We're partnering with @Docker to bring 200+ MCPs right in @e2b sandboxes through the Docker's MCP Catalog. Docker is already used by over 20M developers. We're extremely excited we can bring secure and isolated agentic runtime - E2B Sandbox - to them. e2b.dev/docs/mcp
Docker is excited to partner with E2B, a platform for running AI-generated code in secure cloud sandboxes. Docker + E2B now gives AI agents access to real tools (GitHub, Perplexity, Browserbase) in secure sandboxes via the MCP Catalog.
Webhooks for sandbox lifecycle API
We've shipped webhook management in the dashboard 🎉 Teams can now set up webhooks to receive real-time notifications when sandbox lifecycle events occur: 🔸 Create and manage webhooks with custom URLs and event subscriptions 🔸Subscribe to 5 lifecycle events: created, paused, resumed, updated, killed 🔸Custom signature secrets (>32 chars) for secure webhook verification 🔸Zero-downtime secret rotation with step-by-step safe rotation guide 🔸Edit webhooks to update name, URL, or event subscriptions 🔸Visual table showing all configured webhooks with events and metadata

Meet Agent Bake-Off: blind side by side tests for coding agents like Claude Code, @cursor_ai , @AmpCode , @FactoryAI , Codex, & more. We've been building the largest real world benchmarks for coding agents, and we're excited share an early preview of our open community tooling.

turns out there's a lot of alpha in doing things really well.

Three lines of code and you have your own @bunjavascript sandbox on @e2b Step 1: use e2b Step 2: create bun based sandbox Step 3: let AI agents run JS with bun Step 4: profit easy

I want to write something about E2B tech internals, but can’t decide where to start.

Spent the last few days stepping out of my comfort zone to build a tool inspired by @e2b, which lets you create sandbox environments. I built a similar system using Firecracker — with my own twist. Docs: coherent-bramble-573.notion.…

your engineer sends you this, what are you going to do?

Genuinely cool to see everyone getting sandboxes now When we started in 2023 no one got it. We spent a year educating developers. Investors were telling me it makes no sense and it’s basically a lambda function. Now, it’s a no-brainer and we’re just starting 🚀

Alex is right
2023 was the year of the chatbot. 2024 was the year of RAG and finetuning. 2025 has been the year of MCP and tool use. 2026 will be the year of the computer environment and filesystem.

Launched just last week, the @e2b + Docker MCP Gateway partnership is already making its way into the classroom - now featured in a deeplearning.ai course. This is a great way to dig in, learn how secure AI agents actually work, and stay ahead of the curve. Seeing it go from launch to learning material this fast shows just how quickly secure, real-world AI tooling is becoming the new standard: e2b.dev/docs/mcp

I genuinely think @co_valenta's and my advantage is to go 10x more intense, willing to sacrifice 10x more, and keep going 10x longer than the next guy. When we started, we new no one. No SF network to tap. No pedigree. No outside money. No experience working at Stripes and Airbnbs. Not based in the US. No US school. And we're willing to risk it all. We'll just build all of it again.

The E2B & Docker MCPs gateway was launched on Thursday and it's already appearing in a deeplearning.ai course <3

Exciting launch from @e2b! MCP as code, made easy, out of the box. Tutorial for using E2B’s code MCP feature with @GroqInc in <60 lines of code as reply below!

Proud to partner with E2B and Docker as an early tester. We are using the MCPs in the sandbox for powering our AI agents - giving users access to hundreds of specialized tools and the ability to deploy any GitHub-based MCP server to extend our agents instantly. This launch changes a lot for AI platforms!

or @exaailabs, giving AI agents ability to search through the internet right from the sandbox in lightspeed. github.com/e2b-dev/e2b-cookb…
