E2B MCP Server

An MCP server that exposes the E2B Sandbox API as Model Context Protocol tools.

Features

The server currently provides tools for:

• Sandboxes — create, list, connect, pause, delete, manage timeouts, refresh, and retrieve logs.

• Templates — create, list, inspect, update, delete, start builds, retrieve build status, and retrieve build logs.

• Filesystem — list directories, create directories, move and remove files, inspect file metadata, read files, upload files, and manage file watchers.

• Processes — run commands, list processes, send signals, interact with stdin, and resize PTYs.

Deprecated E2B API endpoints and snapshot-related functionality have been removed from the project.
