What is mariadb-mcp-server?

mariadb-mcp-server is an MCP (Model Context Protocol) server that enables AI assistants like Claude to execute read-only SQL queries against a MariaDB database and retrieve its schema. It is intended for developers who want to query MariaDB through MCP-compatible clients.

How to use mariadb-mcp-server?

Install MariaDB Connector/C (on macOS using Homebrew), set the required environment variables (MARIADB_HOST, MARIADB_USER, MARIADB_PASSWORD, MARIADB_DATABASE, MARIADB_PORT), and configure your MCP client (e.g., Claude Desktop) with the uv command pointing to the server source. Once configured, use the query_database tool to run read-only queries.
