What wavexis_cast_stop does on Wavexis
AI agents invoke wavexis_cast_stop to trigger actions in 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.
Why wavexis_cast_stop is rated High
This tool executes a command that controls a browser or device capability (cast mirroring), affecting an active external session. While not destructive (the cast can be restarted) or write-oriented (not modifying data), it triggers a state-changing operation on an active system process. Misuse could disrupt user workflows or media sessions.
From the tool's definition Tool name 'wavexis_cast_stop' and description 'Stop active cast mirroring' indicate the tool triggers an external operation (stopping screen mirroring/casting) whose effects depend on the current state of casting sessions.
Attacks that exploit this kind of access
The rule that runs wavexis_cast_stop safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Wavexis, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For wavexis_cast_stop, this is the rule to start with:
wavexis_cast_stop 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Wavexis, apply this rule, and every wavexis_cast_stop call is checked against it from then on.
Questions about wavexis_cast_stop
Stop active cast mirroring. It is categorised as a Execute tool in the Wavexis MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Wavexis MCP server in PolicyLayer and add a rule for wavexis_cast_stop: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Wavexis. Nothing to install.
wavexis_cast_stop is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the wavexis_cast_stop rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for wavexis_cast_stop. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
