Self-hosted PlanetScale MCP alternatives
PlanetScale's MCP server runs only as a managed endpoint, with no build you install and run yourself. If you need the database server process and its credentials on your own machine or network, you need a different one.
Every server below installs locally and talks to your agent over stdio. The connection still reaches whatever database you point it at, but the MCP process and its DSN stay on infrastructure you control.
The 8 best self-hosted alternatives
Bytebase DBHub runs an agent against a SQLite file with execute_sql and search_objects, all from a local process. Zero-dependency, and the database itself is just a file on your disk.
Set up SQLite (DBHub) →DBHub also self-hosts as a Postgres gateway: pass a DSN and the agent runs execute_sql and search_objects. The server stays local even when the database is remote.
Set up DBHub (Postgres) →Supabase's server installs locally and runs SQL, inspects schema, reads logs, and manages edge functions against a project, from a process you operate yourself.
Set up Supabase →Document data instead of relational rows fits MongoDB's official server, which runs locally and queries and manages databases plus Atlas clusters. The model differs from PlanetScale's MySQL, but the server is yours to host.
Set up MongoDB →Analytical querying stays on your own infrastructure with ClickHouse's official server, which installs locally, lists databases and tables, and runs read-only SQL against a cluster.
Set up ClickHouse →Run Elastic's official server yourself to list indices, read mappings, and run search and ES|QL against a cluster, with the server process under your control.
Set up Elasticsearch →Redis's official server runs locally and reads and writes strings, hashes, lists, streams, JSON, and vector search. It is a self-hosted data-structure layer rather than a relational replacement.
Set up Redis →For graph data, Neo4j's official server installs locally, introspects the graph schema, and runs read or write Cypher against any deployment, including one on your own machine.
Set up Neo4j →
How to choose
All of these run as a local stdio process, which is exactly what PlanetScale's hosted-only server does not offer. DBHub on SQLite or Postgres and Supabase are the closest SQL options; Mongo, ClickHouse, Elasticsearch, Redis, and Neo4j fit when your data model matches. In every case the server and DSN live on your infrastructure, even if the database itself is remote.
FAQ
- Can the PlanetScale MCP server be self-hosted?
- No. PlanetScale offers only a hosted server, with no self-installable build. If running the server yourself is a hard requirement, you have to choose one of the alternatives that ships a local stdio command.
- Does self-hosting the server keep my data local?
- It keeps the MCP process and its DSN on your infrastructure, which is usually the point for audit and access control. Whether the data is local depends on the database: a SQLite file stays on disk, while a remote Postgres or Mongo cluster is still reached over the network.
