Self-hosted Elasticsearch MCP alternatives
Elastic's server runs locally over stdio and points at a cluster you operate, so the process and credentials stay on your side. If you want that same arrangement against a different store, every server below also installs on your own machine and connects to a database you run.
What travels off your network depends on where the database itself lives. A local SQLite file or a self-managed cluster keeps the data with you; a server pointed at a hosted backend sends queries to that backend's API. The list spans SQL engines, a document store, key-value, columnar analytics, and a graph database.
The 8 best self-hosted alternatives
A SQLite database is a file on your disk, and Bytebase DBHub runs SQL against it with a zero-dependency server, the most fully local option here: both the data and the process stay on your machine.
Set up SQLite (DBHub) →DBHub connects to Postgres via a DSN with execute_sql and search_objects. Point it at a Postgres instance you host and both the server and the database run on your own infrastructure.
Set up DBHub (Postgres) →Installing locally, the Supabase server runs SQL, inspects schema, reads logs, and manages edge functions, though it talks to a Supabase project rather than a database purely on your hardware.
Set up Supabase →MongoDB's official server runs on your machine and queries and manages databases, with Atlas administration when you use it. Aimed at a self-run MongoDB, the documents stay where you host them.
Set up MongoDB →Running locally, the ClickHouse server lists databases and tables and runs read-only SQL against a cluster, the columnar-analytics option that keeps both server and data on infrastructure you control.
Set up ClickHouse →For caching and fast key-value access, the Redis server installs locally and reads and writes strings, hashes, lists, streams, and JSON, with vector search, against a Redis instance you run.
Set up Redis →Neo4j's server runs on your machine, introspects a graph schema, and runs read or write Cypher against any Neo4j deployment, including a self-hosted one, for relationship-heavy data.
Set up Neo4j →A self-installable option for SQL at analytical scale, the SingleStore server runs locally and executes SQL on workspaces, manages Stage files, and orchestrates notebooks and jobs.
Set up SingleStore →
How to choose
All of these install and run on your own machine, the same as Elastic's server. How much stays on your network depends on the database: DBHub against local SQLite or a self-run Postgres, ClickHouse, MongoDB, Redis, or Neo4j keeps the data with you, while Supabase and SingleStore reach their own backends. Choose by query shape, then confirm the database lives where you need it to.
FAQ
- Can the Elasticsearch MCP server be self-hosted?
- Yes. Elastic's server runs locally over stdio and connects to a cluster you operate, so the process and credentials stay on your infrastructure. Every alternative here also installs on your own machine and points at a database you run.
- Do these keep my data on my own infrastructure?
- Only if the database does too. DBHub against local SQLite or a self-run Postgres, plus self-hosted ClickHouse, MongoDB, Redis, and Neo4j, keep the data with you. Supabase and SingleStore run the server locally but query their own managed backends.
