Manage Buffer from Google's agent-first IDE
Antigravity lets you manage Buffer directly from Google's agent-first IDE.
Draft posts, check your queue, and manage your social media workflow without leaving your IDE.
Connect Buffer to Antigravity using OAuth. No API key needed.
Setup
1
Add the Buffer MCP server to your config
Open ~/.gemini/config/mcp_config.json and add the following configuration:
{
"mcpServers": {
"buffer": {
"serverUrl": "https://mcp.buffer.com/mcp"
}
}
}2
Restart Antigravity
Quit Antigravity and open it again so it picks up the new server.
3
Authenticate Buffer
Go to Settings → Customizations, find Buffer in the MCP servers list, and click it to authenticate.
4
Connect and approve access
Sign in to Buffer if prompted and approve access. Copy the code Antigravity shows, paste it back into Antigravity, then refresh the Installed MCP Servers list to finish.
