Best Neo4j MCP Servers
Neo4j is a graph database management system developed by Neo4j, Inc. It is a native graph database that stores data in nodes connected by relationships, providing an efficient way to query connected data.
Why this server?
Search entity relationships and retrieve graph memory from a Neo4j database.
Why this server?
Provides an optional Neo4j backend for storing and querying the code property graph, enabling graph database capabilities.

Tavily MCP Serverofficial
AlicenseAqualityDmaintenanceThis server enables AI systems to integrate with Tavily's search and data extraction tools, providing real-time web information access and domain-specific searches.441,4002,310MITWhy this server?
Provides a graph-based codebase analysis using Neo4j, allowing agents to query code relationships such as callers, dependencies, and impact of changes.
AlicenseAqualityCmaintenanceProvides a graph-based code analysis to coding agents, enabling tools to trace call dependencies, assess change impact, and identify hotspots using tree-sitter and Neo4j.10144MITWhy this server?
Uses Neo4j as the storage backend for the knowledge graph, providing unified graph storage and vector search capabilities.
AlicenseBqualityCmaintenanceScalable, high-performance knowledge graph memory system with semantic search, temporal awareness, and advanced relation management.1712425MITWhy this server?
Serves as the storage backend for the temporal knowledge graph, enabling bitemporal fact management with confidence decay and hierarchical clustering of repository modules.
AlicenseAqualityAmaintenancememex is a developer context-continuity MCP server — it watches your git repos and builds a temporal knowledge graph (modules, symbols, decisions, open problems) via Graphiti + Neo4j, then serves it to any AI coding agent over MCP. Every edge carries a validity window and a confidence score that decays over time. 12 tools across read and write. Install via npx -y stifler-memex-mcp. MIT licensed.1312MIT
