Get statistics about the memory store — total count, total characters, and storage path.
AI agents call get_memory_stats to retrieve information from ContextKeep 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 read-only statistics (counts, character totals, storage path) about the memory store without any side effects. It performs a retrieval operation comparable to a 'get' or 'fetch' action. The low severity reflects that misuse would only expose metadata about stored memories, not the memories themselves or system operations.
From the tool's definition Tool name 'get_memory_stats' and description 'Get statistics about the memory store — total count, total characters, and storage path' indicate retrieval of aggregate metadata only, with no modification, deletion, or execution of code.
Documented attack patterns abuse exactly the kind of access get_memory_stats gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and ContextKeep, and nothing reaches the server without passing your rules. This is the rule we recommend for get_memory_stats:
{
"version": "1",
"default": "deny",
"tools": {
"get_memory_stats": {}
}
}get_memory_stats is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get statistics about the memory store — total count, total characters, and storage path. It is categorised as a Read tool in the ContextKeep MCP Server, which means it retrieves data without modifying state.
Register the ContextKeep 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 ContextKeep. 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 ContextKeep MCP server (mordang7/contextkeep). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from ContextKeep, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
