A tool to perform a one-sample t-test comparing a collection to a population mean
AI agents call t_test_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 t_test_calculator retrieves or computes statistical analysis results from provided data without side effects. It takes input (a collection and population mean), performs calculations, and returns results. This is a pure analytical operation typical of Read category tools.
From the tool's definition Tool performs a one-sample t-test, which is a statistical hypothesis test that analyzes and returns results without modifying any data. The description contains no language suggesting mutation, deletion, execution of external commands, or financial operations.
Attacks that exploit this kind of access
A tool to perform a one-sample t-test comparing a collection to a population mean. 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 t_test_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.
t_test_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 t_test_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 t_test_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.
t_test_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.
