Behavry Integration — Google Antigravity

Google Antigravity supports MCP servers natively via ~/.config/antigravity/mcp.json. Behavry connects as a Streamable HTTP MCP server.

Prerequisites​

  • Behavry stack running (make dev or docker compose up)
  • Google Antigravity installed
  • Python 3.11+

Config File Location​

~/.config/antigravity/mcp.json

Quick Setup​

make setup

This detects Antigravity, provisions an antigravity-local agent, and merges the MCP server config into ~/.config/antigravity/mcp.json.

Manual Configuration​

Add to ~/.config/antigravity/mcp.json:

{
  "mcpServers": {
    "behavry": {
      "transport": "streamable-http",
      "url": "http://localhost:8000/mcp/v1/",
      "headers": {
        "Authorization": "Bearer <behavry-jwt>"
      }
    }
  }
}

Activate​

  1. Open Antigravity → Settings → Extensions → MCP Servers
  2. The Behavry server should appear with a connected status
  3. If not visible, restart Antigravity

Verify​

  1. Invoke a tool in Antigravity (e.g., "List files in the current directory")
  2. Check http://localhost:5173 → Live Activity for the event

Token Refresh​

make tokens

Antigravity picks up the new token on the next MCP request without requiring a restart.
