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.

Your setup

Diagnosis

Next action

Open Plugins in ChatGPT and add Spun there as a custom MCP server.

In ChatGPT, the custom MCP option is under Plugins, not under Settings.

Menu path

Five business workflows for Spun MCP

How it works

  3. 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.

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.
