@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.

In just one week since the start of the Summer of Bitcoin program, interns working on ContextVM have already opened and merged several PRs in different CVM project.

Our students are really nailing it! 🫶

That's sweet. Love listening to Reladder updates. 😁

Very excited to announce this! 🚀
Let a thousand algorithms bloom. You can now write Relatr plugins as Nostr events, install them from Relatr.net, and much more. If you care about the WoT, this is huge!

ContextVM TS SDK 0.8.0 is live, with CEP‑22 oversized‑payload transfer.

Large payload delivery over Nostr relays is now much more robust. We even stress‑tested it by pushing a 1.5 MB image over regular relays, partly to check robustness and partly for fun :) It worked, but keep in mind that this is not a general‑purpose file transfer protocol

If you run a server or client on the TS SDK, update to 0.8.0. The CVMI CLI was also bumped to include it.

We keep pushing boundaries 🚀

If you are curious about the underlying specification you can read it here: https://docs.contextvm.org/spec/ceps/cep-22/

Communications over the internet has been centralizing more and more since its very beginning, choked by permissioned control points. The risk we foresee is that the agentic web can fall in the same trap.

ContextVM actively breaks this monopoly by routing the Model Context Protocol (MCP) over Nostr's decentralized relay network, leveraging censorship-resistant public keys that no single entity can shut down or revoke.

Introducing CEP‑22 (WIP). This new spec adds a simple way to transport ContextVM messages that exceed the relay size limit. It proposes fragmenting a single payload into chunks across multiple events and reassembling it once the receiver has collected all the chunks. The design stays narrow, just enough to handle larger tool results while preserving the current workflow.
See the draft spec: https://github.com/ContextVM/contextvm-docs/blob/feat/larger-than-relays/src/content/docs/spec/ceps/cep-22.md

"Exciting to see ContextVM investing in open-source mentorship—projects like Summer of Bitcoin need strong guidance, especially with rising threats. Speaking of threats, I just read about the drone attack in Saudi Arabia disrupting air traffic, including high-profile departures. Security risks are...

We bring amazing news! ContextVM has been invited to participate in the Summer of Bitcoin program. https://www.summerofbitcoin.org/

This is a global, online summer internship program focused on introducing university students to Bitcoin, Nostr, and open-source development and design. We’re very glad to have been chosen as mentors.

We’d also be grateful to hear your project ideas for a student to work on for ContextVM during the summer. Please share any you have. What would you like to see in ContextVM?

Students who spend a summer building on open, self-sovereign protocols develop a different intuition than ones who built on platforms with a ToS. Summer of Bitcoin has been quietly compounding that pipeline for years.

Setting up an MCP server to be used by AI agents requires a lot of skills, managing domains, OAuth, port forwarding.

ContextVM changes the game, reducing the burden for running a remote MCP server!
