Evaluate if data collection follows minimization principles
AI agents call privacy.assess_data_minimization 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 performs passive assessment and evaluation of existing data practices against privacy principles. It reads/queries information about data collection policies to determine compliance with minimization standards. There are no side effects, no code execution, no data modification or deletion, and no financial impact.
From the tool's definition Tool name indicates 'assess' (evaluation/analysis) and description states 'Evaluate if data collection follows minimization principles' — a policy compliance check that retrieves and reviews data collection practices without modifying, deleting, or executing…
Attacks that exploit this kind of access
Evaluate if data collection follows minimization principles. 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 privacy.assess_data_minimization: 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.
privacy.assess_data_minimization 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 privacy.assess_data_minimization 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 privacy.assess_data_minimization. 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.
privacy.assess_data_minimization 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.
