Calculates the square root of a non-negative number.
AI agents call calculate_sqrt to retrieve information from Calculator without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a stateless mathematical function that takes a numeric input and returns a computed result. It retrieves/computes a value without any side effects, data persistence changes, or external operations. It fits the 'Read' category definition as it produces output based on input without modifying any state.
From the tool's definition Tool name 'calculate_sqrt' and description 'Calculates the square root of a non-negative number' indicate a pure mathematical computation with no side effects, data modification, code execution, or external operations.

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