Calculates the base-10 logarithm of a positive number.
AI agents call calculate_log10 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 is a pure computational function that retrieves/computes a mathematical result from an input parameter. It matches the 'Read' category as it produces no side effects—no data is written to any system, no commands are executed, and no external operations are triggered. The severity is low because misuse of a logarithm calculator poses minimal risk to systems or data integrity.
From the tool's definition Tool 'calculate_log10' performs a mathematical calculation (base-10 logarithm) on a number provided as input. No data is created, modified, deleted, or persisted. No external operations or side effects occur.
Attacks that exploit this kind of access
Calculates the base-10 logarithm 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_log10: 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_log10 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_log10 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_log10. 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_log10 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.
