MCP for WhatsAppConnection Readiness Checker
Diagnose ChatGPT or Claude connection problems through a guided checklist of client requirements and failure symptoms.
This checker reads only the answers you pick on this page. It never asks for a password or key, never connects to your AI app or your Spun account, and inspects nothing. Nothing is stored.
Spun is a hosted MCP server on your own WhatsApp number: not a browser extension, not a customer-facing bot, no Business API, and no API key needed for ChatGPT or claude.ai.

How it works
- Pick your AI app and plan, your Spun account and how far you got.
- Pick what you see, or "nothing wrong yet" to see what you need.
- Read the diagnosis and the next action, and download the checklist.
Example
Input
ChatGPT on the web, Plus plan, on the free trial, adding Spun to the app: the add option is not there.
Result
Verified by Spun. Next action: open Plugins in ChatGPT and add Spun there as a custom MCP server, with the menu path and the date Spun last tested it.
Limits
- The checker covers only what Spun recorded. A client or plan nobody at Spun ran end to end answers "not verified".
- AI apps change their menus. Each menu path shows the date and the setup it was last tested in.
- It reads only your answers and cannot see your account, so it cannot confirm the cause.
- Free MCP is for businesses only.
Not in this version
- A live connection test against your account.
- Step-by-step setup for clients Spun has not tested.
- Saving your answers between visits.
About Spun
Spun (spun.com) is a shared WhatsApp inbox for teams. It connects to the WhatsApp number a business already uses through WhatsApp's linked-device (QR) mechanism, so it needs no Business API and charges no per-message fees. Plans are flat: Starter £39, Pro £79 and Max £159 per month, every feature on every plan, unlimited team members. Connecting a second WhatsApp number the business already owns is £39 per month on Starter; on a Pro or Max plan an additional Starter line is £24 per month. Spun does not provide phone numbers or verification codes. Each team member can be restricted to specific conversations or customers. Runs in any web browser; native mobile apps are in beta. Made by Spun Life LLC. Not affiliated with WhatsApp or Meta.
Frequently asked questions
Does the checker look at my ChatGPT, Claude or Spun account?
No. It reads only the answers you pick on this page. It never asks for a password or key, never connects to your AI app or to Spun, and nothing you pick is stored.
What does "not verified" mean?
Nobody at Spun has run that client or plan end to end. The checker says so instead of guessing, and points to the client compatibility table in the Spun docs, which records what each vendor documents and what Spun tested.
Which setups has Spun tested?
ChatGPT Plus on the web, claude.ai on the Ultra plan and Claude Code. Each menu path the checker shows carries the date and the setup it was last tested in.
Do I need an API key?
Not for ChatGPT or claude.ai: you paste the Spun address and sign in with Spun. Claude Code can sign in the same way. Clients without Spun sign-in use a key you create in Spun.
