AI agents call get_recent_memories to retrieve information from Memory-Plus without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries previously recorded memories without modifying, deleting, or executing external operations. It fits the Read category as a data retrieval function. Severity is low because accessing local memory records poses minimal risk; the blast radius of misuse is confined to information disclosure within an already-local system.
From the tool's definition Tool name 'get_recent_memories' combined with sibling tool 'recent' suggests retrieval of historical memory records.

PolicyLayer is an MCP gateway — it sits between your AI agents and Memory-Plus, and nothing reaches the server without passing your rules. This is the rule we recommend for get_recent_memories:
{
"version": "1",
"default": "deny",
"tools": {
"get_recent_memories": {}
}
}get_recent_memories is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_recent_memories. It is categorised as a Read tool in the Memory-Plus MCP Server, which means it retrieves data without modifying state.
Register the Memory-Plus MCP server in PolicyLayer and add a rule for get_recent_memories: 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 Memory-Plus. Nothing to install.
