"""
Tests for project settings MCP tools.

This test suite covers the new MCP tools for editing project settings:
- get_workspace: Retrieve workspace branding/styling settings
- update_workspace: Modify workspace branding/styling settings
- list_access_controls: List access control settings for all secured stages
- update_access_control: Update access control for a specific stage
- update_stage: Update stage metadata properties

These tools allow SmartChat to modify workspace branding, stage properties,
and access controls through dedicated MCP tools instead of direct file editing.
