multiply · Example MCP Server MCP: Risk & Policy

WHAT IT DOES

What multiply does on Example MCP Server

AI agents invoke multiply to trigger actions in Example 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 multiply needs a policy

This tool performs arithmetic multiplication. While it has no side effects and is read-like in nature, it executes a computation rather than retrieving stored data. Blast radius is extremely low as it only returns a numeric result with no external effects. Confidence is slightly reduced because the description is minimal and doesn't clarify if there are any side effects.

Verdict

multiply Rate-limited

multiply 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Example MCP Server, so you can run agents against it safely.

FAQ

Questions about multiply

What does the multiply tool do? +

Multiply two numbers. It is categorised as a Execute tool in the Example 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 multiply? +

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

What risk level is multiply? +

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

Can I rate-limit multiply? +

Yes. Add a rate_limit block to the multiply 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 multiply completely? +

Set action: deny in the PolicyLayer policy for multiply. 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 multiply? +

multiply is provided by the Example MCP Server MCP server (joseph19820124/joseph_mcp_server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
