AI agents call query_multimodal to retrieve information from RAG-Anything MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Despite the empty description, the tool name and server context strongly suggest this performs read-only queries on multimodal data within the knowledge graph. The server explicitly supports 'multiple query modes' for information retrieval. No evidence of data modification, deletion, execution of arbitrary code, or financial impact.
From the tool's definition Tool name 'query_multimodal' and sibling tools include 'query_knowledge_graph' and multiple query modes (naive, local, global, hybrid) described in server capabilities.
Documented attack patterns abuse exactly the kind of access query_multimodal gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and RAG-Anything MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for query_multimodal:
{
"version": "1",
"default": "deny",
"tools": {
"query_multimodal": {}
}
}query_multimodal is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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