eBay Developer Program Compliance

# eBay Developer Program Compliance

This document outlines how the ebay-mcp-remote-edition project complies with eBay's developer policies and open source best practices.

## Project Classification

**This is an INDEPENDENT third-party open source project**, not an official eBay project. It uses eBay's public APIs and is developed by independent contributors.

- **NOT** an official eBay project
- **NOT** developed by eBay employees
- **NOT** affiliated with, endorsed by, or sponsored by eBay Inc.
- Uses eBay's public APIs under their Developer Program Terms

## eBay Open Source Policy Compliance

### License Status ✅

**Current License:** MIT License

According to [eBay's Open Source Licensing Policy](https://opensource.ebay.com/licenses/):

|--------------|--------|-------|
| **MIT** | ✅ GREEN | Approved for use without OSPO review |
| Apache 2.0 | ✅ GREEN | eBay's preferred outbound license |
| BSD-2 | ✅ GREEN | Also acceptable |

**Our Choice:** MIT is on eBay's "green" list of acceptable licenses, meaning it can be used without approval from eBay's Open Source Program Office (OSPO).

**Note:** While eBay prefers Apache 2.0 for their own projects, MIT is equally acceptable for independent projects and provides:
- Simple, permissive licensing
- Wide community acceptance
- Clear liability disclaimers
- Easy to understand for contributors
