A tool to calculate the interquartile range (IQR) of a collection
AI agents call iqr_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 IQR calculator performs a mathematical operation on supplied data to compute a descriptive statistic (interquartile range). This is a read-only analytical function that retrieves no external data and produces no side effects, state changes, or irreversible actions. It fits the 'Read' category as a straightforward statistical query tool.
From the tool's definition Tool name 'iqr_calculator' and description 'calculate the interquartile range (IQR) of a collection' indicate a pure statistical computation function that reads input data and returns a calculated metric without modifying, deleting, or executing external…
Attacks that exploit this kind of access
A tool to calculate the interquartile range (IQR) 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 iqr_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.
iqr_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 iqr_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 iqr_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.
iqr_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.
