AI agents call recall to retrieve information from Memoraeu without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves/queries stored memories using semantic search. It is a read-only operation that does not create, modify, delete, or execute code. The worst case misuse would be unauthorized access to stored memories, but the tool itself has low blast radius since it cannot alter state or trigger external actions. Classified as Read/low severity.
From the tool's definition Tool name 'recall' with description 'Semantic search through memories in natural language' — performs data retrieval without modification or side effects.
Attacks that exploit this kind of access
Semantic search through memories in natural language. It is categorised as a Read tool in the Memoraeu MCP Server, which means it retrieves data without modifying state.
Register the Memoraeu MCP server in PolicyLayer and add a rule for recall: 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 Memoraeu. Nothing to install.
recall 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 recall 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 recall. 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.
recall is provided by the Memoraeu MCP server (pquattro/memoraeu-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
