How to Connect StoreSEO MCP to Antigravity

Antigravity is Google’s agentic coding product. Its agent plans multi-step work in your project and can call tools exposed through the Model Context Protocol, from the IDE’s agent side panel.

This guide connects Antigravity to the StoreSEO MCP server at https://mcp.storeseo.com/mcp. Once connected, Antigravity can read your Shopify store’s SEO scores and settings and, when you agree, apply optimized meta, alt text, schema and other SEO changes. For what to ask once you are set up, see StoreSEO for Antigravity.

Before You Start

Server URL: https://mcp.storeseo.com/mcp
Sign-in: Antigravity supports OAuth through dynamic client registration, which StoreSEO’s server offers. Click Authenticate next to the server, approve your Shopify store in the browser, then paste the authorization code back. Or send a StoreSEO personal access token as an Authorization Bearer header.
Plan: The MCP server works on any active StoreSEO plan, including the free plan. A store with no active plan gets a message with a link to choose one in the app.
Access token (if you need one): create it in the StoreSEO app under Settings, AI Toolkit. Treat it like a password.

Connect StoreSEO to Antigravity

Step 1: Add StoreSEO in View raw config

In the Antigravity IDE open the menu in the agent side panel, choose MCP Servers, then Manage MCP Servers, then View raw config. Paste this into mcp_config.json and save. The field is serverUrl: Antigravity does not support url or httpUrl for remote servers.

{
  "mcpServers": {
    "storeseo": {
      "serverUrl": "https://mcp.storeseo.com/mcp"
    }
  }
}

Open Agent settings (Cmd+, on Mac, Ctrl+, on Windows and Linux), go to Customizations and click Authenticate next to storeseo. Pick your Shopify store and approve in the browser, copy the authorization code it shows, paste it into the settings panel and click Submit. Then ask this in the agent panel.

Other Ways to Connect

Option: Connect with an access token

If you cannot use the browser sign-in, generate a token in StoreSEO under Settings, AI Toolkit and add it as a header. Keep mcp_config.json out of a public repository when it holds a token.

{
  "mcpServers": {
    "storeseo": {
      "serverUrl": "https://mcp.storeseo.com/mcp",
      "headers": { "Authorization": "Bearer YOUR_TOKEN" }
    }
  }
}

Check the Connection

Start a new session and send this prompt. Antigravity should call StoreSEO and answer with your store’s real SEO score.

What to Ask Antigravity

Use StoreSEO to list my five lowest-scoring products and preview new meta for each.
Which product images are not optimized? Show me the list before you compress anything.
Is my llms.txt up to date? If not, say what generating a new one will publish and cost.
Show me Search Console queries for the last 28 days where we rank between 8 and 20.
Which products have no FAQ or AI snippet yet? Preview them for the first three.

How Approvals Work

Reads such as SEO scores, store listings, settings and Google reports run straight away. Generating a preview spends AI credit but writes nothing, and StoreSEO tells the agent to say what a generation will cost before it runs one. Applying content, optimizing images, changing settings, publishing llms.txt or agents.md, writing a product description and deleting anything wait for your yes in the conversation. That yes is an instruction the agent follows, not a lock on the server, so your client’s own tool-approval setting is the hard stop.

Things to Know About Antigravity

The field is serverUrl. Antigravity’s documentation says legacy fields such as url or httpUrl are not supported, so an entry copied from another client will not connect until you rename it.
The sign-in ends with a code you paste back into Agent settings, under Customizations, so do it in the same window where you started it.
If you add a policy that allows mcp(storeseo/*), Antigravity stops asking and the confirmation StoreSEO asks the agent for is the only check. Allow individual read tools instead.

Disconnect

Remove the StoreSEO server in Antigravity, then revoke the connection or the access token in the StoreSEO app under Settings, AI Toolkit, where every connected client is listed.
