Verified Safe

by ssssota

Overview

A framework for building type-safe ChatGPT Apps using the OpenAI Apps SDK with JSX-based UI rendering, streamlining the development and build process for Model Context Protocol (MCP) servers.

Installation

Run Command
npm create chapplin@latest (This command initializes a new Chapplin project. To run the server for the generated project, navigate to the new project directory and execute 'npm run dev'.)

Security Notes

The `chapplin` framework itself doesn't expose glaring runtime security vulnerabilities in its core logic, relying on established server (Hono, Express) and build (Vite, Rollup) technologies. The build process involves parsing and transforming developer-provided code (e.g., JSX components into HTML widgets), which is a common pattern in build tools but carries inherent risks if not handled securely or if underlying dependencies have flaws. No direct use of `eval` or hardcoded secrets found within the provided source code for the framework's runtime. Environment variables like `OPENAI_API_KEY` would be critical for applications built with `chapplin` to interact with OpenAI services, but are not directly required by the framework's core to function.
