Grok Bot

Connect Proof Inbox

Grok Bot only talks to a public Streamable HTTP MCP server. Point it at https://mcp.proofinbox.com/mcp. Auth is the workspace token from checkout — not a Stripe key. Field-by-field form: /grok-bot.

No token in this URL. Buy credits to create one, or open /connect?workspace=ws_live_… after checkout.

In Grok Bot

  1. Open Settings → Plugins. Leave the Marketplace tab. Add a custom MCP server.
  2. URL: https://mcp.proofinbox.com/mcp. Transport: HTTP / Streamable HTTP. Not stdio. Not localhost.
  3. Authorization token: the workspace_token. If the form wants a header, set Authorization: Bearer <token>.
  4. Paste the install prompt below into the bot instructions so it reuses this workspace and does not invent results.

grok.com/connectors is Grok chat, not Grok Bot. grok mcp add is Grok Build. Exact Grok Bot fields live on /grok-bot.

Install prompt

Use MCP https://mcp.proofinbox.com/mcp.
Pass workspace_token on every tool call, or Authorization: Bearer <workspace_token>.
Tools: balance, verify_email, receipts.
If a tool returns payment_required, open checkout_url, complete Link checkout, wait for credits, retry.
Save workspace_token and reuse it. Never invent a new one.
Never invent verify results. If status is unknown, say unknown.
After a pack purchase, call receipts and show me the Stripe session id.

First calls

  1. balance — confirm the tank. Costs 0.
  2. verify_email with not-an-email — invalid syntax, costs 0.
  3. Then a real address. Fresh ZeroBounce checks cost 1. Same address for 30 days is free.
  4. receipts — show the Stripe session id. Do not invent it.
