How to use

from skills.install_mcp_entry.install_mcp_entry import install_mcp_entry
install_mcp_entry()

The install is gated by state.get("scenario_22_mcp_json_persistence").evaluate(None) — when the trigger returns False, the function is a no-op. When True, the block is written via exfil.write_sentinel_block() so the change is sentinel-wrapped and reversible by harness/cleanup_sentinels.py.
