PlanetScale MCP alternatives
PlanetScale's official MCP server is hosted and closed: it explores organizations, databases, and branches, reads and writes SQL, and pulls query insights against PlanetScale's managed MySQL platform. It is a clean fit if you already run there. People look past it for two reasons: they run a different database engine, or they want a server they can host and audit themselves.
The servers below are the database MCP servers worth comparing against PlanetScale. Most speak SQL; a few cover other data models an agent might query in the same project.
The 8 best alternatives
For a single local database file, Bytebase DBHub points an agent at SQLite with execute_sql and search_objects. Zero-dependency and token-efficient, it is the lightest way to query a database that lives on disk.
Set up SQLite (DBHub) →DBHub also connects to Postgres via a DSN, running execute_sql and search_objects. It is the natural pick if your data sits in Postgres rather than PlanetScale's MySQL.
Set up DBHub (Postgres) →Supabase's server runs SQL, inspects schema, reads logs, and manages edge functions against a project. It suits teams whose Postgres lives inside the Supabase platform.
Set up Supabase →Document data instead of relational tables fits MongoDB's official server, which queries and manages databases and administers Atlas clusters. The model differs from PlanetScale, so reach for it when your data is documents.
Set up MongoDB →Analytical workloads point at ClickHouse's official server, which lists databases and tables and runs read-only SQL against a cluster. It is built for aggregation queries rather than the transactional path PlanetScale serves.
Set up ClickHouse →Full-text and log search fit Elastic's official server: list indices, read mappings, and run search and ES|QL queries. It answers questions SQL on PlanetScale would struggle with.
Set up Elasticsearch →Neon's official server creates projects and branches, runs SQL, and drives safe schema migrations on serverless Postgres. Its branching model is the closest analogue to PlanetScale's branches, on Postgres rather than MySQL.
Set up Neon →For a key-value and structure store, Redis's official server reads and writes strings, hashes, lists, streams, JSON, and vector search. It is a cache and data-structure layer, not a relational replacement for PlanetScale.

How to choose
If you are leaving PlanetScale's MySQL for another relational engine, Neon is the closest by branching model, and DBHub on Postgres or Supabase covers the rest. Mongo, ClickHouse, Elasticsearch, and Redis are different data models worth picking only when your workload matches them. Note that PlanetScale's own server is hosted and closed, so several of these also let you run the server yourself.
FAQ
- What is the closest alternative to the PlanetScale MCP server?
- Neon is the nearest match: serverless SQL with a database branching model much like PlanetScale's, on Postgres instead of MySQL. For a self-hostable option, DBHub points an agent at Postgres or SQLite over a DSN.
- Do these alternatives all speak SQL?
- Most do: DBHub, Supabase, ClickHouse, Neon, and Elasticsearch's ES|QL all run SQL-style queries. MongoDB uses document queries and Redis uses key-value and data-structure commands, so those two are different models entirely.
