Graph Database MCP Servers — Neo4j, ArangoDB, Neptune, TigerGraph, Dgraph, Memgraph, FalkorDB, NebulaGraph, and More

Graph databases are having a moment in AI. Knowledge graphs, RAG with structured relationships, agent memory — they all benefit from graph traversal that relational databases can’t match. And the MCP ecosystem has noticed. Part of our Databases MCP category.

We found 20+ MCP servers across 12+ graph databases, from major players like Neo4j and Amazon Neptune to specialized engines like FalkorDB and Memgraph. Two databases — Dgraph and ArcadeDB — have gone all-in and built MCP directly into their core product. And since our initial review, ArangoDB now has an official server and NebulaGraph has entered the ecosystem.

Here’s what’s available and what’s worth using.

What changed since March 2026: ArangoDB shipped an official MCP server (Docker image), filling our biggest identified gap. NebulaGraph launched an open-source MCP server. Memgraph’s ai-toolkit more than quadrupled in stars (26→110) with a major architecture overhaul. Neo4j Labs hit v0.6.0 with a new Aura cloud API server. Graphiti reached 29.9K stars and shipped MCP Server 1.0. CodeGraphContext nearly quadrupled to 4,100 stars. TigerGraph expanded to 60+ tools. Rating upgraded from 3.5 to 4/5.

Neo4j

Neo4j dominates the graph database market, and its MCP story reflects that — two servers, both actively maintained.

neo4j/mcp (Official)

The official server from Neo4j Inc. ships 4 tools: get-schema, read-cypher, write-cypher, and list-gds-procedures (when GDS is detected). Recent updates added TLS/HTTPS configuration for HTTP mode, per-request authentication with custom auth headers, and adaptive operation support (the server launches even when optional dependencies like GDS are unavailable).

It works with every Neo4j deployment: Aura (cloud), self-managed, Docker, Desktop, and Sandbox. HTTP mode supports per-request Bearer token or Basic Auth for multi-tenant setups.

Simple, focused, and reliable. If you just need Cypher access via MCP, this is it.

neo4j-contrib/mcp-neo4j (Neo4j Labs)

The Labs server has roughly 3.5x the stars of the official one, which tells you something about community preference. Now at v0.6.0 and actively maintained with regular releases, it ships the same core Cypher tools but bundles four sub-servers:

• mcp-neo4j-cypher — the main Cypher interface
• mcp-neo4j-memory — knowledge graph memory management
• mcp-neo4j-data-modeling — graph schema design and visualization
• mcp-neo4j-cloud-aura-api — NEW: manage Neo4j Aura cloud instances

The GraphRAG and knowledge graph features are what drive the higher star count. The new Aura API server lets agents spin up and manage cloud database instances directly. If you’re building AI agents that need persistent memory in a graph structure, this is more useful than the bare-bones official server.

neo4j-contrib/sandbox-mcp-server

A companion server for managing Neo4j Sandbox instances — list, start, stop, and extend. Useful for development and experimentation, not production.

Amazon Neptune

awslabs/mcp — amazon-neptune-mcp-server (Official)

3 tools: run_query (supports both openCypher and Gremlin), get_schema, and get_status. Supports Neptune Database (openCypher + Gremlin) and Neptune Analytics (openCypher only).

Requires AWS CLI credentials. Install via uvx awslabs.amazon-neptune-mcp-server@latest.

Minimal but functional. The dual openCypher/Gremlin support means you can query Neptune however your data is modeled.

TigerGraph

tigergraph/tigergraph-mcp (Official)

60+ tools (61 counted in the current README) — expanded from 34 at our initial review. Now the highest tool count of any dedicated graph database MCP server. New additions include vector operations (TigerGraph 4.2+), GSQL operations with LLM-powered query generation, and expanded loading job support.

Coverage spans queries, schema management, vertex operations, edge operations, vector search, and UDFs. All tools use pyTigerGraph’s async APIs. Requires TigerGraph 4.1+ and Python 3.10-3.12. Published on PyPI as tigergraph-mcp. Supports LangGraph, CrewAI, and GitHub Copilot Chat integration.

Despite the low star count, the tool breadth is the best in the category for a dedicated server.

custom-discoveries/TigerGraph_MCP (Community)

A community alternative rebuilt on the AG2 agent framework (v3.1). Includes schema introspection, query viewing, and vertex/edge creation. Much less comprehensive than the official server.

Dgraph

Dgraph has gone further than any other graph database — MCP is built directly into the core product.

Dgraph v25+ (Built-in MCP)

Two server modes: mcp (full access) and mcp-ro (read-only). Accessible via the alpha HTTP endpoint or Go code. All enterprise features are now free.

No separate installation, no configuration, no additional dependencies. Start Dgraph, and MCP is there. Works with Cursor, Windsurf, and Claude Desktop. Now at v25.4.0 (July 2026).

johnymontana/dgraph-mcp-server (Community)

4 tools: execute DQL query, execute mutation, alter schema, get schema. A standalone option if you’re on an older Dgraph version without built-in MCP.

FalkorDB

FalkorDB/FalkorDB-MCPServer (Official)

FalkorDB is a Redis-based graph database using GraphBLAS for fast linear algebra operations on graphs. The MCP server now offers query operations (read-only and standard), graph management (list, delete), data creation, and relationship management. Read-only mode via GRAPH.RO_QUERY for safe agent access. New Streamable HTTP transport mode enables remote access with API key authentication.

Available via npm (@falkordb/mcpserver@latest) or Docker. Can run locally or in the cloud as a hybrid service.

Memgraph

memgraph/ai-toolkit — mcp-memgraph (Official)

More than quadrupled in stars (26→110) since our initial review, reflecting a major architecture overhaul. The ai-toolkit now bundles four packages: memgraph-toolbox (core), langchain-memgraph, mcp-memgraph, and unstructured2graph.

The MCP server ships two implementations: memgraph-production (stable) and memgraph-experimental (testing ground for sampling, elicitation, and adaptive index management). 14 tools backed by memgraph-toolbox include graph analytics (PageRank, betweenness centrality), vector search (search_node_vectors), and standard query/schema operations.

New stricter read-only mode blocks write operations by default. HTTP is now the default transport (replaces stdio). Memgraph Lab also ships a built-in MCP Client that bridges Memgraph with external MCP servers (GitHub, AWS, Tavily).

No other graph MCP server gives agents direct access to graph algorithms. If your use case involves ranking nodes, finding central entities, or similarity search, this is the most capable option.

ArangoDB

ArangoDB is a multi-model database (graph + document + key-value), and its MCP story has improved significantly — ArangoDB now has an official MCP server, filling the biggest gap we identified in our initial review.

arangodb/mcp-arangodb (Official) — NEW

The gap is filled. ArangoDB shipped an official MCP server as a Docker image. It enables AI assistants to generate and execute AQL queries based on natural language, with lightweight schema discovery and manuals to ground queries in actual database structure. Documented at docs.arango.ai.

Deploy via docker run -i --rm --network host arangodb/mcp-arangodb:latest with environment variables for host, credentials, and database name. Supports SSL configuration.

ravenwits/mcp-server-arangodb (Community)

Grew from 7 to 31 tools since our initial review, spanning query (AQL execute/read-only/validate/explain), discovery, collections, documents (including bulk insert/update up to 1,000 docs), indexes, ArangoSearch views/analyzers, graph management (create, insert edge, traverse, shortest path), and backup to JSON. Works with Claude Desktop and Cline/VSCode. Available via npm (arango-server). Designed for local development — the README explicitly discourages production use for security reasons.

PCfVW/mcp-arangodb-async (Community)

46 tools across 11 categories. The highest tool count of any server in this review. Async-first architecture, multi-tenancy with environment switching, flexible content conversion (JSON, Markdown, YAML, Table), backup/restore, analytics, and Docker Compose deployment.

Despite the low star count, the feature set is ambitious. If you need comprehensive ArangoDB management via MCP, this remains the most feature-rich option.

Apache AGE (PostgreSQL Graph Extension)

Apache AGE adds graph capabilities to PostgreSQL using Cypher queries. Two community MCP servers exist:

• veloper/agemcp (Python) — Multi-graph management, vertex/edge upsert, graph removal, and HTML visualization via vis.js/pyvis. Installable via pipx.
• rioriost/homebrew-age-mcp-server (Python) — Read-only by default with --allow-write flag. Bridges Claude with PostgreSQL/AGE.

If you’re using PostgreSQL and want graph capabilities without a separate database, AGE + one of these MCP servers is a pragmatic choice.

NebulaGraph — NEW

nebula-contrib/nebulagraph-mcp-server

New since our initial review. The first MCP server for NebulaGraph 3.x, built on FastMCP. Provides seamless access to NebulaGraph for schema exploration, query execution, and shortcut graph algorithms. Available on PyPI (nebulagraph-mcp-server). Designed to facilitate GraphRAG and agentic workflow research.

NebulaGraph describes this as the “first foundational component in the NebulaGraph X MCP ecosystem,” suggesting more integrations are planned.

Other Graph Databases

ArcadeDB (ArcadeData/arcadedb) — Multi-model database (graph, document, key-value, time-series, vector) with a built-in MCP server. Supports SQL, Cypher, Gremlin, and MongoDB query language. Like Dgraph, no separate installation needed.

Ontotext GraphDB — keonchennl/mcp-graphdb (~16 stars, JavaScript) provides read-only SPARQL access to RDF repositories. 2 tools: sparqlQuery and listGraphs. If you’re in the semantic web / RDF world, this is the only option.

No MCP servers found for: JanusGraph, TerminusDB, or TypeDB.

Knowledge Graph MCP Servers

For general-purpose knowledge graphs (not tied to a specific database):

• Graphiti by Zep (~29,900 stars) — MCP Server 1.0 shipped (mcp_server package at v1.0.2). Temporal knowledge graph engine now supports Neo4j, FalkorDB, Amazon Neptune, and (deprecated, being phased out) KuzuDB backends. Multi-LLM provider support (OpenAI, Anthropic, Google, Groq, Azure). Single-container setup with bundled FalkorDB, YAML config, health check endpoints. See our separate Graphiti review.
• MCP Knowledge Graph Memory Server (part of modelcontextprotocol/servers) — Official Anthropic reference implementation using a local JSON-file knowledge graph. Entities, relations, observations.
• CodeGraphContext (~4,100 stars, Python) — Nearly quadrupled (1,100→4,100). Indexes code into a graph database for code analysis (call chains, dead code, complexity). Now at v0.5.8 with 1,700+ commits. Supports KuzuDB, FalkorDB, and Neo4j backends. 23 language parsers. Interactive web-based visualization.

Comparison Table

*Stars for parent/monorepo, not the MCP server specifically.

What’s Missing

**No official ArangoDB server.** FIXED. ArangoDB now ships an official MCP server as a Docker image.

JanusGraph and TerminusDB have nothing. Two popular graph databases with zero MCP presence.

Graph algorithm access is rare. Only Memgraph exposes graph algorithms (PageRank, centrality, vector search) as MCP tools. Neo4j’s GDS integration exists but is limited. Most servers treat graph databases as query endpoints rather than analytics platforms.

No cross-database graph federation. There’s no MCP server that can query across multiple graph databases or bridge property graph and RDF models. Graphiti’s multi-backend support (Neo4j, FalkorDB, Neptune, plus deprecated KuzuDB) is the closest thing, but it’s a knowledge graph layer, not a federation tool.

The Bottom Line

The graph database MCP ecosystem is stronger than ever. Most major graph databases have official servers, two (Dgraph, ArcadeDB) have built MCP directly into their core product, and ArangoDB has filled the biggest gap from our initial review by shipping an official server.

If you use Neo4j: Start with the official server for basic Cypher access. Use the Labs server if you need GraphRAG, knowledge graph memory, or Aura cloud management.

If you need graph analytics: Memgraph’s server is the only one with built-in PageRank, centrality, and vector search — and it more than quadrupled in community adoption.

If you want maximum tool coverage: TigerGraph (60+ tools) or ArangoDB async (46 tools) lead the pack.

If you want zero-install simplicity: Dgraph v25+ and ArcadeDB both ship MCP built into the database.

If you need a knowledge graph layer: Graphiti (29.9K stars) now supports four database backends and shipped MCP Server 1.0.

Rating: 4 out of 5. Upgraded from 3.5. ArangoDB’s official server fills the biggest previous gap. NebulaGraph adds coverage to the ecosystem. Memgraph’s surge (+323% stars) and architecture overhaul show the category is maturing. Neo4j Labs at 979 stars with four sub-servers demonstrates depth. Still loses a point for missing JanusGraph/TerminusDB and limited graph algorithm exposure outside Memgraph.
