Connect Postsale to Your AI Platform
Step-by-step guide to connecting Postsale's MCP server to Claude, ChatGPT, Cursor, Windsurf, and other MCP-compatible AI platforms.
Connect Postsale to your AI assistant and manage your shipping workflow through simple, natural conversations. Once connected, your AI can search orders, compare carrier rates, create shipping labels, track packages, and pull analytics, all without switching between apps.
Think of it as having a shipping assistant built directly into your AI.
What is MCP?
MCP (Model Context Protocol) is an open standard that lets AI assistants connect to external services securely. Think of it as a universal plug that lets your AI talk directly to Postsale. You authorize the connection once, and your AI discovers all 37 tools automatically.
Real-World Example
We use Claude to manage our day-to-day operations and want to connect Postsale so we can handle shipping without switching between tools. We want to create shipping labels, check order statuses, and pull shipping reports directly from our AI.
You can do all of that with Postsale’s MCP connector, which gives your AI access to 37 powerful shipping tools. Setup only takes a few minutes, depending on the AI platform you are using.
What You Can Do
Once connected, your AI platform automatically detects and gives you access to 37 tools across five key areas:
Orders
Search, create, update, and manage your orders. Update statuses individually or in bulk, archive and restore orders, add tags for organization, and view order counts with filtered summaries.
Shipping and Labels
Compare real-time rates across USPS, UPS, and FedEx. Create shipments, purchase labels, and void labels. The Create Label tool handles the entire workflow in one step. It finds the order, compares rates, selects a service, purchases the label, and returns the tracking number.
Package Tracking
Check the current tracking status, scan events, and delivery progress for any shipment. Monitor tracking status counts across all shipments.
Analytics and Reporting
Pull revenue totals, shipping cost breakdowns by carrier, order volume over time, and top-shipped products. Get dashboard-style insights without opening a browser.
Account and Configuration
View your Postsale plan and account details, view connected carriers and storefronts, check connection status, and review available order statuses and saved filters.
Sample Prompts
Here are a few things you can ask your AI assistant:
-
"What's the cheapest way to ship order #1042 to California?" - Compares rates across all carriers and presents your options. Confirm to create the label.
-
"How much did I spend on shipping this week?" - Pulls costs by carrier, shipment counts, and revenue.
-
"How many orders are on hold right now?" - Searches by status and shows a count. Ask it to update them if needed.
-
"What are my options for shipping order #1087?" - Compares rates across USPS, UPS, and FedEx and presents the results.
-
"How many orders shipped this month?" - Returns shipment counts with optional carrier and store breakdowns.
