MCP MariaDB Server

The MCP MariaDB Server is a community-maintained Model Context Protocol server that wraps the MariaDB C/Python connectors. It gives an LLM client read (and optionally write) access to a MariaDB database — schema listing, query execution, row inspection — without handing over raw connection strings every turn.

Frequently asked questions

Is this server official?

No — it is community-maintained. MariaDB Foundation does not ship an MCP server; community Python and Go implementations are both common.

Can I point it at MySQL too?

Yes — MariaDB's wire protocol is MySQL-compatible. Most MCP MariaDB servers accept a MySQL DSN, though edge features like columnstore may behave differently.

How do I prevent destructive queries?

Connect with a read-only database user. The MCP server layer is defense in depth, but the database itself is the enforcement boundary.
