WHAT IT DOES

What divide_numbers does on ContextForge MCP Gateway

AI agents call divide_numbers to retrieve information from ContextForge MCP Gateway without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why divide_numbers is rated Low

This tool performs arithmetic division on two numbers and returns the result. It is a pure computation with no side effects, data modification, or external operations. The 'error handling in output' phrase indicates it gracefully handles division by zero in the response rather than through exceptions. Equivalent to a read/query operation.
