Self-hosted Supabase MCP alternatives
The Supabase MCP server already installs locally and talks to your agent over stdio, so it keeps the server process and credentials on your own machine. What it cannot change is its engine: it targets a Supabase project specifically. If you want a local server pointed at a different database, you need a different one.
Every server below runs over stdio as well. One caveat worth stating: self-hosting controls where the process and connection details live, but queries still reach whichever database you point at, whether that sits on your own hardware or a managed cloud.
The 8 best self-hosted alternatives
The lightest of the set, the SQLite server through Bytebase DBHub runs an agent against a local database file with execute_sql and search_objects. No server to operate, just a file on disk.
Set up SQLite (DBHub) →DBHub connects an agent to any Postgres instance via a DSN over stdio, so a self-managed Postgres on your own box is reachable. It runs SQL and searches objects without tying you to a managed project.
Set up DBHub (Postgres) →MongoDB's official server installs locally and queries and manages databases, with Atlas administration when you need it. Its document-oriented find and aggregate tools fit data that does not belong in relational tables.
Set up MongoDB →Pointed at a self-hosted cluster, ClickHouse's official server lists databases and tables and runs read-only SQL. The column-oriented engine answers analytics queries far faster than a transactional database can.
Set up ClickHouse →Elastic's official server runs locally and lists indices, reads mappings, and runs full-text and ES|QL queries against a cluster you operate. It is the search engine to reach for when SQL filtering is not enough.
Set up Elasticsearch →For in-memory state on your own infrastructure, Redis's official server reads and writes strings, hashes, lists, streams, JSON, and vector search over stdio. It complements a primary database rather than replacing it.
Set up Redis →Run it against your own Neo4j deployment and the official server introspects a graph schema and runs read or write Cypher. Connected data and traversals are where it earns its place over a relational store.
Set up Neo4j →For a distributed SQL engine handling both transactional and analytical queries, the SingleStore official server runs SQL on workspaces, manages starter workspaces and Stage files, and orchestrates notebooks and jobs from a process you control.
Set up SingleStore →
How to choose
All of these run as local stdio servers, so the difference is the engine, not the hosting. For a self-managed Postgres, DBHub connects by DSN; SQLite covers the local-file case. ClickHouse and SingleStore handle analytics, Elasticsearch handles search, MongoDB handles documents, Neo4j handles graphs, and Redis handles caching. Remember the process is local but the queries still travel to wherever the database itself lives.
FAQ
- Is the Supabase MCP server self-hosted?
- The server itself installs and runs locally over stdio, so the process and credentials stay on your machine. It does, however, target a Supabase project, so the underlying data sits on Supabase's managed platform unless you run Supabase yourself.
- Does running the database MCP server locally keep my data on my own machine?
- It keeps the MCP server process and connection details local, which is usually the point for credential control. The queries still reach whatever database you connect to. If you also self-host that database (Postgres, ClickHouse, Neo4j), then the data stays on your infrastructure too.
