Compare results across multiple evaluation runs with statistical analysis
AI agents call workflow.compare_evaluations to retrieve information from ContextForge MCP Gateway without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and analyzes existing evaluation data to produce comparative results. It performs no side effects—no data is created, modified, deleted, or executed. The statistical analysis is performed on already-stored evaluation results, making this a read-only operation with minimal security risk.
From the tool's definition Tool name and description indicate data comparison and statistical analysis: 'Compare results across multiple evaluation runs with statistical analysis'. No modification, deletion, or code execution is described.
Attacks that exploit this kind of access
Compare results across multiple evaluation runs with statistical analysis. It is categorised as a Read tool in the ContextForge MCP Gateway MCP Server, which means it retrieves data without modifying state.
Register the ContextForge MCP Gateway MCP server in PolicyLayer and add a rule for workflow.compare_evaluations: 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 ContextForge MCP Gateway. Nothing to install.
workflow.compare_evaluations 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 workflow.compare_evaluations 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 workflow.compare_evaluations. 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.
workflow.compare_evaluations is provided by the ContextForge MCP Gateway MCP server (jrmatherly/mcp-context-forge). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
