A tool to calculate the Pearson correlation coefficient between two collections
AI agents call correlation_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.
This is a statistical analysis tool that performs a mathematical calculation on provided data. It retrieves/computes a correlation metric without creating, modifying, deleting data, executing external commands, or incurring financial obligations. The operation is deterministic and non-destructive, making it a Read category tool with low severity risk.
From the tool's definition The tool 'calculate[s] the Pearson correlation coefficient between two collections' - a pure statistical computation that reads input data and returns a calculated metric with no side effects, data modification, or external operations.
Attacks that exploit this kind of access
A tool to calculate the Pearson correlation coefficient between two collections. 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 correlation_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.
correlation_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 correlation_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 correlation_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.
correlation_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.
