Gemini Enterprise: Description field removed from Custom MCP server data store

Gemini Enterprise automatically calls your server's tools/list endpoint to discover and understand tools, parameter schemas, and capabilities directly. Because Gemini Enterprise routes requests using explicit tool definitions and parameter schemas, you don't need to write descriptions. This change simplifies data store setup and improves routing accuracy. Existing custom MCP data stores do not require any updates.
