We've also created an open source MCP server FOR PostgreSQL (works with any greenfield app or existing database) called pgedge-postgres-mcp (https://github.com/pgEdge/pgedge-postgres-mcp) - questions & feedback are very welcome here as well.
This February, there'll be a webinar scheduled with the engineer behind the project. He'll be answering questions, both ones asked here in this thread and ones asked at the end of the session during a Q&A.
Keep an eye out here for it to be scheduled: https://www.pgedge.com/webinars
Let's make this interesting for everyone - reply or reach out to community (at) pgedge.com if you have a question or feedback
