Antigravity's whole idea is agents that work while you watch from a manager view, and social posting is exactly the kind of task worth delegating that way: important enough to do every week, boring enough that you never want to do it by hand.
planpo.st plugs in as an MCP server, one entry in the shared config. Since Antigravity 2.x the IDE, the agy CLI and the SDK read the same file, so you configure once and every surface can schedule posts.
Antigravity is Google's agentic development platform, an IDE and CLI built around autonomous agents on the Gemini models. It ships an MCP Store for one-click servers plus a raw config for custom ones, which is where planpo.st goes today.
When you finish the migration task, draft a post about the new feature for X and LinkedIn and put both in my approval queue.
The agent finishes its coding task, then calls create_post and submit_for_approval. You approve from the dashboard, the posts go out with tracked links, and the feature announcement never gets forgotten in the shipping rush.
You are my posting agent. Every Monday, read content-plan.md and fill the week on LinkedIn and Threads at the best times, drafts only.
One agent in the fleet owns the calendar. get_best_times picks slots, create_post fills them as drafts, and your Monday starts with a review instead of a blank week.
Summarize what last month's posts earned per platform.
get_revenue_overview returns attributed revenue, the agent writes the summary, and the number is real because it came from Stripe rather than from a reach metric.
Plenty of tools let an agent post. The difference here is what comes back: every link in a scheduled post can be tracked, payments from Stripe, Shopify or RevenueCat are matched to the exact post that caused them, and your agent can read those numbers with the same connection it used to publish. Google Antigravity does not just post for you, it finds out whether the post worked.
Google's agentic IDE and CLI. Since 2.x the IDE, the agy CLI and the SDK read one shared MCP config. Grab an API key from Settings, add the server with the local command and the tools appear. The full config, with the sharp edges called out, is on the setup page.
