Semantic search with hierarchical awareness. Supports nearest, subtree, ancestors, siblings, and cone search modes.
AI agents call hyperbolic_semantic_search 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.
This tool retrieves or queries data from a semantic search index using various hierarchical traversal patterns. It has no side effects—it does not create, modify, delete, or execute external operations. The supported modes (nearest, subtree, ancestors, siblings, cone) are all selection/filtering operations typical of information retrieval. Classification as Read is appropriate with high confidence.
From the tool's definition Tool is named 'hyperbolic_semantic_search' and described as performing 'Semantic search with hierarchical awareness' supporting query modes like 'nearest, subtree, ancestors, siblings, and cone search'.
Attacks that exploit this kind of access
Semantic search with hierarchical awareness. Supports nearest, subtree, ancestors, siblings, and cone search modes. 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_semantic_search: 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_semantic_search 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_semantic_search 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_semantic_search. 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_semantic_search 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.
