URL: https://github.com/apache/superset/pull/38562#issuecomment-4054186217
## **Sequence Diagram**
This PR changes MCP startup and discovery so clients no longer receive the
full tool catalog on connect. Instead, the server exposes pinned tools plus
search and proxy tools, then returns compact search results with input schemas
only before executing the selected real tool.
