Browser Use MCP

Agent Loop in Practice

Connect Browser Use to your agent in four steps. DAuth encrypts credentials client-side; the MCP server never sees raw secrets.

step_1.py

from dedalus_mcp.auth import Connection, SecretKeys
 
browser_use_mcp = Connection(
    name="browser-use-mcp",
    secrets=SecretKeys(api_key="BROWSER_USE_API_KEY"),
    base_url="https://api.browser-use.com",
    auth_header_name="X-Browser-Use-API-Key",
    auth_header_format="{api_key}",
)
