Free MCP servers for Postgres and SQLite
@ai-supply · 3mo ago
Why a database MCP server
Instead of pasting schemas and rows into prompts, a database MCP server lets your agent query Postgres or SQLite directly — with the access you grant.
What to look for
- Read-only by default — start with SELECT-only access.
- Parameterized queries — never string-concatenate model input into SQL.
- Scoped credentials — a limited DB role, not your admin user.

Free, open-source database MCP servers are published in the catalog, each security-scanned with a score and grade — important when you're handing an agent query access. Browse the data category and the MCP kind on the categories page.
Connect one in a minute via the agent quickstart — and keep it read-only until you trust it.
