AI agents call memory_stats_detail to retrieve information from Tages without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves and aggregates statistical metadata about stored memories. It has no side effects, cannot modify data, and poses minimal security risk. The worst-case misuse would be information disclosure of memory statistics, which in a coding agent context is low impact.
From the tool's definition Tool description explicitly states it provides 'Detailed memory statistics — counts by type and status, average confidence, top 5 agents, and total count'.
Attacks that exploit this kind of access
Detailed memory statistics — counts by type and status, average confidence, top 5 agents, and total count. It is categorised as a Read tool in the Tages MCP Server, which means it retrieves data without modifying state.
Register the Tages MCP server in PolicyLayer and add a rule for memory_stats_detail: 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 Tages. Nothing to install.
memory_stats_detail 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 memory_stats_detail 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 memory_stats_detail. 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.
memory_stats_detail is provided by the Tages MCP server (ryantlee25-droid/tages). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
