Built on the Model Context Protocol (MCP) for Claude, ChatGPT, Cursor, and more
The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.
This connection provides 13 powerful capabilities that interface natively with Claude, ChatGPT, Cursor, and other compatible AI platforms. No middleware. No custom integration required.
Dealing with shipping means switching between apps all day long., Solved with Vinkius AI Gateway
Right now, to get a quote for a package, you open Carrier A's site. You get rates. Then, if you want the cheapest option, you copy that data into a spreadsheet. If your customer gives a bad address, you have to leave the rate tool and go somewhere else just to check the zip code format. It’s manual, it takes half an hour per shipment, and you're always fighting API version changes.
With this MCP server, all that friction disappears. You tell your agent: 'Check these 10 addresses and give me the best rate for a small box.' The agent runs `validate_addresses` then `get_rates`. It gives you one clean answer, right in chat. No tabs open, no copying data—just results.
ShipEngine Alternative MCP Server: Get labels and track packages from your agent.
Before this, creating a shipment meant gathering the origin zip, destination zip, package weight, dimensions, and then manually selecting service levels to ensure you got both the rate *and* the actual label purchased. If any single parameter was wrong, the whole thing failed.
Now, you just ask your agent to 'Create a label for this shipment.' The tool handles the complex sequence: checking funds (`add_funds`), getting rates (`get_rates`), selecting the best option, and finally calling `create_label`—all in one go. It's seamless because it knows the whole workflow.
What your AI can actually do with this
This MCP Server handles your entire shipping logistics chain, letting you run complex operations through simple chat commands. Your AI client acts like an ops engineer, managing carrier accounts and fulfillment tasks without forcing you to jump between websites.
Carrier Account Management
You'll start by listing every connected account using list_carriers. If you need to connect a new provider or confirm authentication details, run connect_carrier. When you know your balances are low, you can top up funds for specific carriers with add_funds.
Address Validation and Rate Shopping
Before anything else, you've got to make sure the address is real. You validate up to 250 shipping addresses at once using validate_addresses, which confirms if the location is formatted right and deliverable. To figure out costs, you use get_rates to calculate multiple shipping quotes from different carriers based on the package size and destination zone.
For label creation that requires shopping around for deals, run create_label_rate_shopper; this tool executes rate comparison strategies so you can pick the absolute cheapest or fastest option available.
Fulfillment and Label Generation
When it's time to ship, first, you use create_shipment to generate a new shipment record using specific origin and destination details. To get the actual label purchased and generated for that package, run create_label. If you change your mind before printing, don't sweat it; void_label cancels and invalidates an existing shipping label immediately.
For large pickups, you can generate necessary carrier documents like USPS SCAN forms using create_manifest. You can also view a history of labels already generated by running list_labels.
Tracking and Status Updates
To track where the package is, you use two tools: track_package handles tracking when you provide a specific carrier code and a tracking number combination. If you only have the label ID, run track_label to check its current status in the system.

Here's how it actually works
The bottom line is you get full fulfillment control via natural language commands, treating the entire shipping stack like one chat interface.
Subscribe to the server and enter your ShipEngine API Key.
Connect the MCP Server to your preferred AI client (Claude, Cursor, etc.).
Ask your agent a logistics question—for example, 'Get rates for this address.' The agent executes the necessary tools in the background.
Who is this actually for?
E-commerce Managers and Operations Leads who are tired of toggling between Carrier websites, USPS tools, and rate comparison spreadsheets. The Logistics Developer who needs to test fulfillment workflows without writing complex boilerplate API code. If your job involves shipping anything more than once a week, you need this.
Uses the tool to compare rates for new products and generates labels in batches without manual data entry.
Manages daily shipments, validating customer addresses immediately upon receipt and tracking multiple packages simultaneously from a single chat window.
Tests complex shipping flows (e.g., rate shopping vs. fixed-rate labeling) by calling the required tools via natural language prompts instead of writing boilerplate API code.
What Changes When You Connect
You stop switching between carrier sites. The agent handles validation (validate_addresses) and rate fetching (get_rates) in one sequence before you even commit to a label.
Rate comparison is instant. Instead of checking FedEx rates on Monday and USPS rates on Tuesday, the create_label_rate_shopper tool gets all options at once, letting you choose based on price or speed.
Labeling and tracking are streamlined. You can generate labels (create_label) and immediately track them (track_package), closing out the loop without manual copy-pasting of numbers.
Account management is centralized. Use list_carriers to see what you have access to, or use add_funds right from the chat when a balance gets low—no more forgetting payments.
Data integrity stays high. Before anything else happens, running validate_addresses ensures your customer's input won't cause a costly delivery failure later on.
See it in action
The new product launch fulfillment queue
A manager receives 50 addresses for an upcoming sale. Instead of manually entering them into multiple forms, they tell their agent: 'Validate these 50 addresses and then get the best rate for a standard box.' The agent runs validate_addresses, filters the good inputs, executes get_rates on the valid set, and gives you a manifest plan.
The last-minute shipment failure
A customer calls with an old label ID. Instead of guessing if it's right, the agent runs track_label. If that fails, the manager can run void_label to clear up old records before creating a new one using create_shipment.
The billing cleanup task
You need to check your available carrier accounts. You ask the agent: 'Show me all connected carriers and check the balances.' The tool runs list_carriers, letting you see if you need to use add_funds before shipping.
The complex manifest creation
Your warehouse needs a pickup form for 20 packages. You prompt: 'Create the carrier manifest for these 20 items.' The agent uses create_manifest, generating the necessary SCAN forms directly, saving you from printing and manually filing paperwork.
The honest tradeoffs
Shipping without checking addresses first
A developer assumes an address is correct because it looks right. They run create_shipment immediately, only to fail the API call later when a carrier rejects the zip code.
Always start with validate_addresses. Run this tool on the raw customer input first. It provides the necessary guardrails before you calculate rates or create anything.
Using an outdated tracking number
A user tries to track a package using a manually copied tracking number that is missing the carrier prefix, leading to 'Invalid Number' errors.
Use track_package and provide both the specific carrier code (e.g., UPS) AND the tracking number. The tool requires both pieces of data for accurate lookup.
Ignoring label cancellation
A shipment was processed, but the customer changed their mind before pickup. The developer just deletes the record instead of calling an API function.
Use void_label. This tool correctly interacts with the carrier's system to officially void the label and prevent billing issues down the line.
When It Fits, When It Doesn't
You should use this server if your process requires multiple, sequential steps involving physical shipment: (1) Address verification (validate_addresses), (2) Cost calculation (get_rates), (3) Label generation/purchase (create_label or create_shipment), and (4) Tracking status updates. It's built for the whole pipeline.
Don't use this if you just need to store data in a spreadsheet; it is not a database tool. Also, don't use it if your primary goal is only internal communication—it’s purely focused on external carrier APIs. If you only ever validate addresses and never ship, you might be over-investing, but the full workflow capability makes it worth it.
Questions you might have
How do I validate addresses using the validate_addresses tool? +
You pass up to 250 addresses directly to the validate_addresses tool. It checks formatting and deliverability against carrier standards, telling you which ones are good to go.
Can I use get_rates to compare FedEx vs USPS rates? +
Yes. You provide the package details (dimensions, weight) and the destination zip code, and get_rates returns a comparison table of available options from multiple connected carriers.
What's the difference between create_shipment and create_label? +
Use create_shipment when you are defining the parameters for an upcoming shipment record. Use create_label when you are ready to finalize, purchase, and generate the actual physical label.
How do I track a package with track_package? +
You run track_package by providing two key pieces of info: the carrier's specific code (like UPS) and the full tracking number. This ensures accurate status retrieval.
How do I check which shipping carriers are available using the list_carriers tool? +
You first connect your API key to the server. Then, running list_carriers immediately displays all linked carrier accounts and their current status. This lets you confirm connectivity before building anything.
What is the proper procedure for voiding a label using the void_label tool? +
You must use void_label if a paid label needs to be canceled before carrier pickup. You simply supply the unique label ID, and the tool handles the cancellation request with the respective shipping provider.
What data does the create_manifest tool handle, and why is it necessary? +
The create_manifest tool requires a list of labels or shipments. Its purpose is to bundle multiple packages into carrier-specific documents (like USPS SCAN forms), making bulk pickup efficient for your logistics team.
Does the create_label_rate_shopper tool guarantee the absolute best shipping deal? +
The rate shopper compares options across multiple carriers and services in real-time. You specify what you prioritize—like 'cheapest' or 'fastest'—and it generates a label based on that optimized selection.
Can I validate multiple addresses at once to avoid shipping surcharges? +
Yes! Use the validate_addresses tool. You can provide an array of address objects, and the agent will return validation results for up to 250 addresses in a single request.
How does the AI choose the best shipping rate for me? +
You can use the create_label_rate_shopper tool with a specific strategy: 'cheapest', 'fastest', or 'best_value'. The agent will automatically compare rates across your carriers and purchase the label that fits your criteria.
Can I track a package if I only have the tracking number and carrier code? +
Absolutely. Use the track_package tool by providing the carrier_code (e.g., 'ups', 'fedex') and the tracking_number. The agent will retrieve the latest status and location updates.
