A tool to calculate the skewness (measure of asymmetry) of a collection
AI agents call skewness_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.
The skewness_calculator performs statistical analysis on provided data to produce a numerical result (asymmetry measure). This is a non-destructive read operation that computes and returns information. There are no side effects, data modifications, code execution, deletions, or financial transactions involved. The tool fits squarely within the Read category as a data analysis function.
From the tool's definition Tool description states it 'calculate[s] the skewness...of a collection' — a pure computational operation that retrieves a statistical measure from input data without modifying, executing external operations, deleting data, or moving money.
Attacks that exploit this kind of access
A tool to calculate the skewness (measure of asymmetry) of a collection. 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 skewness_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.
skewness_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 skewness_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 skewness_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.
skewness_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.
