A tool to calculate the moving average of a time series
AI agents call moving_average_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.
Moving average calculation is a deterministic mathematical operation that reads time series data and returns computed results. It does not create, modify, delete, or execute any state-changing operations. This is clearly a Read category tool with minimal risk; misuse would yield incorrect statistics but no harmful consequences.
From the tool's definition Tool performs 'calculate the moving average of a time series' — a computational query operation that produces derived statistical metrics without modifying input data or triggering external side effects.
Attacks that exploit this kind of access
A tool to calculate the moving average of a time series. 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 moving_average_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.
moving_average_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 moving_average_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 moving_average_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.
moving_average_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.
