Connect Cursor to Brickmaster
Configure Brickmaster as a remote Streamable HTTP MCP server in Cursor, then authenticate from its MCP tools panel.
Set up Cursor
Brickmaster remote MCP server
https://api.brickmaster.app/mcp- Open Cursor Settings → Tools & Integrations → MCP Tools, then open the global MCP configuration file.
- Add the configuration below, save it, and enable Brickmaster in the MCP tools panel.
- Choose the authentication action. Sign in to Brickmaster, select at least one collection, and choose one default.
- Confirm Brickmaster's tools appear in Available Tools, then ask a collection question.
~/.cursor/mcp.json
{
"mcpServers": {
"brickmaster": {
"url": "https://api.brickmaster.app/mcp"
}
}
}If Cursor proposes a `cursor://` OAuth callback rather than HTTPS or localhost, stop there. Brickmaster deliberately rejects interceptable private-app callbacks.
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 Cursor 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 Cursor 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.
