Get statistics about the current knowledge base
AI agents call get_knowledge_base_stats to retrieve information from Chalee MCP RAG without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns statistical information about the knowledge base (e.g., document count, storage metrics, embedding stats). It is a read-only operation with no side effects, making it a Read category tool. Severity is low because knowledge base statistics are not sensitive operational data and misuse poses minimal risk. High confidence due to clear naming and functional transparency.
From the tool's definition Tool name 'get_knowledge_base_stats' and description 'Get statistics about the current knowledge base' indicate a retrieval operation that returns metadata about the knowledge base state without modifying, executing, or deleting anything.
Attacks that exploit this kind of access
Get statistics about the current knowledge base. It is categorised as a Read tool in the Chalee MCP RAG MCP Server, which means it retrieves data without modifying state.
Register the Chalee MCP RAG MCP server in PolicyLayer and add a rule for get_knowledge_base_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 Chalee MCP RAG. Nothing to install.
get_knowledge_base_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_knowledge_base_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_knowledge_base_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_knowledge_base_stats is provided by the Chalee MCP RAG MCP server (prettyking/chalee-mcp-rag). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
