A tool to calculate the Spearman rank correlation coefficient between two collections
AI agents call spearman_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 read-only statistical analysis tool. It takes input data and returns a computed correlation metric without modifying, deleting, or executing external operations. Even in an AI misuse scenario, the worst outcome would be incorrect statistical conclusions from the analysis, not data loss, code execution, or financial impact.
From the tool's definition Tool calculates and returns the Spearman rank correlation coefficient; performs only statistical computation with no side effects, data modification, or external operations.
Attacks that exploit this kind of access
A tool to calculate the Spearman rank 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 spearman_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.
spearman_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 spearman_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 spearman_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.
spearman_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.
