AI agents call square_root to retrieve information from TinyFn without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameters from the server's own tool schema.
This is a deterministic mathematical function that retrieves/computes a result from input parameters. It performs no I/O, state changes, or irreversible actions. It fits the 'Read' category as a query-like operation that returns computed data without side effects. The low severity reflects minimal blast radius—misuse would only produce incorrect calculations, not data loss or system compromise.
From the tool's definition Tool name 'square_root' and description 'Calculate the square root of a number' indicate a pure mathematical computation with no side effects, data modification, or external operations.

Calculate the square root of a number. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
square_root accepts 1 parameter: number. Required: number. The full parameter table on this page comes from the server's own tool schema.
Register the TinyFn 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 TinyFn. 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 TinyFn MCP server (https://api.tinyfn.io/mcp/all/). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
square_root is one line of TinyFn's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
