When you ask an AI to write MySQL queries, you must give it the project’s schema. In very large projects a single database can have hundreds of tables. If you feed the whole schema dump to the AI, the context becomes too long and the request often fails.

To fix this, I thought an MCP server could return a neatly compressed schema so SQL generation works better. While learning MCP, I built a server that first fetches a table list and then fetches detailed information only for the tables you need.
