AI agents call deleteGraphTool to permanently remove resources in mcpGraph — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool deletes configuration or definitions from the mcpGraph system. Deletion is irreversible and prevents recovery of the deleted tool. The blast radius depends on whether the tool is actively in use—removal could break dependent workflows or orchestrations. This is Destructive rather than Write because the operation cannot be undone (no undo/rollback mechanism described).
From the tool's definition Tool name 'deleteGraphTool' combined with description 'Delete a tool from the mcpGraph' explicitly performs an irreversible deletion operation.
Documented attack patterns abuse exactly the kind of access deleteGraphTool gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and mcpGraph, and nothing reaches the server without passing your rules. This is the rule we recommend for deleteGraphTool:
{
"version": "1",
"default": "deny",
"hide": [
"deleteGraphTool"
]
}deleteGraphTool disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Delete a tool from the mcpGraph. It is categorised as a Destructive tool in the mcpGraph MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the mcpGraph MCP server in PolicyLayer and add a rule for deleteGraphTool: 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 mcpGraph. Nothing to install.
deleteGraphTool 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 deleteGraphTool 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 deleteGraphTool. 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.
deleteGraphTool is provided by the mcpGraph MCP server (teamsparkai/mcpgraph). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from mcpGraph, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
