AI That Drafts — You Decide What Goes Out
Drafts from a description, and an API an assistant can hold — both of which stop short of sending.
Connect AI Agents Safely with Official MCP
Claude, ChatGPT, and Gemini connect natively via our streamable HTTP Model Context Protocol endpoint. The assistant reads, drafts and asks; a request goes ahead only once a signed-in person, or the workspace owner’s capped rule for a connection the owner put in Auto approves it.

AI Studio
Invoice template designer
Describe the layout; the preview is drawn by the real renderer. A draft until a person publishes it.

Emits colour values, never CSS, and every one is checked for contrast in both themes before it can be published.
Server verifiedai-pay-pageAssistive copy
Reminder text, line descriptions and payment-plan explanations. Plain text only — tags and links are refused.

API and assistants
REST API and API keys
Every operation under one OpenAPI document, scoped per key.
Server verifiedapi-restHosted MCP server
Connect an AI assistant to your billing. It reads, drafts, records and asks: in Ask, the default, a signed-in person approves each request; Plan is a dry run; in Auto, which only the owner can switch on with a second factor, on a plan with auto-approve rules, the owner’s capped rule approves what it covers. For a connected assistant, refunds, voids, card or bank entry and the other never-auto requests still wait for a person.
Server verifiedapi-mcpAuto-approve rules
The owner writes capped rules — kind, amount, count a day — and a matching action runs at once, with the connection as actor. For a connected assistant, refunds, voids, card or bank entry and the other never-auto requests still wait for a person; the built-in Agent, in Auto on its own person’s grant, may run some of them under the owner’s rule.
Server verifiedagent-autoOutbound webhooks
HMAC-signed, retried and dead-lettered, with the destination re-resolved on every delivery.
Server verifiedapi-webhooksApprovals inbox
What an assistant asks for waits here, out of its reach, for a person to approve it, unless the connection is in Auto and the owner’s capped rule covers the request.
