Claude Code: deny. ### `civo_create_dns_record` - The name "civo_create_dns_record" says "create": a word for a change. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Add one record to a Civo-hosted domain. Live DNS changes propagate to the world; undo by deleting the record in the Civo dashboard or CLI. Civo: POST /v2/dns/{domain_id}/records. ``` ### `civo_create_firewall_rule` - The name "civo_create_firewall_rule" says "create": a word for a change. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Add one rule to a firewall — e.g. allow TCP 443 ingress from 0.0.0.0/0. This changes what is reachable on every instance, cluster and load balancer using the firewall, so prefer narrow CIDRs. Undo by deleting the rule in the Civo dashboard or CLI. Civo: POST /v2/firewalls/{id}/rules. ``` ### `civo_reboot_instance` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Reboot one instance. `soft` (default) asks the OS to restart cleanly; `hard` cuts power and boots it again, like pulling the plug — use only when soft does not work. Causes brief downtime. Civo: POST /v2/instances/{id}/soft_reboots or /hard_reboots. ``` ### `civo_set_instance_tags` - The name "civo_set_instance_tags" says "set": a word for a change. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text REPLACE the full tag list of one instance (tags are used for filtering and by load-balancer instance pools, so changing them can move an instance in or out of a pool). Pass the complete desired list; an empty list clears all tags. Civo: PUT /v2/instances/{id}/tags. ``` ### `civo_start_instance` - The name "civo_start_instance" says "start": a word for a change. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Boot a stopped instance. Undoes civo_stop_instance. Civo: PUT /v2/instances/{id}/start. ``` ### `civo_stop_instance` - The name "civo_stop_instance" says "stop": a word for a change. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Power off one instance. Anything it serves goes offline until it is started again with civo_start_instance. A stopped instance is still billed. Civo: PUT /v2/instances/{id}/stop. ``` ## Only reads (16) Looks things up and changes nothing. Claude Code: allow. ### `civo_get_instance` - The name "civo_get_instance" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Fetch one instance: status, size, CPU/RAM/disk, public and private IPs, network, firewall, tags, attached volumes and source image. Passwords are redacted. Civo: GET /v2/instances/{id}. ``` ### `civo_get_kubernetes_cluster` - The name "civo_get_kubernetes_cluster" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Fetch one Kubernetes cluster: status, readiness, conditions, version and available upgrade, pools and their instances, network, firewall, CNI and installed marketplace apps. The kubeconfig is redacted. Civo: GET /v2/kubernetes/clusters/{id}. ``` ### `civo_get_quota` - The name "civo_get_quota" says "get": a word for reading.

Description, as the server wrote it: ```untrusted-server-text List billable usage for a period: each resource's product code, label, region, time span and hours (size_gb for volumes).
