Calculates the natural logarithm (base e) of a positive number.
AI agents call calculate_natural_log to retrieve information from Calculator without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only mathematical calculation. It takes a number as input and returns a computed result without creating, modifying, deleting, or executing any operations. It has no capability to affect system state, data storage, or external resources. Misuse by an AI agent would be limited to potentially incorrect calculations, which poses minimal security risk.
From the tool's definition Tool description states it 'Calculates the natural logarithm (base e) of a positive number' - a pure mathematical computation with no side effects, data modification, or external operations.
Attacks that exploit this kind of access
Calculates the natural logarithm (base e) of a positive number. It is categorised as a Read tool in the Calculator MCP Server, which means it retrieves data without modifying state.
Register the Calculator MCP server in PolicyLayer and add a rule for calculate_natural_log: 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 Calculator. Nothing to install.
calculate_natural_log 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 calculate_natural_log 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 calculate_natural_log. 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.
calculate_natural_log is provided by the Calculator MCP server (mvavassori/calculator-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
