Simple search interface - just provide a query and let the system handle everything
AI agents call search_code_simple to retrieve information from RAGex without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and searches code patterns from a codebase without creating, modifying, or deleting any data. It is a straightforward information retrieval mechanism with no side effects. The blast radius if misused is minimal—worst case, an agent could search for sensitive code patterns, but cannot alter or access anything beyond what a normal code search would reveal.
From the tool's definition Tool name 'search_code_simple' and description 'Simple search interface - just provide a query and let the system handle everything' indicate a query/search operation with no modification capabilities.

Documented attack patterns abuse exactly the kind of access search_code_simple gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and RAGex, and nothing reaches the server without passing your rules. This is the rule we recommend for search_code_simple:
{
"version": "1",
"default": "deny",
"tools": {
"search_code_simple": {}
}
}search_code_simple is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Simple search interface - just provide a query and let the system handle everything. It is categorised as a Read tool in the RAGex MCP Server, which means it retrieves data without modifying state.
Register the RAGex MCP server in PolicyLayer and add a rule for search_code_simple: 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 RAGex. Nothing to install.
search_code_simple 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_code_simple 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_code_simple. 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_code_simple is provided by the RAGex MCP server (jbenshetler/mcp-ragex). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from RAGex, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
