Calculate the square root of a number.
AI agents call square_root to retrieve information from MCP Multi-Tool Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a pure mathematical computation (square root) with no side effects, no data modification, and no external interactions. It reads an input value and returns a computed result.

Calculate the square root of a number. It is categorised as a Read tool in the MCP Multi-Tool Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Multi-Tool Server MCP server in PolicyLayer and add a rule for square_root: 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 MCP Multi-Tool Server. Nothing to install.
square_root 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 square_root 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 square_root. 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.
square_root is provided by the MCP Multi-Tool Server MCP server (xiaoyuchenhot/mcp-example). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
