divide · Calculator MCP Server MCP: Risk & Policy

WHAT IT DOES

What divide does on Calculator MCP Server

AI agents invoke divide to trigger actions in Calculator 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

The tool description is empty, so classification relies on the name and context. Given the sibling tools are all basic arithmetic operations, 'divide' almost certainly performs division. This is an Execute-category tool (runs a mathematical computation), though the blast radius is very low since it only computes a result with no side effects. Confidence is reduced due to the empty description.

From the tool's definition Tool name 'divide' on a calculator MCP server with sibling tools: add, subtract, multiply, square_root, percentage, power, modulo, absolute — all basic arithmetic operations.

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.

FAQ

Questions about divide

What does the divide tool do? +

divide. It is categorised as a Execute tool in the Calculator 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? +

Register the Calculator MCP Server MCP server in PolicyLayer and add a rule for divide: 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 Calculator MCP Server. Nothing to install.

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? +

Set action: deny in the PolicyLayer policy for divide. 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.

What MCP server provides divide? +

divide is provided by the Calculator MCP Server MCP server (sathiya-moorthi/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
