Why use Composio?

Apart from a managed and hosted MCP server, you will get:

  • Programmatic tool calling allows LLMs to write its code in a remote workbench to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling.
  • Handling Large tool responses out of LLM context to minimize context rot.
  • Dynamic just-in-time access to 20,000 tools across 1000+ other Apps for cross-app workflows. It loads the tools you need, so LLMs aren't overwhelmed by tools you don't need.

How to install HTML/CSS to Image with OpenClaw

Using Composio API Key and Setup Prompt

Copy the setup prompt from the OpenClaw dashboard
  • Run it in your OpenClaw chat interface.
  • Authenticate HTML/CSS to Image from the dashboard
  • Go back to your OpenClaw interface and start asking questions.

Using OpenClaw/Composio Plugin

1. Install OpenClaw Composio plugin

bash
openclaw plugins install @composio/openclaw-plugin

2. Copy the API Key from dashboard.composio.dev

3. Setup OpenClaw Config

bash
openclaw config set plugins.entries.composio.config.consumerKey "ck_your_key_here"

4. Restart OpenClaw

bash
openclaw gateway restart

5. Go to your chat interface and start asking questions.

6. When prompted, authenticate the app and you're all set.

How It Works

The plugin connects to Composio's MCP server at https://connect.composio.dev/mcp and registers all available tools directly into the OpenClaw agent. Tools are called by name — no extra search or execute steps needed.

If a tool returns an auth error, the agent will prompt you to connect that toolkit at dashboard.composio.dev.

What is the HTML/CSS to Image MCP server, and what's possible with it?

The HTML/CSS to Image MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your HTML/CSS to Image account. It provides structured and secure access to your image generation, reusable templates, generated files, and usage data, so your agent can create images, render templates, transform files, manage templates, and monitor usage on your behalf.

  • HTML and webpage rendering: Have your agent turn HTML and CSS or public web pages into hosted images, including protected pages that require request headers.
  • Batch image creation: Direct your agent to generate up to 25 images at once from HTML, CSS, or web pages using shared or image-specific settings.
  • Reusable template management: Let the agent create Handlebars templates, list your existing templates, and update them with new HTML, CSS, or render settings.
  • Image retrieval and transformation: Instruct your agent to download generated images, convert their format, resize them, crop them, or permanently delete files you no longer need.
  • Account usage tracking: Have your agent review recent hourly, daily, monthly, and billing-period image usage for your connected account.

FAQ

Frequently asked questions

With a standalone HTML/CSS to Image MCP server, the agents and LLMs can only access a fixed set of HTML/CSS to Image tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from HTML/CSS to Image and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. OpenClaw fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right HTML/CSS to Image tools.

Yes, absolutely. You can configure which HTML/CSS to Image scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your HTML/CSS to Image data and credentials are handled as safely as possible.
