WHAT IT DOES

What wavexis_cast_start does on Pypi:wavexis

AI agents invoke wavexis_cast_start to trigger actions in Pypi:wavexis. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why wavexis_cast_start is rated High

This tool executes a browser command that initiates a cast session, which is an external operation whose effects (establishing a media stream connection, mirroring screen content to another device) depend on runtime conditions and cannot be simply queried.

From the tool's definition Tool name 'wavexis_cast_start' and description 'Start tab mirroring to a cast sink' indicate an action that triggers an external operation (initiating cast/screen mirroring protocol).

RECOMMENDED RULE

The rule that runs wavexis_cast_start safely

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

wavexis_cast_start Rate-limited

wavexis_cast_start 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.
