Self-hosted Neo4j MCP alternatives
Neo4j's official server runs locally against your own cluster, so the connection and credentials stay on your infrastructure while an agent introspects the schema and runs Cypher. If you keep that property but no longer need a graph, the question becomes which other self-hostable database server fits your data.
Every option below installs and runs locally over stdio, pointed at a database you operate. The data still lives in whatever engine you connect to; what stays local is the server process and the connection it holds.
The 8 best self-hosted alternatives
SQLite via DBHub points an agent at a single local database file with execute_sql and search_objects. The lightest self-hosted option, no separate database process at all.
Set up SQLite (DBHub) →DBHub connects to your own Postgres over a DSN and exposes execute_sql and search_objects, keeping the server on your machine and the database wherever you run it. The relational counterpart to Neo4j's Cypher.
Set up DBHub (Postgres) →Run it locally and the Supabase community server drives a Postgres project end to end: run SQL, inspect schema, read logs, and manage edge functions, for relational data plus the surrounding platform.
Set up Supabase →Documents rather than a graph fit MongoDB, whose official server runs locally and queries and manages databases with find, aggregate, and count, plus Atlas administration.
Set up MongoDB →For analytics on your own cluster, ClickHouse's official server lists databases and tables and runs read-only SQL, a column store you operate yourself for fast scans over large tables.
Set up ClickHouse →Elastic's official server installs locally and lists indices, reads mappings, and runs full-text and ES|QL queries against a cluster you host, the search-shaped alternative to graph traversal.
Set up Elasticsearch →Run against your own instance, the Redis server reads and writes strings, hashes, lists, streams, JSON, and vector search. A self-hosted cache or fast lookup beside a primary store rather than a Neo4j replacement.
Set up Redis →SingleStore's official server runs SQL on workspaces you control and manages starter workspaces, Stage files, notebooks, and jobs, a distributed SQL engine for teams that self-host their analytics and transactional data together.
Set up SingleStore →
How to choose
All of these keep the server process and credentials on your own infrastructure, the same property Neo4j gives you. For relational data, Postgres and SQLite via DBHub are the cleanest swaps, with Supabase and SingleStore adding platform and scale. MongoDB covers documents, ClickHouse and SingleStore cover analytics, Elasticsearch covers search, and Redis covers caching. One caveat: self-hosting the server controls where the process lives, not where the data lives, which is the database you point it at.
FAQ
- Can the Neo4j MCP server be self-hosted?
- Yes. Neo4j's official server runs locally over stdio against your own deployment, so the process and credentials stay on your infrastructure while the agent runs Cypher. Every alternative on this page also installs and runs locally.
- Does self-hosting the database server keep my data on my own systems?
- It keeps the MCP server process and its connection on your infrastructure. Whether the data stays local depends on the database: SQLite reads a local file, and Postgres, ClickHouse, Elasticsearch, Redis, and SingleStore all keep data wherever you run those engines, which can be entirely on your own systems.
