Find all nodes matching the specified pattern. Use for comprehensive analysis when you need all matches.\n\nExamples:\n• Audit all functions: find_all_pattern(. It is categorised as a Read tool in the Tree-Hugger-JS MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Tree-Hugger-JS MCP Server MCP server in PolicyLayer and add a rule for find_all_pattern: 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 Tree-Hugger-JS MCP Server. Nothing to install.
find_all_pattern 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 find_all_pattern 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 find_all_pattern. 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.
find_all_pattern is provided by the Tree-Hugger-JS MCP Server MCP server (qckfx/tree-hugger-js-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
