Memory MCP Server Go

okooo5km/memory-mcp-server-go

A Model Context Protocol server that provides knowledge graph management capabilities. This server enables LLMs to create, read, update, and delete entities and relations in a persistent knowledge graph, helping AI assistants maintain memory across conversations. This is a Go implementation of the official TypeScript Memory MCP Server.

Features

  • High-Performance Storage: SQLite backend with WAL mode, read/write connection separation for concurrent access

  • Knowledge Graph Management: Persistent graph of entities, relationships, and observations

  • Advanced Search: FTS5 full-text search with BM25 ranking, synonym expansion, and time-decay scoring

  • Graph Traversal: Search results include 1-hop related entities for richer context

  • Entity Management: Merge duplicate entities, update types, modify observations, detect conflicts

  • Observation Metadata: Track source, confidence, and tags for each observation

  • MCP Resources & Prompts: AI clients can passively load graph summaries and use guided memory workflows

  • Flexible Transport: Supports stdio, SSE, and Streamable HTTP with optional Bearer or OAuth 2.1 authentication

  • Seamless Migration: Automatic upgrade from JSONL to SQLite with zero intervention

  • Cross-Platform: Pure Go SQLite (no CGO required), works on Linux, macOS, and Windows
