AI agents call widemem_count to retrieve information from Widemem Ai without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs a read-only count operation on stored memories. It retrieves statistical information (cardinality) without modifying, deleting, or executing any operations. The filtering capability is a standard query parameter that does not alter data. This is a typical Read category tool with minimal security risk—no blast radius from misuse beyond potential information disclosure about memory count.
From the tool's definition Tool name 'widemem_count' and description 'Count stored memories, optionally filtered by user' indicate a query/retrieval operation that returns an aggregate count with no mutation, deletion, or side effects.
Documented attack patterns abuse exactly the kind of access widemem_count gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Widemem Ai, and nothing reaches the server without passing your rules. This is the rule we recommend for widemem_count:
{
"version": "1",
"default": "deny",
"tools": {
"widemem_count": {}
}
}widemem_count is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Count stored memories, optionally filtered by user. It is categorised as a Read tool in the Widemem Ai MCP Server, which means it retrieves data without modifying state.
Register the Widemem Ai MCP server in PolicyLayer and add a rule for widemem_count: 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 Widemem Ai. Nothing to install.
widemem_count 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 widemem_count 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 widemem_count. 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.
widemem_count is provided by the Widemem Ai MCP server (remete618/widemem-ai). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
