Ephemeral Is Better — The ContextVM World #3

Ephemeral Is Better — The ContextVM World #3

GM people, and welcome to the third issue of "The ContextVM World", your biweekly appointment to discover everything you need to know about ContextVM, MCP, Nostr, and all in between!

In today's update we cover ephemeral gift wraps, which have been recently merged into the protocol with CEP-19. This feature introduces an optional convention for CVM servers and clients to exchange encrypted messages using an ephemeral gift wrap kind. We also present the latest release family, v0.6.x.

We also discuss the latest news from the ecosystem, with a new MCP server to query Wolfram Alpha over Nostr, and the new feature being implemented in the CVM protocol, namely CEP-15, for common tools schema, and CEP-17, which provides a way for a server to publish its relay list.

Moreover, we will present a curated list of articles, blog posts, and notes talking about CVM and how it is changing the way we interact with MCP servers.

Finally, we will bring the latest news from the MCP ecosystem, including specification changes and new protocol additions. CVM is built on MCP, which means that we care about providing you up-to-date information from its thriving ecosystem.

Let's start!

News from ContextVM 📰

A list of updates, releases and new cool features.

  • Ephemeral gift wraps are live on CVM: We recently merged
    CEP-19
    proposal, which introduces an optional convention for CVM servers and clients to exchange encrypted
    messages using an ephemeral gift wrap kind. This is a major upgrade that provides more privacy
    in the communication between servers and clients, since it prevents relays to store the events.

    Consequently, we also open a PR in the NIPs
    repository. The proposed modification aims to expand
    NIP-59 to include the convention for
    ephemeral gift wraps.

  • A NIP for CVM: Recently, we opened another PR
    on the NIP repository to formalize CVM as a minimal convention for transporting Model Context
    Protocol (MCP) JSON-RPC messages over Nostr. The proposal is waiting for feedback and reviews from
    other peers.

  • A new major release family for the CVM SDK: With the merging of CEP-19, we released a new major
    version family for the CVM SDK, v0.6.x.

    Notably, v0.6.0 integrates support for ephemeral gift wraps, while maintaing compatibility with previous versions. We also released a patch version, v0.6.1.

    Previously, we released v0.5.0, which
    added a single paymentPolicy hook to make payment consent programmable.

What’s Next for ContextVM? ⏭️

Let’s take a look at the features currently being implemented!

  • CEP-15: This enhancement proposal implements a
    standard for defining and discovering common tool schema. This aims to enable interoperability between
    multiple servers, standardizing tool interfaces that clients can recognize and use consistently. It
    leverages MCP's _meta field, RFC 8785 for deterministic hashing, and
    CEP-6 announcements
    for discovery, creating a marketplace where users can choose between multiple providers implementing the
    same standard tool interface.

  • CEP-17: This enhancement proposal defines
    a relay list mechanism based on NIP-65
    conventions. Servers can publish the list of relays they are connected to using kind 10002 events,
    allowing clients to discover the appropriate relays for establishing connections. This solves the
    current limitation where users must know both a server's public key and its relay URLs to connect.

News from the MCP world 🤖

What is going on in the MCP world?

  • The Skills-over-MCP Interest Group is actively working to provide directions and guidelines
    on the possibility to provide Skills to agents as MCP resources. Contributors are focusing on
    the so-called skills-as-instructors, those that teach an agent how to use MCP tools correctly,
    without executing any code, with the aim to find a common ground to address distribution, portability,
    security and fragmentation. It is possible to find more information in the
    meeting notes.
