divide · MCP Quickstart Weather Server MCP: Risk & Policy

WHAT IT DOES

What divide does on MCP Quickstart Weather Server

AI agents invoke divide to trigger actions in MCP Quickstart Weather Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why divide needs a policy

This tool performs arithmetic division of two numbers. The description is minimal but the operation is a mathematical computation with no data storage, deletion, or financial implications. Classified as Execute since it performs a computation/operation rather than purely reading stored data. Severity is low as the blast radius of a division operation is negligible, though division by zero could cause an error.

From the tool's definition Tool name 'divide' with description 'Divide a by b.'

Verdict

divide Rate-limited

divide stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

What risk level is divide? +

divide is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit divide? +

Yes. Add a rate_limit block to the divide 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.

How do I block divide completely? +
