Scalefusion MCP by usefulapi

Use your Scalefusion account from Claude, Cursor, or any MCP client. Read managed devices and groups, and lock, unlock, reboot or move devices. Hosted, no local install: connect with your own credentials.

Live endpoint: https://scalefusion.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

• Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://scalefusion.usefulapi.io/mcp.
• Claude Code: claude mcp add --transport http scalefusion https://scalefusion.usefulapi.io/mcp, then run /mcp to log in.
• VS Code: Add to VS Code.
• Cursor and other clients: add the URL as a remote MCP server:

{
  "mcpServers": {
    "scalefusion": {
      "url": "https://scalefusion.usefulapi.io/mcp"
    }
  }
}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Scalefusion credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/scalefusion/

On first connect you provide your Scalefusion instance region (Global, India, USA or MEA) and your Developer API key (Integrations → Developer API; the account needs the Developer API permission). The server validates them and stores them per user. No keys go in config files.

Pricing

Free	$0	50 tool calls / month
Pro (per user)	$9/mo or $90/yr (2 months free)	10,000 tool calls / month
Pro+ (per user)	$39/mo or $390/yr (2 months free)	100,000 tool calls / month

Each paid plan covers this server only. Ask your AI to run scalefusion_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with scalefusion_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with scalefusion_upgrade before then undoes the cancel. Or write to [email protected].
