MCP server for LenelS2 S2 NetBox access control via the NBAPI. Read-only by default.
Today is the operative word: we check S2 Netbox MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

This one needs environment variables set before it will start:
NETBOX_BASE_URL (Base URL of the S2 NetBox controller's web interface, e.g. https://netbox.example.internal (no trailing slash or path)), NETBOX_USERNAME (NBAPI session-login username), NETBOX_PASSWORD (NBAPI session-login password), NETBOX_ENABLE_WRITES (Set to true/1/yes to register the write tools (lock/unlock, add/modify/delete). Unset keeps the server strictly read-only.), NETBOX_ENABLE_DESTRUCTIVE (Set to true/1/yes together with NETBOX_ENABLE_WRITES to additionally register the 11 destructive (delete/remove) tools).
