Agent Vault: Grok Bot and Meta Muse shop/login without seeing your card
At a glance
Self Labs’ Agent Vault gives agents mock tokens for checkout and sign-in; real card numbers and passwords never reach the model. Caps, merchant allowlists, and per-purchase approval. Connect Grok Bot via MCP or Meta Muse via custom connector in ~2 minutes (also Claude Code, Hermes, Codex). This workflow is listed under Grok-Bot, Meta-Muse, consumer-agents, payments, HITL, security, MCP, monetize.
Agents / tools
Agent Vault, Grok Bot, Meta Muse, MCP, Claude Code, Hermes, Codex
Ledger’s Agent Intent queue lets background agents (Grok Bot, Muse, Hermes, OpenClaw, Dots) prepare actions—e.g. Grok Bot watches an inbox and drafts an invoice payment—while you review asynchronously and physically confirm on a Ledger signer Secure Screen. Agents never hold signing keys; coding agents can use Agent Stack CLI/skills too.
Marc Lou’s MailCheap exposes Streamable HTTP MCP at https://mailcheap.ai/mcp so ChatGPT, Claude and Grok Bot connect with OAuth (no key to copy); Claude Code, Codex and Cursor use a bearer API key. Agents can draft campaigns, send tests, schedule issues and read stats; schedule/send tools are marked destructive and ask before sending. Open-source / self-host option; pay only for SES-style sends vs beehiiv-class plans.
Skysay’s hosted Streamable HTTP MCP (https://api.skysay.ai/mcp) lets Grok Bot check coverage, request numbers, place approved outbound calls through a hosted voice agent, and send SMS—OAuth/PKCE, separate call vs SMS approval, no local Twilio bridge. Start read-only with account_overview; outside US/CA/UK/MX outbound often needs carrier review first.
xAI gives each account one @mail.grokbot.com inbox for signups and outreach; Shipmail’s MCP connector + webhook lets the same Grok Bot send/receive from your domain and start a Grok automation when new mail arrives—better for customers who distrust mail.grokbot.com.
