Environment / auth

IONOS_TOKEN
required
secret
IONOS CLOUD API token (required for all products except Object Storage)
IONOS_S3_ACCESS_KEY
secret
S3 access key for IONOS Object Storage
IONOS_S3_SECRET_KEY
secret
S3 secret key for IONOS Object Storage
IONOS_MCP_LOAD_MODE
Tool registration strategy (the --load-mode flag overrides this). 'eager' (default): register all tools at startup. 'lazy': defer Compute and Object Storage behind 'ionos_load_compute_tools' / 'ionos_load_objectstorage_tools' sentinel tools (requires MCP client support for notifications/tools/list_changed). 'dynamic' (alias 'search'): expose only the ionos_search_tools / ionos_describe_tools / ionos_call_tool meta-tools and browse the full catalog through them — for clients with hard tool caps and no tool search of their own (Cursor, Windsurf).
IONOS_MCP_TOOL_SCOPE
Opt in to write operations. Unset (default) leaves the server read-only: only list_/get_/head_ tools are registered. 'write' additionally registers create_/update_ tools and the non-disruptive actions (start_, resume_, attach_, assign_); 'destructive' also registers delete_ and the disruptive actions (stop_, reboot_, suspend_, upgrade_, restore_, detach_, recreate_, import_) and implies 'write'. Comma-separated, case-insensitive, hierarchical; unrecognised values stay read-only. WARNING: enabling this lets an AI model provision, modify and delete billable resources in a live IONOS CLOUD account. Every create and delete requires a two-phase confirmation, but that cannot stop a client configured to approve tool calls automatically. Leave unset unless writes are needed.
