获取计算历史
AI agents call get_calculation_history 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.
This tool retrieves historical data without side effects. It queries past calculations that have already been performed, making it a read-only operation. No data is created, modified, deleted, or executed. The low severity reflects minimal blast radius—exposure of calculation history poses no direct operational risk.
From the tool's definition Tool name 'get_calculation_history' and description '获取计算历史' (Get calculation history) indicate retrieval of stored calculation records with no modification or deletion.
Attacks that exploit this kind of access
获取计算历史. 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 get_calculation_history: 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.
get_calculation_history 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 get_calculation_history 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 get_calculation_history. 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.
get_calculation_history 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.
