I converted 10 popular APIs to MCP tools. 7 would let an agent delete your data with zero guardrails.

Stripe. GitHub. Twilio. Slack. Notion. Shopify. Discord. SendGrid. Linear. PagerDuty. None of them ship MCP tool definitions. Every agent developer connecting to these APIs is hand-wiring tools, writing custom auth, and — most dangerously — giving agents full CRUD access with zero risk classification. These are the APIs that run production systems. If you're connecting them to AI agents without knowing which endpoints are destructive, you're one hallucination away from a very bad day. The problem is worse than "no MCP support" I took the public OpenAPI specs for 10 of the most commonly used APIs and converted them to MCP tool definitions. Then I counted how many destructive operations each one exposes — endpoints that delete data, cancel subscriptions, revoke access, or mutate state irreversibly. Here's what I found: API Total Endpoints Safe (GET) Moderate (POST/PATCH) Destructive (DELETE) Official MCP server? Stripe 314 104 163 47 No GitHub 347 189 111 47 Community only Twilio 215 72
