Installable straight from Grok Build's built-in /marketplace.
B2BLeads is submitted to the official xAI plugin marketplace (xai-org/plugin-marketplace) — browse to it with /marketplace inside Grok Build and install with a keypress, no separate download or manual config.
Like every third-party entry in that marketplace, the submission is pinned to an exact, reviewed commit of the plugin repository, so Grok Build always runs code that's been through xAI's review, not a moving branch.
Once installed, Grok gets search_leads, list_industries, and find_email, authenticated through the same OAuth 2.1 flow as the other remote clients — so a Grok Build session can go from a plain-language request straight to a list of real companies.
