skgate MCP server

skgate

Serve your MCP servers and REST APIs from one OAuth-protected gateway. Also proxy your SI providers behind one address with model aliases, and use your Grok subscription as an OpenAI-compatible API, no API key needed.

Any MCP server. skgate can run them for you, so you do not need one container per server.

Name Origin

skgate /ɛsˈkɑːɡeɪt/ (ess-KAH-gate)

"sk" is how a lot of SI API keys start, and "gate" is for gateway. Not a great name, but it's ours.

The plane in the logo is an inside joke. The public wouldn't understand it, and I'm not about to explain it. Sorry.

Quality

Is it good?

Yes

Quick start

You need an OIDC provider with a confidential client for skgate. Admin login is OIDC only. Trying it on one machine? docs/quickstart.md runs skgate with a bundled provider and no accounts.

# docker-compose.yml
services:
  skgate:
    container_name: skgate
    image: ghcr.io/helv-io/skgate:latest
    restart: always
    ports:
      - 8080:8080
    environment:
      - PUBLIC_URL=https://skgate.example.com
      - OIDC_ISSUER=https://auth.example.com
      - OIDC_CLIENT_ID=skgate
      - OIDC_CLIENT_SECRET=change-me
    volumes:
      - ./data:/data
    healthcheck:
      test: ["CMD", "/skgate", "healthcheck"]
      interval: 30s
      timeout: 5s
      retries: 3

1. docker compose up -d
2. Open https://skgate.example.com/admin and sign in through your OIDC provider.
3. mcp upstreams > Add upstream: a remote MCP server, or a GitHub repository, npm package, or PyPI package that skgate runs for you (see Add an MCP server with Suggest configuration).
4. Point your MCP client at https://skgate.example.com/mcp or the site root for every included upstream, or at https://skgate.example.com/mcp/ for one upstream. Sign in when it asks.

Image tags:

• latest: proxy + managed MCP servers. Bundles Node.js (npx), pnpm, Bun (bunx), Deno, Python (uv, uvx), Go, .NET and git.
• slim: proxy only

To upgrade, back up ./data, then docker compose pull && docker compose up -d.

Proxy your SI providers

skgate is also an OpenAI-compatible API in front of your SI providers. Point your apps at one address; switch the provider behind them without changing the apps. User-defined model aliases give your apps a stable model name of your choosing.

Grok can use subscription sign-in with no API key. Other providers use that provider's API key (OpenAI, Anthropic, Gemini, Mistral, DeepSeek, Groq, OpenRouter, Ollama, LM Studio, and any OpenAI-compatible endpoint).

1. status > Grok > Sign in: open the shown address, enter the code, approve. skgate keeps the sign-in fresh.
2. keys > enter a name > Create key. Copy the sk-... key; it is shown once.
3. Use it: base URL https://skgate.example.com/v1, API key sk-... (see Examples).

• These base URLs all reach the same API: /v1, /api, /api/v1, and the bare host. Use whichever form your client expects.

1. Other providers: status > Add provider, pick one and enter its API key. Type the provider's address in any form; skgate finds the one that works.
