What this is

sqlmc mcp exposes SQL Multicast's engine to an agent over the Model Context Protocol. It is the third face over one implementation: the tools call the same operations layer as the desktop app's editor and the sqlmc verbs. An agent gets the same answers a person does, and the same refusals.

What an agent can usefully do with it today:

• Understand a real schema while writing T-SQL — actual table and column names from an actual database, rather than guessing from the text in front of it.
• Find out what differs across an estate, and get that difference attached to the completion items it is about.

What it deliberately cannot do yet: run anything. There is no tool that executes SQL. That is §8, and it is not built.
