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
- Open Settings → Plugins. Leave the Marketplace tab. Add a custom MCP server.
- URL:
https://mcp.proofinbox.com/mcp. Transport: HTTP / Streamable HTTP. Not stdio. Not localhost. - Authorization token: the workspace_token. If the form wants a header, set
Authorization: Bearer <token>. - 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.

MCP URL
https://mcp.proofinbox.com/mcpInstall 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
balance— confirm the tank. Costs 0.verify_emailwithnot-an-email— invalid syntax, costs 0.- Then a real address. Fresh ZeroBounce checks cost 1. Same address for 30 days is free.
receipts— show the Stripe session id. Do not invent it.
