Summary
Wraps the codetoimage.app REST API so your agent can render HTML/CSS into PNG, JPG, or WebP without leaving the chat. Two tools: render_html_to_image returns the image inline for instant preview, while render_html_to_url gives you a 24-hour hosted link you can drop into og:image tags, Slack messages, or anywhere else that needs a public URL. You control dimensions up to 2048×2048, output format, transparency, and background color through the schema. Runs via npx with just an API key, no local dependencies. Useful when you're iterating on Open Graph cards, generating chart PNGs from data visualizations, or building dynamic badge images that need to live outside the conversation.

Official Model Context Protocol server for codetoimage.app – render HTML/CSS to PNG/JPG/WebP directly from Claude Desktop, Claude Code, Cursor, or any MCP-compatible client.
What you get
Two tools, no setup beyond an API key:
render_html_to_image– returns the image inline so your agent (or you, in chat) can see it immediately. Best for "show me the rendered card", OG preview iteration, chart generation, badge mockups.render_html_to_url– returns a temporary hosted URL (24h TTL). Best when the image needs to live somewhere external – Instagram Graph API, OpenGraph meta tags, Slack unfurls, docs/posts embeds.
Install
You don't need to install anything globally – MCP clients can run it via npx. Get an API key at codetoimage.app/dashboard/keys, then add the config below.
Claude Desktop
Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):
{
"mcpServers": {
"codetoimage": {
"command": "npx",
"args": ["-y", "@codetoimage/mcp-server"],
"env": {
"CODETOIMAGE_API_KEY": "cti_live_..."
}
}
}
}
Restart Claude Desktop. The two tools appear in the tool picker.
Claude Code
claude mcp add codetoimage -s user -- npx -y @codetoimage/mcp-server
Then set the env var in your shell profile (or pass -e CODETOIMAGE_API_KEY=cti_live_… in the claude mcp add call).
Cursor
Edit ~/.cursor/mcp.json:
{
"mcpServers": {
"codetoimage": {
"command": "npx",
"args": ["-y", "@codetoimage/mcp-server"],
"env": {
"CODETOIMAGE_API_KEY": "cti_live_..."
}
}
}
}
Usage from an agent
The tools are self-documenting – your agent will pick the right one based on intent. Example prompts that just work:
"Render this card as a PNG:
<div style='padding:40px;background:#6366f1;color:white;border-radius:16px'>Hello</div>at 800×400."
"Generate an Open Graph image for the blog post 'Why agents need pixel-perfect rendering' and give me a URL I can paste into the og:image meta tag."
"Take this CSS card and render it as a transparent PNG so I can use it on a dark background."
"Render my saved template 3f2a91d0-... with title 'Launch day' as an Instagram story."
