A smart MCP server that integrates E2B for code execution in the cloud
Smart E2b MCP server exists for a simple reason — assistants are far more useful when they can act on Smart E2b directly instead of describing what you should do. A smart MCP server that integrates E2B for code execution in the cloud.
Un serveur MCP (Model Context Protocol) qui intègre E2B pour exécuter du code dans des environnements sandbox sécurisés dans le cloud, spécialement conçu pour fonctionner avec Claude AI Desktop.
Once Smart E2b is connected, these are the calls the assistant has available:
executeJavaScript — Exécute du code JavaScript dans un sandbox cloudexecutePython — Exécute du code Python dans un sandbox clouduploadFile — Téléverse un fichier dans le sandboxlistFiles — Liste les fichiers dans un répertoire du sandboxreadFile — Lit le contenu d'un fichier dans le sandboxExemples — Voici quelques exemples d'utilisation avec Claude AI Desktop :You will need one environment variable: E2B_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Installation goes through your MCP client rather than a global install: point it at @smithery/cli on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Smart E2b's toolset — executeJavaScript, executePython, uploadFile and 3 more — is a fair guide to whether it matches your workflow. It is maintained by Leghis; worth a glance at recent repository activity before you build anything load-bearing on it.
