Install Plasmate in 30 Seconds

One command. Your AI gets a better browser.

Claude Code

claude mcp add plasmate -- npx plasmate-mcp

Done. Your Claude Code agent now has 13 web browsing tools.

Cursor

npx plasmate-mcp --install cursor

This auto-detects your Cursor config path and adds Plasmate. Restart Cursor.

Claude Desktop

npx plasmate-mcp --install claude-desktop

This adds the MCP config to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or the equivalent on Linux/Windows. Restart Claude Desktop.

Any MCP Client

If your client supports MCP stdio servers, add this to your config:

{
  "mcpServers": {
    "plasmate": {
      "command": "npx",
      "args": ["plasmate-mcp"]
    }
  }
}

Verify It Works

Ask your AI: "What are the top stories on Hacker News?"

It should use fetch_page and return structured content instead of raw HTML. If you see region names like navigation and main in the response, Plasmate is working.
