I use Grok Business or Enterprise
A team admin adds Welder first. In console.x.ai, open your team, go to Grok Business → Connectors, click + Add Connector, choose Other and enter https://weldergtm.com/mcp. Then connect it on grok.com/connectors.
Grok Bot shows Welder as Disabled by team admin
Your team’s Cursor connector policy blocks it. An admin enables Welder in Teams Marketplace, adds its link to the MCP allowlist if the team uses one, and you restart the app.
Grok Bot’s sign-in didn’t finish
Open Welder in Connect apps and choose Reconnect, or choose Reopen on the card in the chat, to bring the sign-in page back.
Welder says posting more isn’t included
Your first 3 posts are free. After that, posting needs a plan: start your 3-day free trial in the Welder app at weldergtm.com, then ask again. Connecting accounts, uploading and checking a post work either way.
