fly-mcp-gateway

Always-on Streamable HTTP MCP gateway for Fly.io. Use this instead of a flaky Cloudflare Tunnel (mcp.oceanways.online).

• Endpoint: https://<your-app>.fly.dev/mcp

• Health: https://<your-app>.fly.dev/health

• Optional auth: Authorization: Bearer <MCP_API_TOKEN>

Deploy (once)

# 1. Install flyctl — https://fly.io/docs/hands-on/install-flyctl/
fly auth login

# 2. Clone
git clone https://github.com/hush759/fly-mcp-gateway.git
cd fly-mcp-gateway

# 3. Launch (creates app + deploys)
fly launch --copy-config --yes

# 4. Set a secret token (recommended)
fly secrets set MCP_API_TOKEN="$(openssl rand -hex 24)"

# 5. Redeploy if needed
fly deploy

Pick a unique app name when prompted (e.g. clipboardh-mcp or hush759-mcp).

Point Grok / Cursor at it

Replace the old oceanways URL with:

{
  "mcpServers": {
    "fly-gateway": {
      "type": "streamable-http",
      "url": "https://YOUR-APP.fly.dev/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_TOKEN"
      }
    }
  }
}

Free plan notes

fly.toml sets:

• auto_stop_machines = "off"

• min_machines_running = 1

That keeps one machine running so MCP does not cold-start. Free allowance is limited — watch Fly billing so you do not exceed free credits.

Add tools

Edit server.js and register more server.tool(...) handlers, then:

git add -A && git commit -m "feat: more tools" && git push
fly deploy

Local test

npm install
MCP_API_TOKEN=dev node server.js
# curl http://localhost:8080/health
