Steel MCP Server

https://github.com/user-attachments/assets/25848033-40ea-4fa4-96f9-83b6153a0212

A Model Context Protocol (MCP) server that enables LLMs like Claude to navigate the web through Puppeteer-based tools and Steel. Based on the Web Voyager framework, it provides tools for all the standard web actions click clicking/scrolling/typing/etc and taking screenshots.

Ask Claude to help you with tasks like:

"Search for a recipe and save the ingredients list"
"Track a package delivery status"
"Find and compare prices for a specific product"
"Fill out an online job application"

🚀 Quick Start

Below is a streamlined guide to run Steel Voyager inside Claude Desktop. You only need to adjust the environment options to switch between Steel Cloud and a local/self-hosted instance.

Prerequisites

Latest versions of Git and Node.js installed
Claude Desktop installed
(Optional) Steel Docker image running locally, if you plan to self-host
(Optional) If running Steel Cloud, bring your API key. Get one here.

A) Quick Start (Steel Cloud)

Clone and build the project:

git clone https://github.com/steel-dev/steel-mcp-server.git
cd steel-mcp-server
npm install
npm run build

Configure Claude Desktop (~/Library/Application Support/Claude/claude_desktop_config.json) by adding a server entry:

{
  "mcpServers": {
    "steel-puppeteer": {
      "command": "node",
      "args": ["path/to/steel-voyager/dist/index.js"],
      "env": {
        "STEEL_LOCAL": "false",
        "STEEL_API_KEY": "YOUR_STEEL_API_KEY_HERE",
        "GLOBAL_WAIT_SECONDS": "1"
      }
    }
  }
}

Replace "YOUR_STEEL_API_KEY_HERE" with your valid Steel API key.
Make sure "STEEL_LOCAL" is set to "false" for cloud mode.

Start Claude Desktop. It will automatically launch this MCP server in Cloud mode.
(Optional) You can view or manage active Steel Browser sessions in your dashboard.

B) Quick Start (Local / Self-Hosted Steel)

Ensure your local or self-hosted Steel service is running (e.g., using the open-source Steel Docker image).

Clone and build the project (same as above if not done yet):

git clone https://github.com/steel-dev/steel-mcp-server.git
cd steel-mcp-server
npm install
npm run build

Configure Claude Desktop (~/Library/Application Support/Claude/claude_desktop_config.json) for local mode:

{
  "mcpServers": {
    "steel-puppeteer": {
      "command": "node",
      "args": ["path/to/steel-voyager/dist/index.js"],
      "env": {
        "STEEL_LOCAL": "true",
        "STEEL_BASE_URL": "http://localhost:3000",
        "GLOBAL_WAIT_SECONDS": "1"
      }
    }
  }
}

"STEEL_LOCAL" must be "true".
If self hosting on a cloud server, configure "STEEL_BASE_URL" to point to your local/self-hosted Steel URL.

Start Claude Desktop, which will connect to your locally running Steel and launch Steel Voyager in local mode.
(Optional) To view sessions locally, you can visit your self-hosted dashboard (localhost:5173) or logs specific to your Steel runtime environment.

That’s it! Once Claude Desktop starts, it will orchestrate the MCP server behind the scenes and let you interact with the web automation capabilities through Steel Voyager.
