AI agents call analyze_difficulty to retrieve information from Loenn without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs read-only analysis and estimation of game difficulty based on map data characteristics. It retrieves and computes metrics from the map structure without creating, modifying, deleting, or executing any external operations. The analysis is informational and has no side effects on the map or game state.
From the tool's definition Tool description states it "estimate[s]" difficulty metrics by analyzing existing map properties like "hazard density, nav aids, and tile coverage" — purely observational analysis with no modification or execution of external operations.
Attacks that exploit this kind of access
Estimate room or map difficulty from hazard density, nav aids, and tile coverage. It is categorised as a Read tool in the Loenn MCP Server, which means it retrieves data without modifying state.
Register the Loenn MCP server in PolicyLayer and add a rule for analyze_difficulty: 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 Loenn. Nothing to install.
analyze_difficulty 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 analyze_difficulty 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 analyze_difficulty. 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.
analyze_difficulty is provided by the Loenn MCP server (magedeline/loenn-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
