WHAT IT DOES

What cache_stats does on Enhanced Knowledge Graph Memory Server

AI agents call cache_stats to retrieve information from Enhanced Knowledge Graph Memory Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why cache_stats is rated Low

Even though cache_stats only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

RECOMMENDED RULE

The rule that runs cache_stats safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Enhanced Knowledge Graph Memory Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For cache_stats, this is the rule to start with:

cache_stats Allowed

cache_stats is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "cache_stats": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Enhanced Knowledge Graph Memory Server, apply this rule, and every cache_stats call is checked against it from then on.

FAQ

Questions about cache_stats

What does the cache_stats tool do? +

v12.5.0 \u2014 Per-tier snapshot of the global search caches (basic / ranked / boolean / fuzzy) showing hits / misses / size / hitRate. Process-local \u2014 every fresh server process starts at zero. It is categorised as a Read tool in the Enhanced Knowledge Graph Memory Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on cache_stats? +

Register the Enhanced Knowledge Graph Memory 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 Enhanced Knowledge Graph Memory Server. Nothing to install.

What risk level is cache_stats? +

cache_stats is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit cache_stats? +

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.

How do I block cache_stats completely? +

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.

What MCP server provides cache_stats? +

cache_stats is provided by the Enhanced Knowledge Graph Memory Server MCP server (danielsimonjr/memory-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
