AI product Open source
OpenAI MCP Extensions is an open-source extension framework for adding ChatGPT-specific capabilities to MCP, allowing developers to build plugins that behave as native ChatGPT features. Supported extension points include sidebar entry points, custom file-extension handlers, composer mentions for searching plugin resources and adding references to messages, and extended forms with thumbnail-based choices. The repository provides TypeScript and Python SDKs for MCP servers and Apps, along with plugin documentation and a specification. It is licensed under Apache License 2.0.
