Get statistics about the knowledge base
AI agents call get_stats to retrieve information from Self-Improving Memory MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves statistics from an internal knowledge base, which is a read-only operation. No data is created, modified, deleted, or executed. The most severe risk is information disclosure about the knowledge base structure, which is low impact for an AI agent. The confidence is high because the description clearly indicates a retrieval operation with no side effects.
From the tool's definition Tool name is 'get_stats' and description states 'Get statistics about the knowledge base' — a query operation that retrieves aggregate data without modifying or executing anything.
Attacks that exploit this kind of access
Get statistics about the knowledge base. It is categorised as a Read tool in the Self-Improving Memory MCP MCP Server, which means it retrieves data without modifying state.
Register the Self-Improving Memory 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 Self-Improving Memory MCP. 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 Self-Improving Memory MCP server (superpitt/self-improving-memory-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
