Delete a site
AI agents call delete_site to permanently remove resources in Fastly NGWAF MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deletion is an irreversible operation that cannot be undone without restoration from backups. Deleting a site removes infrastructure, configurations, and potentially associated security rules and data. This fits the Destructive category as it causes permanent loss.
From the tool's definition Tool name is 'delete_site' with description 'Delete a site'. The verb 'delete' combined with the scope 'site' indicates irreversible removal of a site resource and all associated data.

Delete a site. It is categorised as a Destructive tool in the Fastly NGWAF MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Fastly NGWAF MCP Server MCP server in PolicyLayer and add a rule for delete_site: 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 Fastly NGWAF MCP Server. Nothing to install.
delete_site 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_site 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 delete_site. 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.
delete_site is provided by the Fastly NGWAF MCP Server MCP server (purpleax/fastlymcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
