Search files for patterns using ripgrep (rg)
AI agents call 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 queries and retrieves file contents matching specified patterns. It has no side effects—it does not create, modify, delete, or execute code. It is a typical read operation that poses minimal security risk unless the search results themselves contain sensitive information that could be exposed.
From the tool's definition Tool name 'search' with description 'Search files for patterns using ripgrep (rg)' indicates read-only file searching functionality. Ripgrep is a text search utility that retrieves matching content without modifying files.
Attacks that exploit this kind of access
Search files for patterns using ripgrep (rg). It is categorised as a Read tool in the Mcp Ripgrep MCP Server, which means it retrieves data without modifying state.
Register the Mcp Ripgrep MCP server in PolicyLayer and add a rule for 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.
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 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 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.
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.
