AI agents call get_stats to retrieve information from MCP RAG without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves statistical information about the RAG system state (likely document counts, memory metrics, storage usage, etc.). It performs no mutations, has no side effects, and cannot affect system integrity or security. Classification as Read is appropriate for a statistics-gathering operation.
From the tool's definition Tool name 'get_stats' and description 'Get statistics about the RAG system' indicate a query operation that retrieves system statistics without modifying data.
Attacks that exploit this kind of access
Get statistics about the RAG system. It is categorised as a Read tool in the MCP RAG MCP Server, which means it retrieves data without modifying state.
Register the MCP RAG MCP server in PolicyLayer and add a rule for get_stats: 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 RAG. Nothing to install.
get_stats 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 get_stats 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 get_stats. 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.
get_stats is provided by the MCP RAG MCP server (santis84/mcp-rag). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
