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.
