      "summary": "Initial evaluation. E2B delivers strong agent-native infrastructure with clean API key auth, comprehensive documentation including llms.txt, extensive SDK support, an MCP gateway, lifecycle webhooks, and open-source distribution. The main gaps are human-gated onboarding, lack of a standalone MCP server for the E2B API itself, and no formally published error-code taxonomy."
