sin · Math MCP Server for MacOS MCP: Risk & Policy

WHAT IT DOES

What sin does on Math MCP Server for MacOS

AI agents call sin to retrieve information from Math MCP Server for MacOS without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

WHY IT NEEDS A POLICY

Why sin needs a policy

This tool performs a pure mathematical computation (sine of a number). It reads an input value and returns a result without modifying any state, executing code, or causing any external effects.

From the tool's definition 'sin of a number' — computes the mathematical sine function, a pure calculation with no side effects
