Antigravity Social Media MCP Config

Google Antigravity connects to a social media MCP server by pasting one JSON config with your API key in the headers, then restarting the app. Antigravity shares its MCP configuration across the IDE, the CLI, and the SDK, so the server you add once is available to all three rather than needing a separate setup per surface.

How do I know it worked?

Ask Google Antigravity to list your connected accounts. It calls blotato_list_accounts and returns your platforms, which confirms both the connection and the authentication in one step. If you see your accounts, setup is done.

First prompt to run

What social media accounts do I have connected?

An AI agent answering "what social accounts do i have connected?" by calling Blotato and listing 10 connected social media accounts across Twitter, Bluesky, Instagram, Threads, LinkedIn, Facebook, YouTube, Pinterest, and TikTok — The reply you are looking for: the agent calls Blotato and lists every connected account. Here it returns 10 accounts across all nine platforms.

Worth knowing before you rely on it: analytics prompts only return data for X, Instagram, Facebook, Threads, and Bluesky. The other four platforms publish normally but report no metrics yet.

What breaks, and how to fix it

The most common Antigravity failure is a JSON error rather than an auth error: a missing comma between sections, or single quotes swapped in for the double quotes Blotato gives you. Single quotes are a shell and .env convention and are not valid JSON. Validate the block before assuming the key is wrong.

What is different about Google Antigravity

Antigravity is the only agent here whose MCP config is shared across three surfaces at once, so adding the server in the IDE also gives the CLI and the SDK the same publishing tools without a second config.

FAQ

Google Antigravity social media FAQs

01 Can Google Antigravity post to social media?

Yes. Google Antigravity cannot reach a social account on its own, because it has no platform credentials. Connecting it to Blotato's hosted MCP server at https://mcp.blotato.com/mcp gives it tools to publish and schedule across nine platforms: X, LinkedIn, Facebook, Instagram, TikTok, YouTube, Threads, Bluesky, and Pinterest. Google Antigravity authenticates with api key header.

02 How do I connect Google Antigravity to social media?

03 How do I set up Google Antigravity for social media?

Setting up Google Antigravity for social media takes one connection. Connect your social accounts in Blotato, then give Google Antigravity the hosted MCP endpoint https://mcp.blotato.com/mcp and authenticate with api key header. For Google Antigravity specifically that means: mcp json, shared across the ide, cli, and sdk. Once it loads, Google Antigravity can publish and schedule to X, LinkedIn, Facebook, Instagram, TikTok, YouTube, Threads, Bluesky, and Pinterest from a plain-language prompt.

04 What is the best way to manage social media with Google Antigravity?

Let Google Antigravity do the drafting and decision making, and let a publishing layer hold the accounts and the schedule. The thing that makes this work on Google Antigravity in particular: Antigravity is the only agent here whose MCP config is shared across three surfaces at once, so adding the server in the IDE also gives the CLI and the SDK the same publishing tools without a second config.

05 What goes wrong when connecting Google Antigravity?

06 Does Google Antigravity need to be running for a scheduled post to go out?

No. Scheduling runs on Blotato rather than inside Google Antigravity. Once the agent queues a post, it publishes at the scheduled time whether or not Google Antigravity, your terminal, or your laptop is on. This is the practical difference between an agent that drafts and a system that runs unattended.

07 Do I need a developer app or platform API keys to use Google Antigravity this way?

No. Blotato holds the platform integrations and manages the OAuth tokens, including refreshes. You connect each social account through a normal login flow instead of registering your own app on every network and waiting for review. Google Antigravity never handles a platform credential.

08 What can Google Antigravity not do on social media?

Publishing and scheduling cover all nine platforms, but the rest is uneven and worth knowing before you build against it. Analytics covers X, Instagram, Facebook, Threads, and Bluesky. Comments and direct messages cover Instagram and Facebook. Keyword-triggered DM automation is not available at all. None of that varies by agent: it is the same surface whichever client you connect.

09 How much does it cost to connect Google Antigravity?

Starter is $29/mo flat for 20 connected accounts, and the price does not scale with posting volume. API and MCP access is not part of the 7-day trial: generating a key activates the paid Starter plan, so plan on subscribing rather than trialing it.

Connecting a different agent?

Same endpoint, same accounts, one setup per client. The AI agents for social media hub covers what all of them share, including every tool your agent can call.
