Squarespace MCP Integration

Weldable's Squarespace MCP integration lets your AI agents interact with your Squarespace site's commerce data, inventory, and orders through natural language. Squarespace provides a set of commerce APIs for managing products, orders, inventory, and transactions, and Weldable wraps these into actions your agent can call alongside other services like Slack, Google Sheets, and Gmail.

For store owners who chose Squarespace for its design-first approach, this integration adds the operational automation layer that the platform's built-in tools do not cover. Your agent handles the repetitive data work while you focus on your brand.

Use cases

Daily sales reporting

Your agent queries Squarespace orders from the last 24 hours, calculates total revenue and average order value, and posts a summary to Slack. It breaks the numbers down by product category so you can see what is selling. Run this on a schedule and your team gets a morning briefing without logging into the dashboard.

Inventory reconciliation

Your agent reads current stock levels from Squarespace and compares them against a master inventory spreadsheet in Google Sheets. It flags any mismatches: products that show as in-stock on the site but are marked depleted in the spreadsheet, or vice versa. The discrepancy report goes to Slack so your operations team can investigate.

Order fulfillment tracking

Your agent monitors orders that have been paid but not yet fulfilled. It compiles a list with customer names, order contents, and shipping addresses, then posts it to a dedicated Slack channel each morning. When an order ships, your agent updates the status and notifies the customer via Gmail with tracking details.

Product performance analysis

Your agent pulls order data over a specified period, aggregates sales by product, and ranks them by revenue and unit volume. It formats the results into a Google Sheet with trends over time. Use this to identify your best sellers and products that might need better positioning or promotion.

How it works

Connect your Squarespace site using API keys generated from your site's developer settings. Weldable authenticates requests using these keys with the specific permissions your workflows need. The connection covers the Commerce API for orders, inventory, and transactions.

Once connected, describe what you need. Say "show me all unfulfilled orders from this week" and Weldable translates that into the correct API call, parses the response, and returns structured results. Your agent can chain Squarespace data with other integrations: pull orders, analyze them, and push reports to Slack or Google Sheets.

Tips

Squarespace API access requires a Commerce plan. The commerce APIs are only available on Business and Commerce plans. Basic and Personal plans do not expose order or inventory endpoints. Verify your plan level before setting up the integration.

Product variants have independent inventory. Each variant (size, color, etc.) tracks its own stock level. When your agent checks inventory, it needs to look at the variant level to get accurate numbers. A product can show as "in stock" even if most variants are sold out.

Order status values are specific to Squarespace. Orders use statuses like PENDING, FULFILLED, and CANCELED rather than generic terms. Your agent should reference these exact values when filtering or reporting on orders.

Transaction data includes fees and taxes. The transactions API returns gross amounts, Squarespace fees, payment processor fees, taxes, and net amounts separately. When your agent calculates revenue, make sure it is using the right field for your reporting needs.

Rate limits are modest. Squarespace enforces rate limits on API calls. For stores with large catalogs or high order volumes, structure your agent's queries to request only the data it needs and avoid unnecessary full-catalog scans.
