Tool	Type	What it does
`lambda_list_instances`	read	List instances List your running GPU cloud instances (id, name, ip, status, region, instance_type, ssh_key_names, filesystems, jupyter_url). Lambda Cloud REST: GET /api/v1/instances.
`lambda_get_instance`	read	Get instance Get full details of a single instance by id (status, ip, region, instance_type, ssh/filesystem attachments, jupyter url, available actions). Lambda Cloud REST: GET /api/v1/instances/{id}.
`lambda_list_instance_types`	read	List instance types List all GPU instance types with their specs (vcpus, memory, storage, gpus), hourly price (price_cents_per_hour), and which regions currently have capacity available. Use this to pick region_name + instance_type_name before launching. Lambda Cloud REST: GET /api/v1/instance-types.
`lambda_list_images`	read	List images List available machine images (id, name, family, version, region availability) that can be selected when launching an instance. Lambda Cloud REST: GET /api/v1/images.
`lambda_list_filesystems`	read	List filesystems List your persistent filesystems (id, name, region, status, created_at) that can be attached to instances at launch. Lambda Cloud REST: GET /api/v1/file-systems.
`lambda_list_firewall_rules`	read	List firewall rules List the account's inbound firewall rules (protocol, port range, source CIDR, description). Lambda Cloud REST: GET /api/v1/firewall-rules.
`lambda_list_firewall_rulesets`	read	List firewall rulesets List firewall rulesets (id, name, region, rules) that can be applied to instances. Lambda Cloud REST: GET /api/v1/firewall-rulesets.
`lambda_get_firewall_ruleset`	read	Get firewall ruleset Get a single firewall ruleset by id. Lambda Cloud REST: GET /api/v1/firewall-rulesets/{id}.
`lambda_list_audit_events`	read	List audit events List account audit-log events, optionally filtered by time window and resource type, with page_token pagination. Lambda Cloud REST: GET /api/v1/audit-events.
`lambda_launch_instance`	write	Launch instance Launch one or more GPU cloud instances. COSTS MONEY: billing starts as soon as the instance boots (hourly rate per instance_type). Pick region_name + instance_type_name from lambda_list_instance_types (only regions with capacity available), and pass exactly one existing SSH key name in ssh_key_names (create keys in the Lambda dashboard). Lambda Cloud REST: POST /api/v1/instance-operations/launch.
`lambda_restart_instances`	write	Restart instances Restart one or more running instances by id (a reboot — the instances are NOT destroyed and billing continues). Lambda Cloud REST: POST /api/v1/instance-operations/restart.
`lambda_terminate_instances`	write	Terminate instances Terminate (permanently destroy) one or more instances by id. This STOPS billing for them but DESTROYS the instances and any non-persistent data — persistent filesystems survive. Irreversible. Lambda Cloud REST: POST /api/v1/instance-operations/terminate.
`lambda_update_instance`	write	Update instance Update a live instance's name and/or tags. Only provided fields are changed. Lambda Cloud REST: POST /api/v1/instances/{id}.
`lambda_create_filesystem`	write	Create filesystem Create a new persistent filesystem in a region (can then be attached to instances at launch). Lambda Cloud REST: POST /api/v1/filesystems.
`lambda_delete_filesystem`	write	Delete filesystem Delete a persistent filesystem by id. Irreversible — DESTROYS all data on it. The filesystem must not be attached to any instance. Lambda Cloud REST: DELETE /api/v1/filesystems/{id}.
`lambda_usage_status`	meta	Usage status (free-tier meter) Report the caller's current free-tier usage this month: calls used, monthly limit, remaining, and whether the cap is reached.
`lambda_upgrade`	meta	Upgrade to Pro (unlimited) Subscribe to Pro for unlimited tool calls, monthly ($9) or yearly ($90). Returns a Stripe Checkout link.
