🚀 @contextvm/mcp-sdk 1.30.0 — 41% smaller bundles, opt-in validation New patch for our lightweight stdio-focused MCP SDK fork. Two lightweighting wins, zero protocol changes: 📦 Tarball: 2.4 MB → 1.2 MB (−50%) Dropped unreferenced CJS type declarations and source maps that were shipping but never used. 🗜 Consumer bundles: −41% gzip - Client + stdio: 90.4 → 53.1 KB - McpServer + stdio: 97.6 → 60.1 KB The big win: JSON Schema validation (ajv) is now opt-in. Most apps define tools with Zod (validated natively) but never actually validate the JSON Schema they receive over the wire, so they were shipping 37 KB of ajv for nothing. Now ajv only lands in your bundle if you explicitly need it. No breaking protocol changes. McpServer's own tool input/output validation is untouched. Existing apps that relied on default validation just need to pass the validator explicitly to re-enable it. ⚡ Smaller install, smaller apps, same CVM. Alongside this new release, we’ve published a new version of our TypeScript SDK (@contextvm/sdk@0.12.4), which includes this lightweight MCP SDK along with other fixes for open streams

We just got a PR merged into the official MCP Rust SDK! Contributing to upstream feels good man! 😎

Add progress-aware request timeout reset by ContextVM-org · Pull Request #858 · modelcontextprotocol/rust-sdk

We recently released a new version of our TypeScript SDK, v0.12.0! For this version, we forked the official MCP ts-sdk and stripped out all unnecessary dependencies for our project. Many features, such as HTTP transport are useless in ContextVM! Check it out!

This is another brief demo of our latest chat interface at https://contextvm.org/chat. This time, we're connecting to the

WaveFunc Radio

Decentralized internet radio directory and player built on Nostr

metadata server, which gives you useful tools for searching music metadata using the MusicBrainz API. We searched for Nina Simone. Pretty cool, to be honest. This is a great music research tool. If you want to test this, just open https://contextvm.org/s/bb0707242a17a4be881919b3dcfea63f42aacedc3ff898a66be30af195ff32b2 , connect to the server and navigate to the chat route

Also, if you want to chat, share, or clear any doubts, we have a group on Signal and also on Discord. Feel free to join! https://cordn.net/chat/3f5a6278-a38e-4079-840f-4e7523773f38?m=eyJuYW1lIjoiQ29udGV4dFZNIn0%3D

, which aims to bring more clarity and structure to it. We’ve also added documentation for the Rust SDK we recently released. Additionally, remember that we also have Skills to provide all necessary CVM documentation to LLMs. Happy building! 🚀

ContextVM makes it easier to deploy your self-hosted infrastructure. No domains, no OAuth, no port forwarding!

New version of the ts-sdk 0.12.0 🗜 For this version, we forked the official MCP ts-sdk and stripped out all unnecessary dependencies for our project. The official SDK comes with many dependencies related to HTTP transports and other unnecessary features for CVM. We simply removed all that fat to reduce the number of dependencies (from 17 down to just 5). This is especially beneficial for lightweight and web clients. If you want to read more about this fork and what specifically was removed check

New issue of the CVM World. This is the 10th edition. In today's update, we cover the latest news from ContextVM. In particular, we discuss the ongoing effort to expose the functionalities of CVM to other programming ecosystems through bindings in our Rust SDK. We also highlight the recent merge of ephemeral gift wraps in NIP-59, and two powerful additions to our website. Hope you enjoy reading it 🫶 View article →

Agentic Web — The ContextVM World #10

Very pumped to introduce the LLM chat on the contextvm.org website!🚀 https://contextvm.org/chat It's been long overdue, but we've just released the new version of our site, which now includes a chat interface for working with LLMs. This chat connects directly to MCP servers exposed through CVM, making it one of the most comprehensive demos of what CVM enables. You can BYOK or use the free models, though be aware the free models are somewhat unstable, and we highly recommend plugging in your own key or connecting to your local Ollama instance. Any API with an OpenAI-compatible interface will work. You can test public servers or connect to your own private CVM servers. Here are some demos: - Using Wolfram alpha and open meteo to calculate the distance between Madrid and Barcelona, and the weather forecast: - Using Tenor api to find the funniest cat GIFs - Using Relatr to search for Jack and explain why the score This is the agentic web in action. Hope you like this update, and please report any issues if you find them. Huge thanks to @Kushagra for moving this forward.

Ephemeral gift wraps have been merged into the nips repo! 🚀

Nostr Implementation Possibilities. Contribute to nostr-protocol/nips development by creating an account on GitHub.

The implementation of CEP‑15 (Common Tool Schemas) has been merged into the https://contextvm.org website. This allows servers to define their categories and common tool hashes so they can be discovered and grouped accordingly. The result is a marketplace‑style UX where multiple servers can expose the same tools or use the same categories. Server operators can position their services within these common categories or tools, and users can navigate the marketplace to find the services that best suit their needs.

This is very cool. Very innovative way to use ContextVM and it's latest updates 👀 View quoted note →

Yesterday, we finally chose the finalist students from Summer of Bitcoin. These people will spend the whole summer working on the different parts of ContextVM. Here is what they achieved so far: - @Harsh , pushed the implementation of the Rust SDK - @Abhay , who pushed the work on CEP-15** - @Khushvendra , who worked on the TS SDK, CEP-22, and had also the time to do some maintenance work Huge shotout to our interns!🎇🎇

This is an amazing idea, CVM being used to run state machines 🤌 View quoted note →
