Connect Gemini Spark to Brickmaster
Link Brickmaster as a custom Connected App in Gemini Spark, then use it from Gemini on web or mobile.
Set up Gemini Spark
Brickmaster remote MCP server
https://api.brickmaster.app/mcp- On gemini.google.com, open Settings & help → Connected Apps. If needed, open Personal Intelligence first.
- Under Custom apps for Spark, choose Add a custom app. If that section is not shown, this Google account does not expose the setup surface; use another Brickmaster AI app guide.
- Enter the Brickmaster MCP URL shown above, choose Next, and follow the browser flow. No Advanced credentials should be necessary because Brickmaster supports dynamic client registration.
- Sign in to Brickmaster, select the collections Gemini may read, and choose one default. Once connected on the web, the app is also available in Gemini Spark on mobile.
This applies to Gemini Spark custom apps. It does not mean every ordinary Gemini conversation or Google Workspace account can add an arbitrary MCP server.
What happens during authorization
The AI app opens Brickmaster in your browser. Brickmaster shows the requesting application and its exact return address, then asks you to sign in and choose which collections it may read. The AI app receives a Brickmaster-only MCP credential—never your Brickmaster sign-in token or Supabase session.
Never paste an API key, Supabase token, Brickmaster session, client secret, or custom Authorization header into the AI app. A compatible host discovers Brickmaster's public OAuth flow from the server URL.
What Gemini Spark can ask
- List only the collections you selected when connecting
- Summarize sets, minifigures, ownership, build states, brands, and locations
- Search your collection and inspect one item's safe catalog and build context
- Find duplicate copies and collectible-minifigure series gaps
- Compare LEGO theme progress and review bounded build history
- Search Brickmaster's global LEGO and alt-brick set catalog
Prompts to try
- “Do I own Rivendell, and how many copies do I have?”
- “Which sealed sets under 1,000 pieces could I build this weekend?”
- “Show my duplicate sets and loose minifigures.”
- “Which LEGO themes am I closest to completing?”
- “Summarize what I built this year and how long it took.”
Change access or disconnect
In Brickmaster, open Settings → AI connections. You can change this app's selected collections, disconnect it, or disconnect every AI app. Brickmaster revocation takes effect immediately even if Gemini Spark still displays the old connection.
The AI app processes tool inputs and results under its own terms, retention, and training policies. Brickmaster excludes email addresses, household members, prices paid, sellers, acquisition sources, private notes, OAuth details, and internal database fields. The connector cannot add, edit, or delete anything. Read Brickmaster's privacy policy for details.
