10 open-source MCP servers that let your AI agent talk to your database
victor_explore · x · 2026-10-19
A curated list of 10 GitHub MCP server repos for connecting AI agents to databases:
- MCP Toolbox for Databases (Google, 17K stars): supports Postgres, MySQL, SQLite, BigQuery and more; lets you expose only pre-approved queries to the agent.
- DBHub (4K stars): one lightweight server for six SQL databases; few tools means low token usage, with read-only mode.
- Postgres MCP Pro (3K stars): querying plus DBA-style checks—slow query detection, index suggestions, health checks.
- Supabase MCP (3K stars): tables, SQL, migrations and docs.
- Also covers MySQL, Qdrant, MongoDB, ClickHouse, Redis, and MotherDuck DuckDB MCP servers for use cases like vector memory search, plain-language Redis operations, and SQL over CSV/Parquet.
Author recommends read-only mode and limiting tool surfaces for safety and token efficiency.
