计算自然对数
AI agents call ln 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 ln function retrieves a computed mathematical result based on input arguments. It performs a read-only calculation without modifying state, deleting data, executing arbitrary code, or triggering financial transactions. This is a safe, deterministic mathematical operation.
From the tool's definition Tool name 'ln' and description indicate it computes the natural logarithm (ln = natural log). This is a pure mathematical computation with no side effects, data modification, code execution, or external operations.
Attacks that exploit this kind of access
计算自然对数. 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 ln: 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.
ln 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 ln 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 ln. 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.
ln 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.
