AI agents call get_memory_stats to retrieve information from Cognio without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves statistical information about memories (e.g., count, storage usage, date ranges) rather than reading individual memory contents. It is read-only with no side effects. The blast radius of misuse is minimal—an AI agent obtaining memory statistics poses no risk of data loss, modification, or unauthorized access to sensitive memory contents themselves.
From the tool's definition Tool name 'get_memory_stats' combined with description 'Get statistics about stored memories' indicates a query operation that retrieves aggregate data without modification.
Attacks that exploit this kind of access
Get statistics about stored memories. It is categorised as a Read tool in the Cognio MCP Server, which means it retrieves data without modifying state.
Register the Cognio MCP server in PolicyLayer and add a rule for get_memory_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 Cognio. Nothing to install.
get_memory_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_memory_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_memory_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_memory_stats is provided by the Cognio MCP server (0xrelogic/cognio). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
get_memory_stats is one line of Cognio's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
