Frequently asked questions

What is the E2B MCP server?

The E2B MCP server is an Developer Tools Model Context Protocol server that lets Claude Code, Cursor, Windsurf, VS Code with Copilot, and other MCP-compatible AI agents run code in secure cloud sandboxes hosted by E2B. It exposes E2B's capabilities as tools the AI can call directly from your editor or CLI.

How do I install E2B MCP with Claude Code?

The fastest way is the MCPizy CLI: run `mcpizy install e2b` and MCPizy will add the server to your `.claude.json` automatically. You can also install it manually by adding an entry under `mcpServers` in `.claude.json` with the command `npx -y @e2b/mcp-server` and restarting Claude Code.

Is E2B MCP free?

Yes. The E2B MCP server is free and open source (see the GitHub repository linked on this page). You may still need a E2B account or API key to connect the server to the underlying service, but the MCP layer itself has no MCPizy subscription cost.

Does E2B MCP work with Cursor and Windsurf?

Yes. Any MCP-compatible client works — including Claude Code, Claude Desktop, Cursor (via `.cursor/mcp.json`), Windsurf, VS Code with Copilot Chat, and custom agents built on the MCP SDK. The same install command targets all of them; only the config file path differs.

What can I do with E2B MCP?

Once installed, your AI agent can run code in secure cloud sandboxes hosted by E2B directly inside your conversation. Typical use cases include asking Claude Code or Cursor to run E2B operations, inspect results, chain E2B with other MCP servers (see our Workflow Recipes), and automate repetitive developer tools tasks without leaving your editor.
