DataFrey – MCP server for Snowflake with text-to-SQL agent
Yet another database MCP server, but the CLI setup wizard is genuinely nice.

That’s why I built Gyrus. It's a suite of open source, self hosted agentic frameworks: Frosty for Snowflake, Zeus for SQL Server, and Mick for Postgres.The core philosophy is total control: you host it, you own the credentials, and you choose the model. I am also updating the snowflake agent this week to support open source Gemma 4 models, I ran evaluation against state of the art models, and its performing equally well when it comes to accuracy. Its little slower than them but it gets the job done for Free. I've also implemented a "Safety First" architecture, including hard coded blocks for destructive commands like DROP at the tool level, because in data ops, prompt based safety isn't enough.
