About this gig
I build custom ChatGPT Apps and MCP (Model Context Protocol) servers that connect Claude or ChatGPT directly to your data, tools, and APIs. Using the official OpenAI Apps SDK and Anthropic's MCP standard, I create production-ready integrations with custom UI widgets, multi-tool orchestration, authentication, and clean documentation.
Whether you need a lightweight single-tool MCP server or a full interactive ChatGPT App with rich UI components, I deliver scalable, secure, and well-documented solutions tailored to your business logic.
What you get:
- Custom MCP server (Python/TypeScript/Node.js)
- ChatGPT App via OpenAI Apps SDK with interactive UI widgets
- Claude Desktop / ChatGPT integration
- API & database connections
- Setup guide, docs, and deployment support
Let's turn your idea into a working AI-powered app that plugs directly into ChatGPT or Claude.

FAQ
What's the difference between an MCP server and a ChatGPT App?
An MCP server connects Claude/ChatGPT to your data and tools via function calls. A ChatGPT App (via Apps SDK) adds a full interactive UI experience inside ChatGPT, built on top of MCP.
Do you provide the source code and deployment help?
Yes, source code is included with Include Source Code add-on, and I provide deployment guidance for hosting your MCP server or ChatGPT App.
