Multiplies two numbers and returns the result.
AI agents call multiply to retrieve information from FastMCP Beginner MCP Servers without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a stateless arithmetic calculation. It takes two numbers as arguments, computes their product, and returns the result. There are no data modifications, deletions, code execution, financial transactions, or external side effects. It is functionally equivalent to a simple read/query operation in that it retrieves a computed result without altering any system state.
From the tool's definition Tool name is 'multiply' and description states it 'Multiplies two numbers and returns the result' — a pure mathematical operation that reads inputs and returns a computed output with no side effects, modifications, or external operations.
Attacks that exploit this kind of access
Multiplies two numbers and returns the result. It is categorised as a Read tool in the FastMCP Beginner MCP Servers MCP Server, which means it retrieves data without modifying state.
Register the FastMCP Beginner MCP Servers 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 FastMCP Beginner MCP Servers. Nothing to install.
multiply is a Read tool with low risk. Read-only tools are generally safe to allow by default.
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.
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.
multiply is provided by the FastMCP Beginner MCP Servers MCP server (papasmurf79/mcpserverproject). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
