Delete a client from a provider
AI agents call delete_client to permanently remove resources in UseGrant 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 manual intervention or backups. Removing a client from a provider destroys its configuration and access rights permanently. This is more severe than Write (which is reversible) and qualifies as Destructive.
From the tool's definition Tool name is 'delete_client' and description states 'Delete a client from a provider' — uses the verb 'Delete' which indicates irreversible removal of data.
Attacks that exploit this kind of access
Delete a client from a provider. It is categorised as a Destructive tool in the UseGrant MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the UseGrant MCP Server MCP server in PolicyLayer and add a rule for delete_client: 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 UseGrant MCP Server. Nothing to install.
delete_client 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_client 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_client. 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_client is provided by the UseGrant MCP Server MCP server (usegranthq/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
