LG! 🚀

We'll write a spec draft soon so we can move forward with that :)

🌍 New issue of the ContextVM world newsletter 🌍 In today’s update we cover CEP‑17, the latest specification change to the CVM protocol. This change allows MCP servers to announce the relays for establishing connections, making it easier for clients to discover them. We also discuss new CVMI capabilities and other news from the ecosystem, plus demos and a new Rust SDK that is currently being built. Hope you enjoy it!

Just wow! This is seriously cool. I think you did the first integration of chat with CVM tools on the web to date. Really awesome!

Make your MCPs over Nostr, composable, token efficient, easy 🚀 #mcp

Looks dope!

Yes!

Let's keep building! 🚀

Thanks Tim! appreciate your words 💛

The cool part about the demo, ahead of the reduction in token usage compared to building this with the MCP interface, is the progressive disclosure. The LLM didn’t know anything about Earthly, Wolfram, or Relatr, and it discovered tools and usage as needed. No extra tool schemas were loaded unnecessarily, no bloated context window, just organic discovery and usage.

Thanks so much to openSats for this opportunity! We'll keep pushing the boundaries of this new paradigm 💛

We’re thrilled to roll out CVMI CLI 0.2.x, adding two powerful commands: `call` and `discover`. `call` lets you invoke CVM servers straight from the command line, perfect for debugging or plugging into agents. No MCP config or schema loading needed; responses are cleaned to save tokens. Save servers with aliases and run them like `npx cvmi call relatr`. `discover` query relay announcements to list available tools, just run `npx cvmi discover`. Demo: query Earthly and Wolfram for the Eiffel Tower’s address and height Get Sovereign Engineering pubkey using Relatr. These upgrades make CVM servers far easier to use and compose, cut token costs versus MCP, and give developers a simple way to debug, script, or integrate CVM services from the command line.

🚀 CEP-17 is now merged into ContextVM, and it is available in the ts SDK from v0.7.x. https://docs.contextvm.org/spec/ceps/cep-17/ This is a meaningful step forward for resilience. With CEP-17, servers can publish the relay list they use following NIP-65, and clients can resolve connection paths more intelligently: first from explicit configuration, then from relay hints embedded in `nprofile`, and then if nothing is define from relay list discovery. That makes connectivity more robust by default, reduces dependence on central points of failure, and avoids hardcoded relays in normal client setup. It also makes client configuration simpler. In many cases, you can now just pass an `nprofile` string and clients will use its relay hints directly; if those are not available, it can fall back to CEP-17 discovery through NIP-65 relay-list metadata. The reference implementation is already in the SDK, the docs and skills have been updated, and contextvm.org now surfaces these new `nprofile` identifiers as well. Small change in surface, big improvement in how reliably clients can find and reach servers across a more sovereign network 🚀
