Aval MCP

Aval is a human-in-the-loop MCP server that allows AI agents to pause before performing sensitive actions like payments, sending emails, or deleting data. It sends a question with options to the user's phone, Telegram, or email, waiting for a tap to proceed or refuse, ensuring human oversight for critical decisions.

Endpoint and access

OAuth sign-in: the first time you connect, your client opens the vendor's own authorization prompt in a browser.
