spryng_get_messageReturn one SMS message by its Spryng id (UUID), including its status when available.
spryng_list_subaccountsList the subaccounts of this Spryng account. Filter by active state or a username/email search string.
spryng_send_messageSend one SMS to up to 50 recipients. Spends credits and cannot be undone once sent. Use scheduled_at to send later (cancel with spryng_cancel_message before it is sent).
spryng_cancel_messageCancel a scheduled message before Spryng sends it. A message already sent cannot be cancelled.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 4 of 4 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed 2 days ago, and the latest version (1.6.2) reached the registry 2 days ago.
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).

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.

read tools are read-only; write tools mutate data (clients should confirm them); meta tools report usage, manage your subscription or send a feature request.
| 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 support@usefulapi.io.
