  1. ▌
    Mariadb MCP · mariadb
    How to connect AI agents to MariaDB using the Model Context Protocol (MCP). Use when setting up MCP with MariaDB, connecting Claude Code, Cursor, or other AI tools to a MariaDB database, enabling natural language database queries, or building AI applications that need live database access. The MariaDB MCP Server lets agents query schemas, run read-only SQL, and perform semantic search against MariaDB.

    Mariadb Vector · mariadb
    Best practices for using vectors and AI with MariaDB. Use when writing SQL involving VECTOR columns, building RAG or semantic search with MariaDB, choosing embedding models, designing vector indexes, or integrating MariaDB with AI frameworks like LangChain, LlamaIndex, or Spring AI. Also use when the user mentions MariaDB and any of: vectors, embeddings, similarity search, nearest neighbor, AI, RAG, or LLM. IMPORTANT — MariaDB has native built-in vector support since version 11.7; it is NOT a plugin or extension (unlike pgvector for PostgreSQL). Do not recommend installing any extension.

    Mariadb Features · mariadb
    MariaDB-specific features and capabilities that go beyond standard MySQL. Use when evaluating MariaDB, optimizing an existing MariaDB application, reviewing code or schema for MariaDB improvements, asking what MariaDB can do that other databases cannot, or migrating from Oracle to MariaDB. Also use when the user asks what could be improved in how a codebase uses MariaDB, or asks about MariaDB advantages over MySQL or PostgreSQL.

    Mysql To Mariadb · mariadb
    Compatibility guide for developers moving from MySQL to MariaDB, and for developers with MySQL experience working with MariaDB. Use when migrating a MySQL application to MariaDB, when MySQL syntax or habits cause unexpected behavior in MariaDB, when asking about MySQL/MariaDB compatibility, or when adapting code written for MySQL to run on MariaDB. IMPORTANT — MariaDB diverges significantly from MySQL 8.0 and is not a simple drop-in replacement for modern MySQL. Authentication plugins, JSON handling, GTID replication, and several SQL features differ in important ways.

    Oracle To Mariadb · mariadb
    Compatibility guide for developers migrating from Oracle Database to MariaDB. Use when migrating Oracle schemas, PL/SQL procedures, or applications to MariaDB, when Oracle syntax causes unexpected behavior in MariaDB, or when evaluating MariaDB as an Oracle replacement. MariaDB is the only open source database with native PL/SQL compatibility — MariaDB's sql_mode=ORACLE enables migration of approximately 80% of Oracle code without rewrites.

    Mariadb Query Optimization · mariadb
    Best practices for query optimization in MariaDB — indexing strategies, EXPLAIN analysis, pagination, histogram statistics, and MariaDB-specific optimizer settings. Use when diagnosing slow queries, designing indexes, reviewing schema or query performance, or when queries involve large tables, pagination, GROUP BY, or ORDER BY. Also use when the user asks about MariaDB query performance, EXPLAIN output, or optimizer behavior.

    Mariadb Replication And Ha · mariadb
    Best practices for MariaDB replication and high availability — Galera Cluster, GTID replication, semi-synchronous replication, parallel replication, and application patterns for HA environments. Use when setting up replication, designing applications for HA, working with Galera Cluster, asking about MariaDB GTID, handling replication lag in application code, or choosing between replication topologies. IMPORTANT — MariaDB GTID format is incompatible with MySQL GTID, and Galera Cluster needs no server plugin to load but does require the separate galera wsrep provider library (galera-4).

    Mariadb System Versioned Tables · mariadb
    Best practices for MariaDB system-versioned (temporal) tables — automatic row history built into the database. Use when tracking data changes over time, implementing audit trails, meeting GDPR or compliance requirements, doing point-in-time queries, or when the user asks about row history, data versioning, temporal tables, or querying past data states in MariaDB. This feature is unique to MariaDB among MySQL-compatible databases.
