How do I get a Rebrickable API key?

Visit [**rebrickable.com/api**](https://rebrickable.com/api/), sign in with your Rebrickable account, and your API key will be displayed on the page. Copy it — it's a long alphanumeric string.

Can I search for sets by theme?

Yes! Use `list_sets` with `theme_id` to filter by theme. First use `list_themes` to find the theme ID (e.g. Star Wars = 170), then pass it to list_sets. You can also filter by year or part number.

Can I see the parts inventory for a set?

Yes! Use `get_set_parts` with the set number (e.g. "75192-1" for the Millennium Falcon). Returns every part with its part number, color ID, quantity and whether it's a spare. Set inc_minifig_parts to true to include minifig parts.

How many results can I get at once?

The API supports up to 1000 results per request. Use the `page_size` parameter (max 1000, default 100) and `page` for pagination. The total count and next/previous URLs are returned in each response.

Rebrickable LEGO + Cursor FAQ

Common questions about integrating Rebrickable LEGO MCP Server with Cursor.

What is Agent mode and why does it matter for MCP?

Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.

Where does Cursor store MCP configuration?

Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.

Can Cursor use MCP tools in inline edits?

No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.

How do I verify MCP tools are loaded?

Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
