jason-tan-swe/railway-mcp Destructive Risk 4/5

// WHEN AI AGENTS USE THIS TOOL

AI agents may call tcp_proxy_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. Intercept blocks destructive tools by default and requires explicit human approval before enabling them.

// WHY ENFORCE A POLICY ON TCP_PROXY_DELETE

Without a policy, an AI agent could call tcp_proxy_delete in a loop, permanently destroying resources in Railway MCP Server. There is no undo for destructive operations. Intercept blocks this tool by default and only allows it when a human explicitly approves the action.

// RECOMMENDED POLICY

Destructive tools permanently remove data. Block by default. Only enable with explicit approval workflows.
