Advanced search with ripgrep with more options
AI agents call advanced-search to retrieve information from Mcp Ripgrep 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 (searching file contents) with no side effects. It does not create, modify, delete, or execute code—it only returns matching results. The low severity reflects that misuse would be limited to unwanted information disclosure rather than system state changes.
From the tool's definition Tool is described as 'Advanced search with ripgrep with more options' and is a sibling to 'count-matches', 'list-file-types', and 'list-files'. Ripgrep is a text search utility that queries file contents without modifying them.

Register the Mcp Ripgrep MCP server in PolicyLayer and add a rule for advanced-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 Mcp Ripgrep. Nothing to install.
advanced-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 advanced-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 advanced-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.
advanced-search is provided by the Mcp Ripgrep MCP server (mcp-ripgrep). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
