Delete a Grail fieldset by UID (WRITE, Storage Fieldsets v1).
AI agents call delete_fieldset to permanently remove resources in Dynatrace SaaS MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deletion of a fieldset is an irreversible operation that destroys data configuration. Even though the API spec labels it WRITE, the actual effect is permanent removal of a storage structure, which cannot be undone without restore/backup. This qualifies as Destructive per the rules: 'irreversibly deletes or overwrites data, or actions that cannot be undone'.
From the tool's definition Tool name explicitly contains 'delete'; description states 'Delete a Grail fieldset by UID'. The API classification '(WRITE, Storage Fieldsets v1)' is contradictory but the action itself is irreversible deletion.

Register the Dynatrace SaaS MCP Server MCP server in PolicyLayer and add a rule for delete_fieldset: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Dynatrace SaaS MCP Server. Nothing to install.
delete_fieldset is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the delete_fieldset rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
