List all Grail fieldsets (Storage Fieldsets v1). A fieldset is a curated, named list of field names
AI agents call list_fieldsets to retrieve information from Dynatrace SaaS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and returns metadata about available fieldsets in Dynatrace's Grail storage system. It has no side effects, does not execute code or scripts, does not modify data, and does not destroy or create anything. The blast radius of an AI agent misusing this tool is minimal—at worst, it could retrieve metadata it shouldn't have access to, but cannot take destructive or financial actions.
From the tool's definition Tool name 'list_fieldsets' and description 'List all Grail fieldsets' indicates a read-only operation that retrieves and enumerates field definitions without modifying, executing operations, or deleting data.

List all Grail fieldsets (Storage Fieldsets v1). A fieldset is a curated, named list of field names. It is categorised as a Read tool in the Dynatrace SaaS MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Dynatrace SaaS MCP Server MCP server in PolicyLayer and add a rule for list_fieldsets: 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.
list_fieldsets is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_fieldsets 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.
Set action: deny in the PolicyLayer policy for list_fieldsets. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
list_fieldsets is provided by the Dynatrace SaaS MCP Server MCP server (mnmozi/dynatrace-mcp-saas). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
