, and public URLs into rendered images and PDFs. It is used for generated social cards, screenshots, certificates, reports, and similar visual assets.
htmlcsstoimage.com exposes two developer integration surfaces: an authenticated REST API at `https://hcti.io` using Basic auth with API ID/API Key, and an OAuth-protected MCP server at `https://mcp.hcti.io` with Dynamic Client Registration for self-onboarding clients.
- HTML/CSS to Image MCP serverdetected
- HCTI REST APIdiscovered
Sign in to the HTML/CSS to Image dashboard and copy your API ID and API Key from your account details. The API docs say requests use HTTP Basic auth with the API ID as the username and the API Key as the password. Keep these server-side and do not expose them in client-side code.
Point your MCP client at the server URL and approve access in the browser. The server supports OAuth Dynamic Client Registration (RFC 7591), so the client registers itself automatically — no developer-portal app, client_id, or client_secret to create.
