A tool to calculate the trimmed mean of a collection
AI agents call trimmed_mean_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 trimmed mean calculator performs a read-only statistical computation on input data. It retrieves/analyzes data to produce a result (the trimmed mean value) with no side effects, data modification, code execution, or external operations. This is characteristic of the Read category: query and analysis tools that have no impact beyond returning computed results.
From the tool's definition Tool description states it 'calculate[s] the trimmed mean of a collection' - a purely computational operation that computes and returns a statistical metric without modifying data, executing code, or triggering external operations.
Attacks that exploit this kind of access
A tool to calculate the trimmed mean 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 trimmed_mean_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.
trimmed_mean_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 trimmed_mean_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 trimmed_mean_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.
trimmed_mean_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.
