CLIs, MCP servers & ChatGPT Apps

We design and build the AI tooling layer for your business — command-line interfaces for your team, MCP servers that connect your data to any AI client, and native ChatGPT Apps with interactive widget UIs.

⌨️CLI

Custom CLIs

Purpose-built command-line tools for your team's workflows. Automate reporting, deployments, data exports, and internal ops — all from the terminal.

🔌MCP

MCP Servers

Expose your CRM, database, or internal APIs as MCP tools. Any AI client — Claude, ChatGPT, Cursor — can then query and act on your data through natural language.

💬ChatGPT App

ChatGPT Apps

Native apps inside ChatGPT with interactive React widget UIs. Carousels, inline cards, data explorers — rendered directly in the conversation, not a separate tab.
