What is the Constructor MCP Server?
Connect your Constructor.io account to any AI agent and take full control of your site search and product discovery workflows through natural conversation.
What you can do
- AI-Powered Search — Execute ML-ranked product retrieval dynamically mapped to e-commerce signals and user intent
- Predictive Autocomplete — Access fast predictive typing boundaries and trace exact matched categories for any partial query
- Dynamic Recommendations — Surface personalized products using collaborative filtering models and custom recommendation pods
- Category & Brand Browsing — Navigate through product directory trees and manufacturer taxonomies without any query bias
- Advanced Filtering — Apply strict attribute filters (colors, sizes, features) and custom sort rules to refine product discovery results
- Collection Management — Retrieve curated marketing clusters and static collections accurately for promotional auditing
How it works
1. Subscribe to this server
2. Enter your Constructor.io Public API Key (found in Dashboard > Integration)
3. Start optimizing your e-commerce discovery from Claude, Cursor, or any MCP-compatible client
Who is this for?
- E-commerce Managers — audit search rankings and recommendation pods without manual dashboard testing
- Product Owners — monitor category browsing performance and verify attribute filtering logic in real-time
- Developers — test and debug search API parameters and personalized recommendation outputs through natural language
- Marketing Teams — verify that curated collections and brand taxonomies are correctly mapped and rankable

Why teams choose Vinkius for Constructor in OpenAI Agents SDK
The Constructor MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 10 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in OpenAI Agents SDK only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.

How Vinkius secures
Constructor for OpenAI Agents SDK
Every tool call from OpenAI Agents SDK to the Constructor MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Can my agent check the ML ranking for a specific product search?
Yes. Use the 'search_products' tool. The agent will retrieve results ranked by Constructor's ML engine, allowing you to audit how products are surfaced based on specific keywords and intent signals.
How do I retrieve personalized recommendations via the agent?
Provide the 'pod_id' to your agent and use the 'get_recommendations' tool. The agent will query the collaborative filtering models to return a list of products tailored to your specified recommendation logic.
Can I test attribute filtering like color or size through chat?
Absolutely. The 'search_filtered' tool allows you to pass exact attribute mappings (e.g., 'color:blue,size:L'). Your agent will verify how the API restricts results to those specific structural bounds.
How does the OpenAI Agents SDK connect to MCP?
Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.
Can I use multiple MCP servers in one agent?
Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.
Does the SDK support streaming responses?
Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
