@codetoimage/mcp-server
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."
