"""
HTTP Example for mcp_use.

This example demonstrates how to use the mcp_use library with MCPClient
to connect to an MCP server running on a specific HTTP port.

Before running this example, you need to start the Playwright MCP server
in another terminal with:

    npx @playwright/mcp@latest --port 8931

This will start the server on port 8931. Resulting in the config you find below.
Of course you can run this with any server you want at any URL.

Special thanks to https://github.com/microsoft/playwright-mcp for the server.
