A tool to calculate the geometric mean of a collection of positive numbers
AI agents call geometric_mean_calculator to retrieve information from JeffersonStats without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Geometric mean calculation is a deterministic read-only mathematical operation. It accepts input, computes a statistic, and returns the result. There is no data persistence, deletion, external system interaction, or irreversible effect. This is consistent with other statistical analysis tools in the server (descriptive_statistics_summary, correlation_calculator, etc.) which are all Read-category operations.
From the tool's definition The tool performs a statistical calculation ('calculate the geometric mean') on input data with no modification, deletion, or external side effects. It is purely computational and returns a result without altering state.
Attacks that exploit this kind of access
A tool to calculate the geometric mean of a collection of positive numbers. It is categorised as a Read tool in the JeffersonStats MCP Server, which means it retrieves data without modifying state.
Register the JeffersonStats MCP server in PolicyLayer and add a rule for geometric_mean_calculator: 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 JeffersonStats. Nothing to install.
geometric_mean_calculator 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 geometric_mean_calculator 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 geometric_mean_calculator. 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.
geometric_mean_calculator is provided by the JeffersonStats MCP server (sharabhshukla/jeffersonstatsmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
