Setup
Setup guide
- 11. In Switchy, open Settings and navigate to the MCP Integrations section. 2. Click 'Add Integration' and select ShipEngine from the list. 3. Log into your ShipEngine account at ship.shipengine.com and go to API Management under Settings. 4. Generate a new API key with permissions for rates, labels, tracking, and address validation. 5. Copy the key and paste it into Switchy's configuration dialog, then click 'Connect'. 6. Switchy will verify the key by making a test API call to ShipEngine's carriers endpoint. 7. Once connected, open any Space and type '@ShipEngine list my configured carriers' to confirm the integration works. 8. The MCP will respond with your active carrier accounts, proving it can access your shipping setup.
What teammates see: by default, memories from Shipengine are scoped to the Space (PROJECT visibility) - you can mark any memory PRIVATE or share it ORG-wide.

@shipengine what are the cheapest shipping rates for a 2lb package from New York to Los Angeles, arriving by Friday?
Based on current carrier rates, here are three options for your 2lb package (10×8×6 inches assumed) from New York 10001 to Los Angeles 90001 with Friday delivery: USPS Priority Mail at $9.45 (2-day transit), UPS Ground at $12.30 (3-day transit, may miss Friday cutoff), and FedEx 2Day at $18.75 (guaranteed Friday arrival). USPS Priority offers the best value if you ship by Wednesday morning. All rates include residential delivery and basic tracking.
This example shows rate-shopping across carriers, a core ShipEngine capability. Requires API key with rate-fetching permissions. Actual rates fluctuate daily based on fuel surcharges and dimensional weight calculations. The MCP cannot purchase labels without explicit create-label tool invocation.
@shipengine create a shipping label for this order: ship to Maria Chen, 450 Sutter St, San Francisco CA 94108, using the USPS Priority Mail rate we just quoted.
Label created successfully. Tracking number: 9400111899562814736908. The label PDF is ready for download and has been charged to your ShipEngine account at $9.45. The package is expected to arrive by Thursday, January 16th. Remember to affix the label to a box that matches the declared dimensions (10×8×6 inches) and drop it at any USPS location by 5pm today for on-time delivery.
This write action generates a billable label and commits funds from your carrier account. ShipEngine debits your balance immediately. The MCP needs create-label permissions and a validated ship-from address already configured in your account. Label PDFs expire after 30 days if not printed.
@shipengine track all shipments from the past week and flag any that show delivery exceptions or delays.
Scanned 47 shipments created January 6-12. Three require attention: Tracking 1Z9Y86420348675319 (UPS) shows 'weather delay' in Denver, now estimated Monday instead of Friday. Tracking 9261290100129790891539 (FedEx) has 'address correction needed' — recipient moved, requires sender action. Tracking 9400116901496748365732 (USPS) delivered successfully but recipient reported package damaged. All other shipments are in transit or delivered without issue.
This synthesis example combines tracking data retrieval with AI-driven filtering. Useful for proactive customer service. ShipEngine's tracking updates lag 15-60 minutes behind carrier systems. The MCP cannot auto-resolve exceptions — you'll need to contact carriers directly for address changes or damage claims.
Use-case deep-dives
When ShipEngine makes sense for small online stores
A 3-person Shopify store shipping 50-200 orders a week needs carrier rate comparison and label printing without building integrations from scratch. ShipEngine wins here because it normalizes UPS, FedEx, USPS, and DHL into one API—your team writes one set of prompts instead of four. The API key auth means you can share a Switchy workspace where anyone can check shipment status or print a replacement label without waiting on the founder. The threshold: if you're only using one carrier or your volume is under 20 orders a week, the setup overhead probably isn't worth it. For teams doing multi-carrier fulfillment at small scale, this MCP turns shipping ops into a shared AI task instead of a founder bottleneck.
Why support teams reach for ShipEngine in Switchy
A 5-person support team handling 'where's my order' tickets spends 15 minutes per ticket toggling between Zendesk, Shopify, and three carrier portals. ShipEngine consolidates tracking across carriers, so a support agent can ask Switchy 'what's the status of order 4829' and get a real-time answer without leaving the thread. The API key setup means the whole team shares one integration—no per-seat carrier logins. This works when your ticket volume justifies the API cost and you ship with multiple carriers. If you're a single-carrier shop or tickets are under 10 a day, manual lookup is faster. For multi-carrier support teams, this MCP turns a 15-minute lookup into a 30-second prompt.
When finance teams use ShipEngine for shipping spend review
A startup CFO reviewing monthly shipping costs needs to compare what you paid versus what you were quoted across 4 carriers and 800 shipments. ShipEngine's rate-shopping API lets you pull historical rates and actual charges into Switchy, then ask 'which carrier overcharged us last month' or 'what would we have saved routing through USPS'. The API key auth means the finance lead doesn't need engineering help to run the analysis. The catch: if your shipment data lives in a custom WMS or you're doing under 200 shipments a month, exporting CSVs and using a spreadsheet is simpler. For teams doing 500+ monthly shipments with rate variance, this MCP turns a quarterly audit into a monthly check-in.
Frequently asked
What does the ShipEngine MCP do in Switchy?
The ShipEngine MCP connects your team's shipping operations to Switchy's AI workspace. Your agents can query shipment statuses, retrieve tracking information, and pull carrier rate comparisons without leaving the conversation. Since ShipEngine aggregates multiple carriers (USPS, FedEx, UPS), you get a single interface for all your logistics queries instead of juggling separate carrier portals.
Do I need admin access to connect ShipEngine?
You need a ShipEngine API key, which typically requires account admin permissions to generate. The key authenticates all requests from Switchy to your ShipEngine account. If your team already has a key for other integrations, you can reuse it — ShipEngine doesn't limit keys to single applications. Just paste it into Switchy's connection flow and you're done.
Can the ShipEngine MCP create shipping labels?
The MCP focuses on read operations — tracking shipments, comparing rates, checking delivery estimates. If you need to generate labels or book pickups, use ShipEngine's web dashboard or API directly. Switchy's agents can surface the information you need to make those decisions, but they won't execute the transaction for you. This keeps your shipping workflow auditable and prevents accidental label purchases.
How does this compare to checking tracking numbers manually?
Manual tracking means opening carrier websites, pasting numbers, and switching tabs. The MCP lets you ask "where's order 4782" in Switchy and get the answer instantly, pulling from whichever carrier ShipEngine routed it through. You also get rate comparisons across carriers in one query, which is tedious to do by hand. The trade-off: you still need ShipEngine's dashboard for label creation and account settings.
Who on the team should connect the ShipEngine MCP?
Whoever manages your ShipEngine account or has access to API keys. Once connected, any Switchy user in your workspace can query shipment data through the AI — they don't need individual ShipEngine logins. This works well for support teams who need tracking info but shouldn't have full access to create labels or change carrier settings. The API key's permissions control what data Switchy can see.
