About USPS Developer Portal MCP Server
Empower your AI agent to orchestrate your entire postal logistics and address auditing workflow with the USPS Developer Portal, the official source for United States Postal Service data. By connecting USPS Web Tools to your agent, you transform complex shipping tasks into a natural conversation. Your agent can instantly verify addresses, audit package tracking statuses, and retrieve ZIP code metadata without you ever touching a shipping portal. Whether you are managing e-commerce deliveries or conducting regional address audits, your agent acts as a real-time logistics consultant, ensuring your data is always verified and precise.
GitHub Copilot Agent mode brings USPS Developer Portal data directly into your VS Code workflow. With a project-scoped config, the entire team shares access to 8 tools — Copilot queries live data, generates typed code, and writes tests from actual API responses, all without leaving the editor.
What you can do
- Address Auditing — Standardize and verify United States addresses to ensure your shipping metadata is always grounded in official USPS records.
- Advanced Tracking Control — Track real-time package statuses and access granular facility-level tracking events instantly.
- ZIP Code & Routing Discovery — Cross-reference ZIP codes with city/state pairs to understand the geographic reach of your logistics.
- Domestic & International Rates — Accurately calculate the real-time cost of shipping across various mail classes, weights, and global destinations.
- Service Delays & Commitments — Query live delivery commitments by mail class to accurately orchestrate e-commerce fulfillment.
