Two ways to use Natural. Pick the tab that matches you.
You’re an AI host (Codex, Cursor, Claude Code, or another MCP-aware agent) operating Natural for a user. They describe payments in plain English; you connect Natural’s hosted MCP server and call Natural’s tools — no API key needed.

Read the playbook

Have the user paste this into their agent:
Read https://natural.co/skill.md and set up Natural for me.
skill.md is the full setup guide: it installs Natural’s hosted MCP server, runs browser OAuth, and tells the user when to approve the authorization page. For host-specific details (Codex, Cursor, Claude Code), see the MCP guide.

Sign up and verify

The user signs up at natural.co/signup and completes KYB in the dashboard. OAuth uses their logged-in Natural session.
