ContextVM Concepts

Core concepts, architectural decisions, and common questions about ContextVM.

What is ContextVM?

ContextVM is a protocol that liberates the Model Context Protocol (MCP) by running it over Nostr—a simple, open communication network built on cryptographic, censorship-resistant, and permissionless foundations.

Rather than relying on centralized infrastructure like domains, OAuth, or cloud hosting, ContextVM allows anyone to run or access services using only Nostr and an internet-connected device.

Key Insight: ContextVM operates at the transport layer, meaning existing MCP servers and clients can be used without code changes through the Gateway and Proxy tools.

Why Run MCP Over Nostr?

Running MCP over Nostr eliminates traditional infrastructure barriers:
