AI agents call browser_video_show_actions as a supporting operation in Playwright workflows.
The tool name suggests it shows or displays actions related to browser video, which would be a read/display operation. However, with an empty description and given the context of a Playwright server (which runs browser automation), there is uncertainty. The 'show' prefix suggests a read-like display operation with no side effects, but confidence is low due to lack of description.
From the tool's definition Tool name 'browser_video_show_actions' and empty description provide minimal information. Name suggests displaying/showing video actions rather than modifying state.

PolicyLayer is an MCP gateway — it sits between your AI agents and Playwright, and nothing reaches the server without passing your rules. This is the rule we recommend for browser_video_show_actions:
{
"version": "1",
"default": "deny",
"tools": {
"browser_video_show_actions": {
"limits": [
{
"counter": "browser_video_show_actions_rate",
"window": "minute",
"max": 60,
"scope": "grant"
}
]
}
}
}browser_video_show_actions gets a rate cap, and everything else on the server is denied unless you say otherwise.
