Nobulex MCP server

Nobulex is a tool that keeps a signed record of what an AI agent does, so you can check later that the record was not changed. It is handy for people who let an AI take actions and want a simple trail of what happened. You do not need to be a programmer to understand the idea, but setting it up does involve running some commands.

What this MCP server does

You ask your AI to do something, like send an email or process a payment. The AI passes that action to this helper. The helper checks the action against rules you set, like permit read or forbid delete. If the action is allowed, it runs and a signed receipt is created. If the action breaks a rule, it is blocked before it runs. Over time, the receipts build a trust score for the agent.

What you can do with it

• Record each AI action as a signed receipt
• Block actions that break rules you set
• Build a trust score for an AI agent over time
• Verify that a record of actions has not been changed
• Check whether an agent is allowed to do something
• Export an audit trail as a file

Try asking your AI

• “Record this action as a receipt and tell me if it was allowed”
• “Check the trust score for my agent”
• “Show me the audit trail for the last ten actions”
• “Verify that this receipt file has not been tampered with”

What it gives back to you

You get back a receipt for each action, with a note saying whether it was allowed or denied. You can also get the agent's current trust score, which is a number that grows as the agent behaves well. If you ask for an audit trail, you get a file with the full history. The chat shows these as short text answers or a file you can save.
