Openterms MCP server

Openterms is a helper that sits between your AI assistant and the actions it takes on your behalf. Before the AI does something, Openterms checks your rules and hands back a signed permission slip, like a receipt, that proves what was agreed. It is handy for anyone who lets an AI spend money or call other services and wants a clear record and a safety net.

What this MCP server does

You ask your AI to do something, like pay a bill or call another service. The AI uses this helper to check your rules first, such as a daily spending cap or a list of allowed actions. If the action passes, Openterms signs a receipt and gives it back. The AI then includes that receipt when it makes the call, and the other service can quickly check it is real. You end up with a clear record of what was allowed, what was blocked, and why.

• “Would a payment of 50 dollars to this vendor be allowed right now”

• “Verify this receipt hash and tell me if it is valid”

What it gives back to you

You get back clear answers in the chat, like whether an action is allowed, a signed receipt, a list of recent receipts, or a summary of past decisions. When something is blocked, you see why. When something goes through, you get the receipt and its details.
