计算阶乘
AI agents call factorial to retrieve information from Math Calculation MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The factorial function performs a read-only mathematical computation. It retrieves a calculated result based on input without creating, modifying, deleting data, executing external code, or affecting system state. Despite being part of a Math Calculation server with various capabilities, this specific tool is a simple arithmetic operation with no destructive, financial, or execution capabilities.
From the tool's definition Tool name: 'factorial', description: '计算阶乘' (Chinese: 'calculate factorial'). This is a pure mathematical computation function that takes a number and returns its factorial result with no side effects.
Attacks that exploit this kind of access
计算阶乘. It is categorised as a Read tool in the Math Calculation MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Math Calculation MCP Server MCP server in PolicyLayer and add a rule for factorial: 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 Math Calculation MCP Server. Nothing to install.
factorial 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 factorial 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 factorial. 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.
factorial is provided by the Math Calculation MCP Server MCP server (k-summer/math_mcps). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
