Allow hiding/removing unused cloud connectors (Gmail, Google Calendar, etc.)

Description

Cloud connectors (Gmail, Google Calendar, Google Drive) appear as MCP servers in Claude Code even when they are not connected and not needed. They show up with "Needs authentication" status and there is no way to hide or remove them.

Example:

claude.ai Gmail: https://gmail.mcp.claude.com/mcp - ! Needs authentication
claude.ai Google Calendar: https://gcal.mcp.claude.com/mcp - ! Needs authentication

Problem

• These are built-in platform connectors that cannot be removed via CLI (claude mcp remove) or local settings
• Users who don't use these services have no way to declutter their MCP server list
• They add noise to the tool/MCP server listing

Requested Feature

Provide an option to hide or disable unused cloud connectors, either:

• Via claude mcp remove CLI command
• Via a setting in settings.json (e.g., blockedMcpServers or similar)
• Via the claude.ai Connectors UI (a "Hide" or "Remove" option for unconnected connectors)

Environment

• Claude Code CLI
• macOS
