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

{
  "mcpServers": {
    "e2b-mcp-server": {
      "command": "uvx",
      "args": ["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, which is available as a package script:

npx @modelcontextprotocol/inspector \
  uv \
  --directory . \
  run \
  e2b-mcp-server \

The Inspector will provide a URL to access debugging tools in your browser.
