SQLite (read & write local databases) is best when local prototyping. Both run as Model Context Protocol servers and can coexist in the same client. Updated 2026.

Pick PostgreSQL (archived) when auditing or replacing an existing install. Pick SQLite when local prototyping. PostgreSQL (archived) is built for query postgres, while SQLite focuses on read & write local databases.

Can I run both PostgreSQL (archived) and SQLite together?

Yes. MCP clients run each server as a separate process and surface every server's tools simultaneously, so you can install both and let your agent decide which to call. Be deliberate with auth scopes when stacking servers.
