计算一个数字的幂
AI agents call power to retrieve information from Simple Calculator MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a mathematical power/exponentiation calculation. It only reads input values and returns a computed result, with no data modification, execution of commands, or external interactions. It is part of a simple calculator MCP server alongside other arithmetic operations (add, subtract, multiply, divide), all of which are pure computational reads.
From the tool's definition Tool name 'power' and description '计算一个数字的幂' (calculate the power of a number) indicate a pure mathematical computation with no side effects.
Attacks that exploit this kind of access
计算一个数字的幂. It is categorised as a Read tool in the Simple Calculator MCP MCP Server, which means it retrieves data without modifying state.
Register the Simple Calculator MCP server in PolicyLayer and add a rule for power: 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 Simple Calculator MCP. Nothing to install.
power 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 power 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 power. 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.
power is provided by the Simple Calculator MCP server (sanlanglove/mcp-calculator). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
