Searches for videos based on a query string. Returns a list of videos matching the search criteria, including titles, descriptions, and metadata. Use this when you need to find videos related to specific topics or keywords.
AI agents call searchVideos to retrieve information from Yt without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only search operation on YouTube's public video database. It retrieves and presents information without modifying, creating, deleting, or executing any operations. The search function is inherently a data retrieval mechanism with minimal risk of misuse even if called by an AI agent.
From the tool's definition Tool description states it 'Searches for videos' and 'Returns a list of videos matching the search criteria.' This is a query operation with no side effects—it retrieves data only.
Attacks that exploit this kind of access
Searches for videos based on a query string. Returns a list of videos matching the search criteria, including titles, descriptions, and metadata. Use this when you need to find videos related to specific topics or keywords. It is categorised as a Read tool in the Yt MCP Server, which means it retrieves data without modifying state.
Register the Yt MCP server in PolicyLayer and add a rule for searchVideos: 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 Yt. Nothing to install.
searchVideos is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the searchVideos 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 searchVideos. 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.
searchVideos is provided by the Yt MCP server (yt-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
