Encrypted Media — The ContextVM World #12

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.

GM people, and welcome to the 12th issue of "The ContextVM World 🌍", your biweekly appointment to discover everything you need to know about ContextVM, MCP, Nostr, and everything in between!
In today's update, we cover the latest news from ContextVM. In particular, we discuss the latest release of the Rust SDK, bringing it closer to feature parity with the TS one.
We also discuss the latest news from the ecosystem. In particular, we cover the latest release of Cordn, which brings encrypted media into the MLS-based chat.
Additionally, we cover the features we are currently working on. Notably, the team is working on integrating the latest developments to CVMI, and reaching feature parity between the Rust and TS SDKs.
Finally, we will share articles, blogs, and posts talking about CVM and the most interesting news from the internet regarding the MCP ecosystem, AI agents, and more!
This will be the last episode of "The ContextVM World 🌍" before summer holidays. We'll be back in September! Enjoy your vacations!
Let's start!
News from ContextVM 📰
A list of updates, releases, and new cool features.
-
Rust SDK: We recently published a new version of our Rust SDK, v0.2.0. This release marks a huge step towards feature parity with the TS SDK, integrating the following CEPs:
- CEP-22 for oversized transfers;
- CEP-41 for open-ended streams;
- CEP-17 for smarter relay resolution;
- CEP-6 for server announcements;
- CEP-23 for profile metadata and social communications.
v0.2.0 also comes with UniFFI bindings, providing support for Python, Swift, Kotlin, and C/C++!
