Search YouTube for channels. Cost: 100 units.
AI agents call search_channels to retrieve information from SergeyKrin9/mcp Servers without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a search operation on YouTube to retrieve channel information. Search operations are fundamentally read-only with no side effects—they query existing data without creating, modifying, deleting, or executing anything. The cost unit system is incidental to the operation type. No irreversible actions, code execution, financial obligations, or data modification occur.

Search YouTube for channels. Cost: 100 units. It is categorised as a Read tool in the SergeyKrin9/mcp Servers MCP Server, which means it retrieves data without modifying state.
Register the SergeyKrin9/mcp Servers MCP server in PolicyLayer and add a rule for search_channels: 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 SergeyKrin9/mcp Servers. Nothing to install.
search_channels 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 search_channels 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 search_channels. 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.
search_channels is provided by the SergeyKrin9/mcp Servers MCP server (sergeykrin9/mcp-servers). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
