What deleteWebhook does on Spline MCP Server
AI agents call deleteWebhook to permanently remove resources in Spline MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why deleteWebhook is rated Critical
The 'delete' prefix unambiguously signals a Destructive action—removal of a webhook configuration that cannot be undone by the tool itself. While the blast radius is moderate (deleting webhooks affects integrations but not primary design data), it remains irreversible. The lack of description slightly reduces confidence but does not change the category, as the name is explicit.
From the tool's definition Tool name 'deleteWebhook' uses the verb 'delete', which indicates irreversible removal of data. No description provided, but the name clearly denotes a destructive operation.
Attacks that exploit this kind of access
The rule that runs deleteWebhook safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Spline MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For deleteWebhook, this is the rule to start with:
deleteWebhook is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Spline MCP Server, apply this rule, and every deleteWebhook call is checked against it from then on.
