AI agents may call domain_delete to permanently remove or destroy resources in Railway MCP Server. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. PolicyLayer blocks destructive tools by default and requires explicit human approval before enabling them.
Without a policy, an AI agent could call domain_delete in a loop, permanently destroying resources in Railway MCP Server. There is no undo for destructive operations. PolicyLayer blocks this tool by default and only allows it when a human explicitly approves the action.
Destructive tools permanently remove data. Block by default. Only enable with explicit approval workflows.

It is categorised as a Destructive tool in the Railway MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Railway MCP Server MCP server in PolicyLayer and add a rule for domain_delete: 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 Railway MCP Server. Nothing to install.
domain_delete 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 domain_delete 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 domain_delete. 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.
domain_delete is provided by the Railway MCP Server MCP server (jason-tan-swe/railway-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
