獲取查詢緩存統計信息
AI agents call get_cache_stats to retrieve information from Memory MCP Server 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 cache statistics—a read-only operation with no side effects. It retrieves information about cache state rather than modifying, deleting, or executing code. The low severity reflects minimal blast radius if misused by an agent, as the tool cannot alter system state or trigger unintended operations.
From the tool's definition Tool name 'get_cache_stats' and description '獲取查詢緩存統計信息' (Get query cache statistics) indicate retrieval of statistical metadata about cache performance. No modification, deletion, or execution of external operations occurs.
Attacks that exploit this kind of access
獲取查詢緩存統計信息. It is categorised as a Read tool in the Memory MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Memory MCP Server MCP server in PolicyLayer and add a rule for get_cache_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 Memory MCP Server. Nothing to install.
get_cache_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_cache_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_cache_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_cache_stats is provided by the Memory MCP Server MCP server (win10ogod/memory-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
