@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."
