AI agents call hooks_intelligence_pattern-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 performs a search operation over patterns using vector search algorithms (HNSW or brute-force). It retrieves or queries data without side effects, making it a Read operation. The severity is low because searching patterns poses minimal risk even if misused by an agent—the worst outcome would be information disclosure of existing pattern data.
From the tool's definition Tool name includes 'search' and description states 'Search patterns using REAL vector search'. The functionality is clearly retrieval-oriented with no modification, deletion, or execution capabilities mentioned.
Attacks that exploit this kind of access
Search patterns using REAL vector search (HNSW when available, brute-force fallback) Use when native Bash hooks (via Claude Code\. 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 hooks_intelligence_pattern-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.
hooks_intelligence_pattern-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 hooks_intelligence_pattern-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 hooks_intelligence_pattern-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.
hooks_intelligence_pattern-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.
hooks_intelligence_pattern-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.
