MCP Gateway v0.2.0 – Streamable HTTP, Infra-as-Code, Dark Mode

[crivetimihai]

🚀 MCP Gateway v0.2.0 – 2025-06-24

This feature-rich release introduces a Streamable HTTP transport, mcpgateway.translate to convert stdio to SSE, infrastructure-as-code assets, and a sleek dark-mode UI, while hardening stability and developer tooling across the board.

✨ Highlights

• 🌊 First-class Streamable HTTP transport – the gateway now speaks MCP’s new default protocol, with stateful-session & auth support. SSE still works, too. Introduced mcpgateway.translate to turn any stdio server into a SSE endpoint.
• 🛠️ Infra-as-Code – drop-in Terraform modules & Ansible roles for cloud installs.
• ⚡ Connection-string exporter – one-click UI / /servers/{id}/connect API for LangChain, Claude Desktop & friends.
• 🌒 Dark-mode Admin UI with a compact version-info panel.
• 🧑‍💻 Developer experience overhaul – 333 green unit tests, tox, pre-commit linters, coverage in CI, Python 3.11+.
• 🏗️ Deployment goodies – Helm charts accept external secrets/Redis, Fly.io guide, Docker-compose switches.
• 🔒 Security & hardening – connection-level time-outs, CVE scans, dependency bumps.
