# E2B MCP Server (JavaScript)
A Model Context Protocol server for running code in a secure sandbox by [E2B](https://e2b.dev).
## Development
Install dependencies:
```
pnpm install
```
Build the server:
```
pnpm build
```
For development with auto-rebuild:
```
pnpm watch
```
## Installation
To use with Claude Desktop, add the server config:
On MacOS: `~/Library/Application Support/Claude/claude_desktop_config.json`
On Windows: `%APPDATA%/Claude/claude_desktop_config.json`
```json
{
"mcpServers": {
"e2b-server": {
"command": "npx",
"args": ["-y", "@e2b/mcp-server"],
"env": { "E2B_API_KEY": "${e2bApiKey}" }
}
}
}
```
### Debugging
Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the [MCP Inspector](https://github.com/modelcontextprotocol/inspector), which is available as a package script:
```
pnpm inspector
```
The Inspector will provide a URL to access debugging tools in your browser.
