AI agents call cache_stats to retrieve information from PM-MCP (Portfolio Management MCP Server) without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and returns information about cache metrics (size, item count, path). It performs no creation, modification, deletion, code execution, or financial operations. It is a passive information retrieval operation with no side effects on system state or data.
From the tool's definition Tool name is 'cache_stats' with description indicating it retrieves cache statistics: '캐시 통계 조회: 크기, 항목 수, 디렉토리 경로' (Cache statistics query: size, item count, directory path).

Register the PM-MCP (Portfolio Management MCP Server) MCP server in PolicyLayer and add a rule for 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 PM-MCP (Portfolio Management MCP Server). Nothing to install.
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 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 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.
cache_stats is provided by the PM-MCP (Portfolio Management MCP Server) MCP server (surplus96/pm-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
