ToolJet claims its MCP-based workflow lets Claude Code and Codex build internal tools more practically than the bespoke multi-agent application generator the company abandoned after eleven months of development.

What is this?

ToolJet is an open-source platform for building internal tools, dashboards, business applications, workflows, and AI agents. Its launch announcement claims a new MCP interface lets agents such as Claude Code, Codex, and Cursor create and inspect ToolJet applications, positioning existing coding agents as a more practical approach than ToolJet’s reportedly abandoned bespoke multi-agent generator. The supplied web snippets do not independently establish the eleven-month development history, the abandonment details, or comparative performance, so those remain ToolJet’s claims rather than verified findings.

Why it matters to Scott

ToolJet’s claimed eleven-month pivot is a strong external receipt for Scott’s build-versus-integrate position: use established coding agents as bounded execution backends and preserve the application as structured, editable state rather than building a bespoke multi-agent generator. It also closely parallels his Claude Code-operated products and AI-editable-schema pattern, although ToolJet’s development history and comparative results remain unverified claims.

🟠 redditWe scrapped our own agents and instead exposed our 5yo no-code platform to Claude Code via MCP. Goal was to generate no-code apps. Here is a video of Claude Code assembling an entire app and testing in browser within 25 mins. Spent 11 months building own agents that didn't do a good job.
