Search memories using hybrid semantic + keyword search. Returns ranked results combining full-text matching and vector similarity.
AI agents call memory.recall to retrieve information from Sovereign Universal Memory MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
memory.recall performs a search operation that queries and retrieves data without altering, deleting, or executing external operations. This is a pure read operation analogous to querying a database for information. The ranked results returned are informational only, making it Read category with low severity since memory systems pose minimal risk when only searched.
From the tool's definition Tool description states it 'Search memories using hybrid semantic + keyword search. Returns ranked results' with no indication of modification, deletion, or side effects. The action is retrieval-only.
Attacks that exploit this kind of access
Search memories using hybrid semantic + keyword search. Returns ranked results combining full-text matching and vector similarity. It is categorised as a Read tool in the Sovereign Universal Memory MCP MCP Server, which means it retrieves data without modifying state.
Register the Sovereign Universal Memory MCP server in PolicyLayer and add a rule for memory.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 Sovereign Universal Memory MCP. Nothing to install.
memory.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 memory.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 memory.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.
memory.recall is provided by the Sovereign Universal Memory MCP server (nnaveenraju/sovereign-universal-memory-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
