Disable the currently registered webhook, stopping all incoming Viber event callbacks. Use when decommissioning the bot or before switching endpoints via set_webhook. No parameters required.
AI agents call remove_webhook to permanently remove resources in Viber — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Removing a webhook irreversibly stops all incoming event callbacks to the bot. While the webhook can technically be re-registered, this action cuts off all bot functionality immediately and can disrupt live services. It is an irreversible action in the moment (all in-flight events are lost) and matches the Destructive category due to its potentially severe operational impact with no undo path for missed events.

Attacks that exploit this kind of access
Disable the currently registered webhook, stopping all incoming Viber event callbacks. Use when decommissioning the bot or before switching endpoints via set_webhook. No parameters required. It is categorised as a Destructive tool in the Viber MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Viber MCP server in PolicyLayer and add a rule for remove_webhook: 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 Viber. Nothing to install.
remove_webhook 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 remove_webhook 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 remove_webhook. 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.
remove_webhook is provided by the Viber MCP server (serhiizghama/viber-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
