Antigravity BulkPublish

Post to social media from Antigravity

Antigravity's agents can already plan and carry out work across your code. Give them BulkPublish and posting becomes one more task they can finish, from a launch thread to a month of scheduled updates.

What Antigravity can do

On the hosted server, Antigravity gets 20 tools covering posts, media, channels and analytics. Every agent that connects gets this same set. Run the server on your own machine from the npm package and it adds the rest, such as labels, recurring schedules and RSS feeds.

Where the posts go

Whatever Antigravity schedules can go to any of these 15 networks, to one account or to all of them at once. Each one links to its own page with its limits and post types.

Setting up Antigravity

Add the server through the MCP Store or by editing the config file below. Note the key name: Antigravity wants serverUrl where most clients say url, and a server entered with the wrong key fails without an error.

  1. Create a BulkPublish account. The free plan connects three channels and does not ask for a card.
  2. Add the hosted MCP server to Antigravity with the configuration below. The address is https://mcp.bulkpublish.com/mcp and there is no key to copy.
  3. Sign in when Antigravity asks you to. That sign-in is OAuth 2.1, so the token stays with Antigravity and you can revoke it from your account at any time.
  4. Ask it to post something. It can see your channels, your queue and your analytics from the first message.

Configuration for Antigravity

Add this to ~/.gemini/config/mcp_config.json:
{
  "mcpServers": {
    "bulkpublish": {
      "serverUrl": "https://mcp.bulkpublish.com/mcp"
    }
  }
}
Or run the server yourself, with an API key instead of signing in:
{
  "mcpServers": {
    "bulkpublish": {
      "command": "npx",
      "args": [
        "-y",
        "@bulkpublish/mcp-server"
      ],
      "env": {
        "BULKPUBLISH_API_KEY": "bp_your_api_key"
      }
    }
  }
}

Prompts to start with

Once Antigravity is connected, paste one of these to get going. Swap anything in square brackets for your own details.

See what is connected
Show me my BulkPublish channels, then list everything scheduled on them for the next seven days. Tell me which channels have nothing queued.
Draft one post and queue it
Write a LinkedIn post about [your topic]. Keep to my usual voice: [describe it in a line]. Show me the draft first, and once I say yes, schedule it in BulkPublish to the next free slot in my queue.
Turn a link into posts
Read [paste a URL] and turn it into one post for each of my connected BulkPublish channels, adapted to what works on each network rather than the same text everywhere. Schedule them for next Tuesday morning. Show me all of them before you schedule anything.
Plan a week in one pass
Here are five things I want to post about this week: [list them]. Create a BulkPublish post for each, spread across the free slots in my queue so nothing goes out back to back, and show me the finished week when you are done.
Post an image with caption options
Upload [file path, or attach the image] to my BulkPublish media library, then write three caption options for Instagram, each with a different angle. Once I pick one, schedule it with that image.
Check the next two weeks
List everything scheduled in BulkPublish for the next fourteen days, grouped by day. Flag anything duplicated, anything going out at an odd hour for its network, and any day with nothing at all.
Fix what failed
Find any BulkPublish posts that failed in the last seven days. For each one, tell me in plain language what went wrong, then retry only the ones that look like a temporary problem and tell me which ones need me to fix something first.
Read the numbers back
Pull my BulkPublish analytics for the last thirty days. Tell me the three posts that did best, what they have in common, and one thing I should do more of next month. Use my numbers, not general advice.

Ways teams use this

For teams already handing multi-step jobs to Antigravity who want the announcement step included rather than left for someone to do afterwards.

  • Bulk upload a month of posts in one pass, then let the queue send them out at the times you set.
  • Write once and cross-post everywhere. One post, adapted per network, goes to every connected channel together.
  • Turn a blog or podcast RSS feed into automatic posts the moment a new item appears.
  • Read the numbers back. Impressions, engagement and link clicks come back the same way the posts went out.

Frequently asked questions

What people usually want to know before they connect Antigravity.

Can Antigravity post to social media on its own?

Yes, once you have connected it. Antigravity reaches the same API the app uses, so it can write a post, put it in the queue, publish it, and read the numbers back. Everything it schedules appears in your content calendar, so you can look before it goes out.

Do I need an API key?

No. The hosted server uses OAuth 2.1, so you sign in once in your browser and Antigravity holds a token from then on. You can revoke that token from your account at any time, and nothing else stops working.

Which networks can it publish to?

All 15 of them. Antigravity sees the same channel list you do, so it can publish to one account or to every account at once, and it can adapt the wording per network in the same call.

Is anything installed on my machine?

No. The server is hosted, so Antigravity connects to a web address. There is nothing to run locally and nothing to keep updated, and it works the same on every machine you sign in from.

Can I review what it writes before it publishes?

Yes. Ask it to save drafts rather than publish, or turn on approvals so every post waits for a person. Both are ordinary BulkPublish settings and they apply whatever created the post.

Does agent access cost extra?

No. It is part of every plan, including the free one. Posts an agent schedules count against your plan exactly like posts you write in the app.

BulkPublish also works with 28 other tools. Pick one to see how it connects.
