AI agents call list_knowledge_base_documents to retrieve information from RAD Security without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a simple enumeration or listing operation to retrieve document metadata from a knowledge base. It has no capability to modify, delete, or execute operations.
From the tool's definition Tool name 'list_knowledge_base_documents' and description 'List documents in your organization' indicate querying/retrieval of existing data with no modification or side effects.
Documented attack patterns abuse exactly the kind of access list_knowledge_base_documents gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and RAD Security, and nothing reaches the server without passing your rules. This is the rule we recommend for list_knowledge_base_documents:
{
"version": "1",
"default": "deny",
"tools": {
"list_knowledge_base_documents": {}
}
}list_knowledge_base_documents is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
List documents in your organization. It is categorised as a Read tool in the RAD Security MCP Server, which means it retrieves data without modifying state.
Register the RAD Security MCP server in PolicyLayer and add a rule for list_knowledge_base_documents: 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 RAD Security. Nothing to install.
list_knowledge_base_documents 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 list_knowledge_base_documents 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 list_knowledge_base_documents. 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.
list_knowledge_base_documents is provided by the RAD Security MCP server (rad-security/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from RAD Security, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
