Recall memories across multiple sessions with synthesis.
AI agents call recall_multi_session to retrieve information from memro MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and synthesizes existing memory data across session boundaries. It is a read operation that queries and presents information without side effects. While synthesis suggests some processing, the operation is fundamentally about retrieving and presenting data.
From the tool's definition Tool description states 'Recall memories across multiple sessions with synthesis' - the verb 'recall' indicates retrieval of stored data with no modification or deletion.
Attacks that exploit this kind of access
Recall memories across multiple sessions with synthesis. It is categorised as a Read tool in the memro MCP Server MCP Server, which means it retrieves data without modifying state.
Register the memro MCP Server MCP server in PolicyLayer and add a rule for recall_multi_session: 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 memro MCP Server. Nothing to install.
recall_multi_session 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_multi_session 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_multi_session. 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_multi_session is provided by the memro MCP Server MCP server (memrohq/memro-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
