List all available documents in the DOCS_PATH directory. Always use this tool first to check if desired documents already exist before adding new ones.
AI agents call list_documents to retrieve information from MCP Docs RAG Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool queries and returns information about existing documents without creating, modifying, deleting, or executing anything. It is purely informational, consistent with the Read category (retrieve or query data; no side effects). Severity is low because listing documents poses minimal security risk even if misused by an AI agent.
From the tool's definition Tool name is 'list_documents' and description states it 'List[s] all available documents in the DOCS_PATH directory'. This is a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access list_documents gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Docs RAG Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_documents:
{
"version": "1",
"default": "deny",
"tools": {
"list_documents": {}
}
}list_documents is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all available documents in the DOCS_PATH directory. Always use this tool first to check if desired documents already exist before adding new ones. It is categorised as a Read tool in the MCP Docs RAG Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Docs RAG Server MCP server in PolicyLayer and add a rule for list_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 MCP Docs RAG Server. Nothing to install.
list_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_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_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_documents is provided by the MCP Docs RAG Server MCP server (kazuph/mcp-docs-rag). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP Docs RAG Server, 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.
