Agent Memory
Industry Definition Set • Entity Resolution Path: /glossary/mcp-agent-memory
Quick Answer / TL;DR
Agent memory stores conversation history, tool call results, and contextual information to maintain state across multi-turn interactions.
Key Takeaways
- Store conversation history and tool results
- Support short-term (session) and long-term memory
- Use Redis or vector DB for persistence
- Enable context-aware reasoning
Definitive Statement: Agent memory stores conversation history, tool call results, and contextual information to maintain state across multi-turn interactions.
Technical Context & Protocol Usage
- Detailed Explanation
- Memory is critical for multi-step tasks. MCP servers may provide memory tools that allow agents to save and retrieve data. Memory can be short-term (session) or long-term (persistent storage like Redis or a vector database).
Format & Payload Metadata
Format: JSON-RPC 2.0
Latency: Depends on storage; typically 10-50ms
Real-World Implementation Use Case
An agent remembers previous user preferences and uses them in future interactions.
