Play Systems MCP by usefulapi

Use your Play Systems account from Claude, Cursor, or any MCP client. Read-only access to e-invoices and their payments, hosting packages, domains, DNS and web usage. Hosted, no local install: connect with your own credentials.

Live endpoint: https://play-systems-api.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

• Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://play-systems-api.usefulapi.io/mcp.
• Claude Code: claude mcp add --transport http play-systems-api https://play-systems-api.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": {
    "play-systems-api": {
      "url": "https://play-systems-api.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 Play Systems credentials.

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

On first connect you provide your Play Systems API key and your Issuer VAT number (9 digits). Play Systems shows the key once, when it is created; ask Play Systems for a new key if you lost it. The server uses the VAT number once to check the key and does not store it. The server validates the key and stores it per user. No keys go in config files.

Pricing

Plan	Price	Limit
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 playsystemsapi_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 playsystemsapi_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 playsystemsapi_upgrade before then undoes the cancel. Or write to [email protected].
