Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

@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."

Tool schemas

render_html_to_image

| Field | Type | Required | Notes | |---|---|---|---| | html | string | ✓ | Full HTML (typically with <body>) | | css | string | – | Optional CSS injected as <style> | | width | integer 1-2048 | – | Default 800 | | height | integer 1-2048 | – | Default 600 | | format | png | jpeg | webp | – | Default png | | quality | integer 1-100 | – | JPEG/WebP only | | transparent | boolean | – | PNG/WebP, paid plans | | background | string | – | e.g. #ffffff or rgb(…) |

Same input schema as render_html_to_image. Returns a text block with:

  • url — temporary hosted image URL
  • format — final output format
  • expires_at — ISO timestamp (24h from render)
  • credits_remaining — your plan's quota state

Configuration

| Variable | Default | Purpose | |---|---|---| | CODETOIMAGE_API_KEY | – | Required. Get one at codetoimage.app/dashboard/keys | | CODETOIMAGE_API_URL | https://api.codetoimage.app | API base URL (override for dev/proxy) |
