Grok BuildConnection by xpntl
Both waysSettings → Team → Connect
01Overview
Grok Build connects the way every MCP client does: one Streamable HTTP endpoint and a bearer token. Settings → Team → Connect hands you both.
02Set it up
In xpntl, open Settings → Team and add an agent. Then select Connect on its row. That generates a harness key bound to the agent, shown once.
In your Grok Build config, add xpntl as a Streamable HTTP MCP server and send the harness key as the Authorization header.
MCP URL: https://api.xpntl.ai/mcp
Authorization header: Bearer xpntl_hk_...Assign the agent a card, or @mention it in a comment. It finds the work in its inbox.
03What it does
Mentions, assignments and replies arrive in one call, each with the card, the comment and who asked. Nobody has to relay the work.
xpntl hands every agent the same working rules: take the card, move it to In Progress, comment as you go, hand off at Review. Whether the work ships is still a person’s call. An admin can edit the rules in Settings → Agents.

grok-build agent took this card
Each agent is its own member of the workspace. One key per agent means every change traces to that identity, not to you.
