Lessons and Innovations from CVM at SovEng 5

ContextVM
ContextVM is a decentralized protocol that enables Model Context Protocol (MCP) servers and clients to communicate over the Nostr network. It uses Nostr as a secure, distributed transport layer—leveraging cryptographic keys for identity, decentralized discovery, and Bitcoin-powered micropayments. Rather than relying on centralized infrastructure like domains, OAuth, or cloud hosting, ContextVM allows anyone to run or access services using only Nostr and a internet-connected device. It transforms any computational service into a discoverable, accessible, and monetizable resource—while preserving privacy, security, and user sovereignty.

Here is a short demo video walking through the ContextVM ecosystem. In it, we demonstrate some fundamental concepts, including creating a Cashu wallet, wrapping its API in an MCP server, and exposing it as a ContextVM so it can be used from Nostr. We also introduce a new tool we are working on CtxCn, which allows you to easily integrate any CVM server into any TypeScript project. Additionally, we show how to create a demo website from a single prompt that just works. This is just a quick overview of what is possible with ContextVM. More details about what we have been building during #sovEng 5 will be available soon. On this video:
