PostEx MCP Server

PostEx MCP Server

The PostEx MCP Server bridges AI assistants with the PostEx Merchant API, allowing developers to expose a rich set of shipping‑related tools directly through the Model Context Protocol. By running this server, an AI can query PostEx for operational cities, create or list orders, track shipments, and manage pickup addresses—all without needing to write custom API wrappers. This eliminates boilerplate code and streamlines the integration of shipping workflows into conversational agents or automated support systems.

The server listens on standard I/O, a common MCP convention, and authenticates with PostEx using an API token supplied on launch. It then registers a collection of tools that map one‑to‑one to the merchant API’s endpoints. Each tool is defined with clear input schemas (validated by zod) and a concise description, ensuring that AI assistants can invoke them with confidence. For example, accepts order details and returns a tracking number, while lets an assistant fetch status for multiple parcels in a single call. The server also exposes utility tools such as and , giving agents quick access to contextual information about the merchant’s shipping footprint.

Key capabilities include:

• Address management (, ) to keep pickup locations up‑to‑date.
• Order lifecycle operations (, , ) that cover creation, monitoring, and cancellation.
• Tracking services (, ) for real‑time visibility of shipments.
• Shipper advice handling (, ) to record and retrieve post‑delivery guidance.
• Status & payment queries (, ) to reconcile orders with financial records.

In practice, a customer‑support AI can answer questions like “What is the status of my order #12345?” by invoking , or a logistics bot can automatically schedule pickups by calling followed by . The server’s design also supports batch operations, making it suitable for integration into high‑volume e‑commerce platforms that need to process hundreds of orders per day. By abstracting the intricacies of HTTP authentication, request formatting, and error handling, the PostEx MCP Server empowers developers to focus on building intelligent workflows rather than plumbing.
