"""
Manual test for MCP server creation and verification.

This manual test demonstrates creating an MCP server from an MCI schema,
registering tools, and verifying the server can be queried. Run this test
from the terminal to see the full output and verify the server setup.

Usage:
    uv run python testsManual/test_mcp_server.py
