divide · Weather MCP Server MCP: Risk & Policy

WHAT IT DOES

What divide does on Weather MCP Server

AI agents invoke divide to trigger actions in Weather MCP 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 a division calculation (mathematical operation). It has no data storage side effects, no destructive potential, and no financial implications. It executes a computation and returns a result, making 'Execute' the most appropriate category, though it's a very benign operation.

From the tool's definition Tool name is 'divide' and description is '除法计算器' (division calculator in Chinese). It performs arithmetic computation.

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.

除法计算器. It is categorised as a Execute tool in the Weather MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on divide? +

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? +
