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.

Today, we are releasing Relatr v0.1, featuring significant architectural improvements powered by the new Nostr Social Duck library. This update addresses critical scaling challenges and makes running your own trust engine more accessible than ever. We have written an article that delves into the details of this new release and provides other useful resources. We hope you enjoy it as much as we do 💛 View article →

Half of the internet is down today, but Nostr is unaffected. None of the ContextVM ecosystem is down either. Some clients and relays might be down if they are behind Cloudflare, but the protocol itself is not affected. A protocol cannot be taken down; it will find a way. If a client is down, you can switch to another client or, even better, run one locally. Jumble and Nostrudel are already good options for this. If a relay is down, you can go to nostr.watch, pick a new one, and use it to communicate. Even better, you can run your own relay. It can be as easy as running Citrine on your phone and exposing the relay through Tor. No domain is needed; just a couple of apps on your phone and voilà, you can still communicate with your peers. Be your own infra provider. This is why ContextVM. View quoted note →

This is quite cool! Why limit yourself to a single WoT provider when you can use multiple and present the results? The more perspectives, the better. After testing Profilestr, we noticed that Profilestr, Vertex, and Relatr tend to output very similar scores, with only slight variations. This indicates that they are quite solid, even with different approaches to compute the trust scores. Relatr and Vertex can be used without leaving the nostr. Relatr uses CVM, Vertex uses a DVM-like API, Profilestr offers a REST API endpoint, so there's no excuse not to integrate some of these options into your client. Fight spam, protect your users from impersonators, and increase the value. View quoted note →

Thanks to @hzrd149 for contributing Umbrel support for Relatr. Now everyone can deploy their own instance from home without hassle. You just need to add the hzrd's community store by following the instructions here , install Relatr, and you'll be up and running. We are so excited to keep working and improving this to truly democratize WoT and foster a healthier ecosystem 💛 View quoted note →

Do you know about Wavefunc? It's a neat Nostr project that lets you listen to, discover, and share radio stations, and so much more. With ContextVM, Wavefunc can search for music metadata and show you what's currently playing in the radio stations. Plus, you can use their music metadata server on its own. Swing by to see what it's all about. If you want to dive straight into the music metadata server, head over to https://contextvm.org/s/bb0707242a17a4be881919b3dcfea63f42aacedc3ff898a66be30af195ff32b2.

During the process, we removed the persistent database where we were storing some CVM announcements. If you are running a CVM server, please rebroadcast or republish your announcements to our relay. This can be done by simply restarting the server.View quoted note →

Nutoff Reworked: Now Powered by Coco Cashu image We have rebuilt Nutoff from the ground up using Coco Cashu, a new high-level library created by @Egge . Nutoff remains local-first, keeping your nuts off, but now offers complete mint management, true multimint support, seed phrase recovery, and more robust, event-driven operations, all thanks to Coco. Users can expect safer, more reliable wallet behavior and straightforward backup/restore functionality, with all sensitive data kept offline and never leaving your device, using CVM to enables remote invoice, payment, and management flows. How to Get Started: 1. Clone the repository: 2. Open a terminal in the directory and install dependencies, ideally using Bun: `bun install` 3. Run the server: `bun start` 4. You will see a log in the console with your `SERVER PUBLIC KEY: <public-key>` 5. Navigate to contextvm.org/s/<public-key-of-your-wallet> to start using the wallet. With this running, you could use CtxCn to generate a client to your own taste, matching the interface that you like the most. The 'backend' will always remain the same, but you can write any UI/UX on top, like skins, without changing anything in your wallet For more detailed information, refer to the repository's README. Note: Coco-Cashu is currently in alpha. Use it at your own risk. - Coco-Cashu: - Nutoff:

Are you developing a client and want to add search capabilities and WOT scores? You can do it easily by using CtxCn to set up a full Relatr client with minimal hassle. Here’s how: 1. Navigate to your project (it should be in TypeScript) and execute: ```sh npx @contextvm/ctxcn init ``` This command sets up CtxCn in your project. It comes with sensible defaults, so you won't need to configure much. 2. Next, execute: ```sh npx @contextvm/ctxcn add 750682303c9f0ddad75941b49edc9d46e3ed306b9ee3335338a21a3e404c5fa3 ``` This public key corresponds to the default instance of Relatr we are running, which is available at https://relatr.xyz . If you are running your own instance or want to use a different one, simply replace the public key with the appropriate one. That's it! After executing the 'add' command, you will have a fully typed Relatr client in your code, that you can implement out of the box, you own it, and you can modify it to fit your needs. The generated client will also contain comments, making it clear what each method does, whether you or your LLM are reading them. You can search profiles easily with code like: ```ts const searchResults = await relatr.SearchProfiles({ query: "jack" }); ``` This setup allows you to create a web app, a CLI app, or any kind of service in TypeScript. It works in browsers and natively. We hope you enjoy this. The current service we are running is free to use, so if you find this useful, please consider supporting our work. 💛

You can use Relatr to get relevant results from searches containing any word, not just the name of the user you are looking for. For example, here is a quick demo on searching for Nostr-related names. It's still not perfect, as it is still in early development, but we will be sharpening this little by little. View quoted note →
