Audit Constructor catalog logic directly in Claude Desktop

The `search_products` tool lets Claude Desktop query your headless Constructor.io platform using this MCP Server to find and analyze CRM records. Your agent can run search queries, check product placements, and verify exactly how items appear to customers. Using `search_filtered` and `search_sorted` lets you restrict arrays to specific colors or sizes while pulling billing rules. Your agent handles the heavy lifting of checking product distributions right inside your chat window without leaving the app.

Expose active merchant logic and gateway states

The `autocomplete` tool extracts structural properties driving active Account logic. Claude Desktop uses this data to map out how search suggestions behave for different customer profiles. You can also run `browse_collection` to identify active arrays spanning native Gateway auth. This gives your agent the context it needs to diagnose checkout-adjacent catalog issues on the fly.

Inspect plan math and brand arrays

The `browse_brand` tool inspects deep internal arrays to verify specific Plan Math. Your agent parses this telemetry to ensure your brand pages align with your active commercial agreements. When you run `browse_category`, Claude Desktop provisions a raw JSON payload with hard Customer bindings. This helps you verify category landing pages are serving the correct items to the correct user tiers.
