MariaDB MCP Server

Last updated: 2026-05-25

The Model Context Protocol (MCP) lets AI agents connect to external tools and data sources. The MariaDB MCP Server gives agents direct, controlled access to a MariaDB database — reading schemas, running queries, and optionally performing vector/semantic search — without requiring the developer to write integration code.

The server is open source (MIT), maintained by the MariaDB Foundation at github.com/MariaDB/mcp.

Requires: Python 3.11+, uv package manager, MariaDB server.

What Agents Can Do

With the MariaDB MCP Server connected, an agent can:

• List databases and tables
• Read table schemas including foreign key relationships
• Run read-only SQL queries (SELECT, SHOW, DESCRIBE)
• Create databases
• Perform semantic/vector search on stored documents (when embedding provider is configured)
