 - MCP-compatible coding agent (e.g. [Cursor](https://cursor.com), [Claude](https://claude.ai), [Codex](https://chatgpt.com/codex/), etc.)

+- [pnpm](https://pnpm.io/) (version 11 is recommended; it is currently the most secure package manager option)
 - Git (source control tool for managing the web code your agent will produce)
 
 If you are using a chat-first tool such as Claude Desktop or ChatGPT, you can still use ProofKit to explore FileMaker metadata and data. Building Web Viewer apps requires a coding agent that can work in a project folder. See [Chat Mode vs Code Mode](/docs/ai/chat-vs-code-mode) for the difference.

+## pnpm
+
+ProofKit projects use `pnpm` for workspace installs, scripts, and monorepo tooling. We recommend **pnpm 11** because it is the fastest and most secure package manager available for the Node.js ecosystem.
+
+- Learn more: [pnpm.io](https://pnpm.io/)
+- Installation guide: [pnpm installation docs](https://pnpm.io/installation)

+After installing, verify your version:

+```sh
+pnpm -v
+```

 ## Developer background
 
 You do not need to be a web developer to get started. Familiarity with React, TypeScript, a terminal, and Git will help, but the workflow is designed so the agent does much of the setup and implementation work.
