Databases - official Oracle server
MySQL MCP server
Python MCP server for managing connections to MySQL AI and MySQL HeatWave, running SQL, using HeatWave ML/GenAI features such as RAG and natural-language-to-SQL, managing vector stores and browsing OCI Object Storage. It runs locally from oracle.mysql-mcp-server (pypi); the notes below cover how it authenticates.

Notes and caveats
- Oracle states it is not intended for production use and is a proof of concept.
- Runs over stdio.
- Requires a database connection config file (MYSQL_MCP_CONFIG); an OCI config is only needed for OCI-dependent features such as Object Storage and compartments.
