Graph statistics — node count, edge counts by type, top entities.
AI agents call memcp_graph_stats to retrieve information from Memcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and reports aggregate statistics (counts, rankings) from a knowledge graph. It is a read-only operation that queries existing data without side effects. No data is created, modified, deleted, or executed. The blast radius if misused is minimal—an agent could only gain visibility into statistics about stored memory structure, which poses no destructive risk.
From the tool's definition Tool name 'memcp_graph_stats' and description 'Graph statistics — node count, edge counts by type, top entities' indicate retrieval and querying of statistical metadata about an internal graph structure.
Documented attack patterns abuse exactly the kind of access memcp_graph_stats gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Memcp, and nothing reaches the server without passing your rules. This is the rule we recommend for memcp_graph_stats:
{
"version": "1",
"default": "deny",
"tools": {
"memcp_graph_stats": {}
}
}memcp_graph_stats is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Graph statistics — node count, edge counts by type, top entities. It is categorised as a Read tool in the Memcp MCP Server, which means it retrieves data without modifying state.
Register the Me MCP server in PolicyLayer and add a rule for memcp_graph_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 Memcp. Nothing to install.
memcp_graph_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 memcp_graph_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 memcp_graph_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.
memcp_graph_stats is provided by the Me MCP server (maydali28/memcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Memcp, 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.
