Working with her in the terminal

Grok Build is xAI’s coding agent. It lives in the terminal, runs commands, and speaks MCP. It is not Grok chat on grok.com, iOS or Android, and it is not Grok Bot. Same pairing as Claude Code vs Claude, or Codex vs ChatGPT. A custom connector at grok.com/connectors does not install this product. Official MCP is grok mcp add.

​
Set up

Two routes lead to the same place. MCP hands Grok Build her 14 hosted tools with nothing installed locally. Her skill teaches the postqueen CLI when you want shell commands and JSON you can pipe.
1

Connect over MCP

One command writes ~/.grok/config.toml. The scoping options, the header variant and self-hosted URLs are on Grok Build over MCP.
2

Or install the CLI and skill

The skill is a playbook. It does not install the CLI. Get the key from app.postqueen.ai under Settings → API Keys.The repo also ships a Grok Build plugin (.grok-plugin/plugin.json and .grok-plugin/marketplace.json). Add the repo as a marketplace source; the identifier is postqueen@postqueen-agent. It loads the same skill and does not register an MCP server.
3

Verify

grok mcp list confirms the MCP server. A JSON list of channels from the CLI means the key works.
Grok Build can also load Cursor mcp.json and ~/.claude.json at lower priority. That is a compatibility fallback, not the official install. grok.com/connectors still does not register this product.

Ask in plain words:
Schedule a launch post about dark mode for tomorrow at 9am on X and LinkedIn.
It reads your channels with integrationList, then calls integrationSchedulePostTool. Want an image? Ask it to generate one. Not ready to publish? Ask for drafts. Posts land on the calendar at app.postqueen.ai. You can edit or delete them before they go out.
