Connect your ContextBolt account For OAuth, add https://seo.contextbolt.app/mcp and complete sign-in with your SEO account email and email code, then allow access. If your client cannot complete OAuth, follow the personal-URL compatibility steps on this page. Get that private URL from your ContextBolt SEO welcome email. Use one connection method.

Personal-URL setup: Open the raw MCP config In Antigravity open Settings, then the Customizations tab, then Manage MCP Servers, then View raw config. That opens mcp_config.json in the editor. You can also reach it from the ... menu in the Agent panel under MCP Servers.

Personal-URL setup: Add the server and refresh Under mcpServers add: "contextbolt-seo": { "serverUrl": "https://seo.contextbolt.app/mcp/YOUR_TOKEN" }. Save the file, then hit Refresh in the MCP Servers panel. Antigravity uses serverUrl for remote HTTP servers, not url.

Personal-URL setup: Check it and connect Search Console (optional, free) Ask the agent 'what SEO tools do you have?' to confirm the tools loaded. Then ask 'connect my Google Search Console' and approve read-only access to read your real clicks, positions, and quick wins. The Search Console tools are free and never spend your monthly credits.

Then ask it something real.

“What keywords should my new pricing page target?” The agent calls keyword_research and returns related terms with volume, difficulty, and intent, so you can plan the page while you build it.

“How hard is 'gemini mcp server' to rank for, and who's in the top 10?” Chains keyword_difficulty and serp_overview so you get a difficulty score and the live page-one results without leaving the editor.

“What does supabase.com rank for, and who else competes?” Runs ranked_keywords then competitor_keywords for a content map plus the rivals chasing the same terms.

“Who links to my main competitor but not to me?” Calls backlink_gap and returns a spam-scored prospect list, a ready-made outreach shortlist. Backlink calls cost three credits each.

The longer story.

Antigravity is Google’s agentic development platform, a VS Code-based editor with an Agent Manager that runs tasks on your behalf. It speaks the Model Context Protocol, so you can plug in ContextBolt SEO and pull live keyword, SERP, domain, and competitor data into the surface where you are already building.

Every lookup you run lands on your SEO Dashboard, a private page you sign in to from any machine. Your research stops vanishing into the chat and becomes a record you can scroll, filter and export.

SEO research inside the Antigravity agent

The best time to decide what a page should rank for is while you are building it. With ContextBolt SEO connected, you ask “what should this target, and who already owns it?” and the answer lands in the chat. Every answer is saved to your SEO Dashboard, with no export and no context switch.

Because these are MCP tools, the agent chains them. “Find five low-difficulty keywords for my features page, check who ranks for each, and note the gaps” is one prompt that calls several tools and files the whole session on your dashboard.

The Antigravity mcp_config.json entry

Use https://seo.contextbolt.app/mcp and complete the browser sign-in if your client supports remote MCP with OAuth. Enter your SEO account email and email code, then allow the connection. For a client that cannot complete that flow, use the personal-URL compatibility configuration shown here. Copy the full private URL from your ContextBolt SEO welcome email and replace the example URL with it.

Open the config from Settings, then Customizations, then Manage MCP Servers, then View raw config. Add ContextBolt SEO under mcpServers:

{
  "mcpServers": {
    "contextbolt-seo": {
      "serverUrl": "https://seo.contextbolt.app/mcp/YOUR_TOKEN"
    }
  }
}

Note the key is serverUrl, not url. Antigravity inherits this from Windsurf’s config style, and it is the one detail that trips people up coming from Cursor or VS Code, where the same field is called url. Because your token sits in the URL path, you do not need a headers block, though Antigravity supports one for servers that want a bearer token.

Save the file, hit Refresh in the MCP Servers panel, and ask “what SEO tools do you have?” to confirm. Your URL holds a personal token, so keep the config off public repos. The full tour of tools and workflows is in the ContextBolt SEO guide, and if you are weighing the options first, the comparison of SEO MCP servers covers the alternatives honestly.

Common questions.

Where is the Antigravity MCP config file?

The reliable route is the UI: Settings, Customizations, Manage MCP Servers, View raw config. That opens the file wherever your build keeps it. On disk it is mcp_config.json under your home .gemini folder. Antigravity 2.0 moved it to a shared location so the IDE and the CLI read the same config, and earlier builds keep it in an antigravity subfolder, so open it from the UI rather than guessing the path.

Should I use url or serverUrl?

serverUrl. Antigravity expects serverUrl for a remote HTTP MCP server like ContextBolt SEO, where Cursor and VS Code expect url. This is the single most common reason the tools do not appear. If they are still missing, check you pasted the full URL and pressed Refresh in the MCP Servers panel.

Does this work in the Antigravity CLI as well as the editor?

Yes. Antigravity 2.0 shares one MCP config between the editor and the CLI, so a single entry lights up both. The tools behave identically because ContextBolt SEO is a remote server and does nothing client-specific.

Where does my research get saved?

To your ContextBolt account, and it shows up on your SEO Dashboard, a private page that fills itself as you work. It is one URL, so the research follows you between machines and between agents instead of living in one project folder. Saving is free and never counts against your 1,000 monthly credits.

How many credits does a question cost?

Research tools cost one credit each. Backlink tools cost three each. The plan includes 1,000 a month, top-ups never expire, and checking your balance is free.

Can I keep my token private?

Yes. Your MCP URL contains a personal token, so treat it like a password. Keep mcp_config.json off public repos, and if you share a machine, remove the server when you are done.
