AI agents call classical_query to retrieve information from MCP-RAGAnything without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The name 'classical_query' and its position among read-oriented sibling tools (list_*, read_*, query_*) indicate this retrieves or searches data from the RAG knowledge base without modifying, deleting, or executing arbitrary operations. Query operations are typically read-only in RAG systems.
From the tool's definition Tool name 'classical_query' suggests a query operation on the knowledge base, consistent with sibling tools like 'query_knowledge_base' and 'query_knowledge_base_multimodal' which are read operations. The empty description reduces confidence slightly.
Documented attack patterns abuse exactly the kind of access classical_query gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP-RAGAnything, and nothing reaches the server without passing your rules. This is the rule we recommend for classical_query:
{
"version": "1",
"default": "deny",
"tools": {
"classical_query": {}
}
}classical_query is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

classical_query. It is categorised as a Read tool in the MCP-RAGAnything MCP Server, which means it retrieves data without modifying state.
Register the MCP-RAGAnything MCP server in PolicyLayer and add a rule for classical_query: 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-RAGAnything. Nothing to install.
classical_query 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 classical_query 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 classical_query. 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.
classical_query is provided by the MCP-RAGAnything MCP server (soludevtech/mcp-raganything). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP-RAGAnything, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
