Implementation Reference
- server.py:268-271 (registration)Registration of the nmap_vulnerability_scan tool using FastMCP @app.tool decorator.
@app.tool( name="nmap_vulnerability_scan", description="Run vulnerability detection scripts" ) - server.py:272-290 (handler)The main handler function that constructs Nmap arguments for vulnerability scripts based on parameters and executes via run_nmap_command.

Used by all nmap tools including this one.
