What measure_distance does on Uefn
AI agents call measure_distance to retrieve information from Uefn without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why measure_distance is rated Low
Measuring distance is a read-only operation that queries geometric or spatial data in the UEFN editor without creating, modifying, or deleting assets. It has minimal blast radius as an AI agent cannot cause harm by requesting distance measurements. Confidence is moderate (0.7) due to missing description; if the tool had side effects not apparent from the name, that would change the classification.
From the tool's definition Tool name 'measure_distance' suggests a query operation that retrieves or computes distance information without modifying state. No description provided, but the name implies data retrieval.
Attacks that exploit this kind of access
The rule that runs measure_distance safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Uefn, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For measure_distance, this is the rule to start with:
measure_distance is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Uefn, apply this rule, and every measure_distance call is checked against it from then on.
Questions about measure_distance
measure_distance is a read tool on the Uefn MCP server. It is categorised as a Read tool in the Uefn MCP Server, which means it retrieves data without modifying state.
Register the Uefn MCP server in PolicyLayer and add a rule for measure_distance: 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 Uefn. Nothing to install.
measure_distance 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 measure_distance 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 measure_distance. 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.
measure_distance is provided by the Uefn MCP server (quangdang46/uefn-verse-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
