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.
Awesome project! Napplets are already quite powerful. Giving them backends through CVM for multiplayer capabilities, leaderboards, and more, makes them even more powerful.

Continuing with our community appreciation round, Cordn is one of the apps at the forefront of what we’re building at ContextVM. This is one of the most exciting projects related to sovereign and private communications in the space as well.
What makes Cordn stand out at the edge of what’s being built at CVM is that it was one of the first real apps to use our Open Streams (CEP-41) feature, which allows them to directly stream new messages to users, so they receive them in real time. They’ve helped us catch edge cases and issues, and now the CVM implementation of Open Streams is more robust in the TypeScript and Rust SDKs. Thanks!
Aside from that, they’re also one of the first consumers of the UniFFI bindings we recently released from our Rust SDK. They built their app with native Kotlin modules for their notification service using the bindings from our Rust SDK, and it’s working flawlessly so far.
Thanks to the @Besao and @Cordn App teams for pushing forward the boundaries of what’s possible in this space!

Earthly is one of the coolest apps in Nostr, pushing the boundaries of what you can do with today’s technology, seriously underrated. It was one of the early apps to integrate with ContextVM for their APIs and AI integration, letting you do crazy stuff like drawing geometry on a map, tracing routes, and much more. But that’s not all! They released an Android app that runs a Blossom server and a relay 🤯 for fully offline operations. And if that wasn’t enough, they’ve also integrated with Cordn for groups and private communications 🤯🤯🤯

This is a very cool concept from @karliatto so many cool possibilities

@npub18px9...p2py is one of the Summer of Bitcoin students working with us at ContextVM. He wrote this great article about his experience during this period. Give it a read! 😊

Escaping Rented Land: Routing Agentic Computation Over Nostr
I’ve been spending a lot of time lately digging deep into decentralized systems, and recently, a realization hit me pretty hard: even on the mode...
The ContextVM website now has agent-native payments, building on the recently updated CEP-8. 🦾🤖
The CEP-8 update brought explicit gating to the payment lifecycle, the same approach that other protocols like 402 or mpp are following, and that small change is what makes agents able to pay natively. That's the building block for an economy where agents pay agents and tools over Nostr.
To make that loop real, the ContextVM site got a built-in Lightning wallet. Connect it once with a NWC string and it is ready across the app. You can check your balance, generate a QR to receive, or paste a bolt11 invoice to pay.
The wallet also shows up exactly where it counts: any Lightning payment card gets a Pay button, and after paying, you get a Retry call button that resumes the tool.
Agents that can spend and earn over Lightning, native to Nostr. Permissionless, seamless.
Try it:
#Nostr #Lightning #Bitcoin #AI #Agents #NIP47

ContextVM
Decentralized transport for MCP servers on Nostr. No domains, no OAuth, no port forwarding—just keys, relays, and optional Lightning payments.
Very pumped to introduce the LLM chat on the contextvm.org website!🚀
https://contextvm.org/chat
It's been long overdue, but we've just released the new version of our site, which now includes a chat interface for working with LLMs. This chat connects directly to MCP servers exposed through CVM, making it one of the most comprehensive demos of what CVM enables.
You can BYOK or use the free models, though be aware the free models are somewhat unstable, and we highly recommend plugging in your own key or connecting to your local Ollama instance. Any API with an OpenAI-compatible interface will work.
You can test public servers or connect to your own private CVM servers.
Here are some demos:
- Using Wolfram alpha and open meteo to calculate the distance between Madrid and Barcelona, and the weather forecast:
- Using Tenor api to find the funniest cat GIFs
- Using Relatr to search for Jack and explain why the score
This is the agentic web in action. Hope you like this update, and please report any issues if you find them.
Huge thanks to @npub10hxj...wtt6 for moving this forward.
Thanks so much to openSats for this opportunity! We'll keep pushing the boundaries of this new paradigm 💛
