AI agents call hyperbolic_semantic_search 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 retrieves or queries data based on semantic relationships in a hierarchical structure. It provides different search perspectives but does not create, modify, delete, execute code, or perform financial operations. The blast radius of misuse is minimal—an agent could retrieve unintended information, but the operation is read-only with no side effects.
From the tool's definition The tool performs 'semantic search' with various query modes (nearest, subtree, ancestors, siblings, cone search). The verb 'search' and the description's focus on information retrieval without modifying data indicate this is a query operation.
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 Ruflo MCP Server, which means it retrieves data without modifying state.
Register the Ruflo 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 Ruflo. 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 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_semantic_search 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.
