Memory MCP Server (Go)
Go implementation of the MCP memory server enabling AI agents to maintain persistent knowledge graphs across sessions — creating and updating entities and relations, storing observations, searching the knowledge graph, and integrating persistent memory into agent workflows that need to remember information between conversations.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Local JSON storage. No credentials. Community Go MCP. No external exposure.
⚡ Reliability
Best When
An agent needs persistent knowledge graph memory across sessions — Go binary provides fast startup and low resource usage compared to Node.js reference implementation.
Avoid When
You need semantic/vector search memory, large-scale knowledge storage, or are comfortable with the official @modelcontextprotocol/server-memory Node.js implementation.
Use Cases
- • Storing facts and relationships from information gathering agents
- • Maintaining user preference memory from personalization agents
- • Building knowledge graphs from research and analysis agents
- • Persisting entity relationships across conversation sessions from long-running agents
- • Remembering past decisions and context from workflow agents
- • Creating structured memory stores from autonomous agents
Not For
- • Vector/semantic search (this is graph-based, not embedding-based memory)
- • Large-scale knowledge bases (local file storage not suitable for enterprise scale)
- • Teams preferring the official Node.js memory server reference implementation
Interface
Authentication
No authentication — local Go binary with file-based JSON storage. Data stored locally. No external service dependencies.
Pricing
Free open source Go MCP server. Self-hosted locally. No external service costs.
Agent Metadata
Known Gotchas
- ⚠ Go binary must be compiled or downloaded — slightly more setup than npm-based servers
- ⚠ Knowledge graph stored in local JSON file — not suitable for large graphs
- ⚠ Entity and relation schema follows official memory server spec — check for tool name changes
- ⚠ Community Go implementation — may lag behind official spec updates
- ⚠ No semantic search — exact entity/relation lookups only
- ⚠ Data file path must be configured — default path may conflict with other instances
