MCP server

The MCP server gives any MCP client a private cloud browser it pays for with its own wallet. It is one file, it runs on Node 20 or later, and it has no dependencies.

curl -O https://www.usebrowserai.xyz/sdk/browserai-mcp.mjs

Configure your client

Add it to Claude Desktop, Cursor, or any client that reads an mcpServers block. BROWSERAI_KEY is the private key of the wallet that pays; set BROWSERAI_PAY to x402 to pay per session instead of from a balance.
