What it does
Yes, Grok Build can post to X and 11 more platforms. It reads your repo, writes the post and schedules it, from the terminal.
Setup
Connect Grok Build in two minutes. One command. OAuth opens in your browser on first use.
--transport http is needed: the default is stdio. It goes to ~/.grok/config.toml.
grok mcp add --transport http omnisocials https://mcp.omnisocials.com
Grok opens your browser the first time it calls OmniSocials. Pick your workspaces and click Allow access. Or press i on the server under /mcps.
doctor shows the server, its sign-in and its tools.
grok mcp doctor omnisocials
Headless? Add --header 'Authorization: Bearer ${OMNISOCIALS_API_KEY}' in single quotes, so Grok reads the key from your environment at load time.MCP server docs
