Compare hierarchies using hyperbolic alignment. Computes structural and semantic similarity with node-level alignments.
AI agents call hyperbolic_hierarchy_compare to retrieve information from Claude Flow without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs similarity computation and comparison operations on hierarchies, which are analytical/query-type activities. There is no indication it modifies data (Write), executes external code/commands (Execute), deletes data (Destructive), or moves money (Financial). The verb 'compute' and 'compare' align with Read category operations that retrieve and analyze information without side effects.
From the tool's definition Tool description states it "Compare[s] hierarchies" and "Computes structural and semantic similarity" — these are data analysis and comparison operations with no modifications, deletions, or external execution indicated.
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 Claude Flow MCP Server, which means it retrieves data without modifying state.
Register the Claude Flow 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 Claude Flow. 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 Claude Flow MCP server (claude-flow). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
