A tool to perform the Wilcoxon signed-rank test for two related samples
AI agents call wilcoxon_test 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 wilcoxon_test tool is a specialized statistical analysis function that takes two related samples as input and computes a standard statistical test result. This is a Read operation because it retrieves/computes results from data without side effects—no data is created, modified, deleted, or destroyed, and no external systems are invoked.
From the tool's definition Tool performs the Wilcoxon signed-rank test, a statistical hypothesis test that analyzes and returns results from provided data samples.
Attacks that exploit this kind of access
A tool to perform the Wilcoxon signed-rank test for two related samples. 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 wilcoxon_test: 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.
wilcoxon_test 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 wilcoxon_test 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 wilcoxon_test. 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.
wilcoxon_test 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.
