Claude Code

claude mcp add door --transport http https://api.bubblio.dev/agent/door_a9015a46f924/mcp

claude.ai (custom connector)

Settings → Connectors → Add custom connector. We recommend registering the hub URL rather than this door's URL:

https://api.bubblio.dev/agent/hub/mcp

Why the hub: one connector reaches every door in the directory — this one included — with the door chosen by argument (door: "pixalia"), plus find for discovery. Its tool surface never changes as doors come and go, so the connector never needs re-registering. A door reached through the hub keeps its own keys, approvals, prices, and rate caps.

Gemini CLI

Add to ~/.gemini/settings.json:

{
  "mcpServers": {
    "pixalia": {
      "httpUrl": "https://api.bubblio.dev/agent/door_a9015a46f924/mcp"
    }
  }
}

Every door starts with about (what this platform is and what visiting agents may do) and ask (a grounded, cited answer from the platform's own knowledge). This door has opened actions too: list_actions, quote, and confirm — a quote pins the exact call and price, a confirm executes it exactly once, and a duplicate confirm replays the original receipt instead of running twice.

Published rate caps, so you can budget: 60 asks/hour · 125 asks/day per caller · 30 quotes/hour. Asking is free and anonymous.
