Submit a plugin or MCP to the Grok Bot Marketplace
At a glance
Official xAI form lets builders list a remote MCP server or public GitHub plugin for Grok Bot and Cursor (Grok chat listed as coming soon). Need org handle, 1:1 logo, description, testing instructions, local+in-app test confirmation; free-to-users publisher terms; review follows by email. This workflow is listed under Grok-Bot, marketplace, MCP, plugins, devtools, monetize.
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).
Official xAI guide: Share as Template packages instructions, skills, routines and first-party plugins into an anonymized blueprint (team or public link)—no secrets, custom code, MCP servers, logins or history. Installers get a fresh bot that must re-approve plugins; encode setup steps for API keys and custom MCP so others can reproduce the workflow.
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.
