Spryng MCP by usefulapi

Use your Spryng account from Claude, Cursor, or any MCP client. Check your SMS credits, look up sent messages, and send or cancel scheduled SMS. Hosted, no local install: connect with your own credentials.

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

Connect

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

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

On first connect you provide a Spryng REST API key (Spryng portal → Your Profile → Security). The server validates it 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 spryng_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 spryng_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 spryng_upgrade before then undoes the cancel. Or write to [email protected].
