`region`	string	—	Browser region (default us-west-2)

Parameters from the server's own tool schema.

RECOMMENDED RULE

The rule that runs infra.browser.create_session safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Apibase, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For infra.browser.create_session, this is the rule to start with:

infra.browser.create_session Rate-limited

infra.browser.create_session stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
