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.
