get_memories
AI agents call get_memories to retrieve information from Mem0 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 stored memories/data without modifying or deleting anything. It is a read-only query operation. The low severity reflects minimal blast radius—even if an agent misuses it, only data exposure occurs, not destruction or financial impact. Confidence is 0.85 rather than 0.95 because the description is empty, leaving some ambiguity, but the name and context strongly suggest a simple getter.
From the tool's definition Tool name 'get_memories' and sibling tools 'search_memories', 'get_memory', 'list_entities' indicate retrieval operations.

get_memories. It is categorised as a Read tool in the Mem0 MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Mem0 MCP Server MCP server in PolicyLayer and add a rule for get_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 Mem0 MCP Server. Nothing to install.
get_memories 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 get_memories 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 get_memories. 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.
get_memories is provided by the Mem0 MCP Server MCP server (mem0ai/mem0-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
