SINT Protocol MCP server

SINT Protocol is a security layer that sits between your AI and the tools it wants to use. Before your AI does something, SINT checks whether it is allowed, and if the action is risky it asks a human first. It is handy for teams who let AI touch real things like smart home devices, robots, or systems where mistakes cost money.

What this MCP server does

You ask your AI to do something, like unlock a door or run a tool. Your AI sends that request through this MCP server. The server passes it to SINT's Policy Gateway, which checks the request against rules, permissions, and limits. SINT then answers with allow, deny, or escalate to a human. Every decision can be written to a tamper-evident log so you can see what happened later.

What you can do with it

• Check whether a tool call is allowed before it runs
• Route risky actions to a human for approval
• Apply limits like budget, rate, or physical constraints
• Revoke an agent's permission in real time
• Record every decision in a hash-chained audit log
• Scan tools for risk before you use them
• Govern smart home actions like locks and alarms

Try asking your AI

• “Unlock the front door”
• “Turn off the living room lights”
• “Run this tool but ask me first if it looks risky”
• “Show me the audit log for the last hour”

What it gives back to you

You get a clear answer back in the chat: allowed, denied, or waiting for your approval. If the action ran, you may also see a receipt that proves what happened. For audit requests, you get a list of past decisions with timestamps.

Who it's for

Teams and developers who let AI control real-world systems like smart homes, robots, or industrial equipment, and anyone who needs a record of what the AI did.
