Run code in secure sandboxes hosted by E2B

Kilntainers is an MCP server that gives LLM agents isolated Linux sandboxes for executing shell commands. 🧰 Multiple backends: Containers (Docker, Podman), cloud-hosted micro-VMs (Modal, E2B), and WebAssembly sandboxes (WASM BusyBox, or any WASM module). 🏝️ Isolated per agent: Every agent gets its own dedicated sandbox — no shared state, no cross-contamination. 🧹 Ephemeral: Sandboxes live for the duration of the MCP session, then are shut down and cleaned up automatically. 🔒 Secure by design: The agent communicates with the sandbox over MCP — it doesn’t run inside it. No agent API keys, code, or prompts are exposed to the sandbox. 🔌 Simple MCP interface: A single MCP tool, sandbox_exec, lets your agent run any Linux command. 📈 Scalable: Scale from a few agents on your laptop to thousands running in parallel in the cloud.

Support connecting E2B via MCP, with custom server and client, without the need for tools like the Claude app, Cursor, etc.

Execute one-off or scheduled tasks within a virtual computer that can spin up a real browser, a full coding agent, an email inbox and more. OpenHelm unlocks the ability for your agent to carry out all sorts of tasks, such as: • Deep research on a topic • Emailing + handling responses • Coding work • Updating files What makes OpenHelm the best solution for this: • Underpinned by a powerful AI that monitors work and ensures goals are actually achieved • Browser is SUPER stealthy, meaning it can access more of the web than other bots • Work is managed by a powerful agentic system, facilitating multi-step flows For performing complex, one-off or recurring work, OpenHelm provides a secure, remote environment to make it all possible.
