AI agents call hyperbolic_hierarchy_compare to retrieve information from Ruflo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a mathematical/structural comparison operation (computing similarity metrics between hierarchies). There is no indication of data modification, deletion, external command execution, or financial transactions. The operation is read-only analysis with no side effects beyond returning computed results.
From the tool's definition Tool name 'hyperbolic_hierarchy_compare' and description 'Compare hierarchies... Computes structural and semantic similarity' indicate a query/analysis operation.
Attacks that exploit this kind of access
Compare hierarchies using hyperbolic alignment. Computes structural and semantic similarity with node-level alignments. It is categorised as a Read tool in the Ruflo MCP Server, which means it retrieves data without modifying state.
Register the Ruflo MCP server in PolicyLayer and add a rule for hyperbolic_hierarchy_compare: 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 Ruflo. Nothing to install.
hyperbolic_hierarchy_compare 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 hyperbolic_hierarchy_compare 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 hyperbolic_hierarchy_compare. 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.
hyperbolic_hierarchy_compare is provided by the Ruflo MCP server (ruvnet/ruflo). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
hyperbolic_hierarchy_compare is one line of Ruflo's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
