Search memories by semantic similarity. Returns the most relevant
AI agents call widemem_search 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.
This tool retrieves data from the memory layer based on semantic matching. While it is a Read operation and does not modify state, the severity is elevated to medium because (1) the memory system may contain sensitive agent reasoning, user preferences, or private context that an adversary could exfiltrate via repeated searches, and (2) in an agent context, unrestricted search access could allow inference attacks or…
From the tool's definition Tool name 'widemem_search' and description 'Search memories by semantic similarity. Returns the most relevant' indicate a query/retrieval operation with no modification or deletion of data.
Documented attack patterns abuse exactly the kind of access widemem_search 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_search:
{
"version": "1",
"default": "deny",
"tools": {
"widemem_search": {}
}
}widemem_search is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search memories by semantic similarity. Returns the most relevant. 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_search: 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_search 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_search 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_search. 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_search 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.
