the-stack
The real 19Keys tool stack — forensically inventoried straight off the machine (brew formulae, brew casks, /Applications, npm globals, Claude skills, cloned external repos, MCP servers, Ollama models). Not a listicle of "tools I heard about." This is what is actually installed and actually gets used.
The philosophy underneath it: build, don't spend. Own the machine. Self-host what you can. Reach for an open-source or local tool before a subscription. Where a paid or hosted service is genuinely the right call (Vercel, Supabase, Cloudflare), it's here too — sovereignty means choosing your dependencies on purpose, not avoiding them on principle.
Every entry below links to the tool's official site or canonical repo. Install commands are given where there's a real one-liner.

MCP servers & agent infrastructure
MCP (Model Context Protocol) is the open standard that lets an AI agent call out to external tools and data sources — it's how Claude Code (or any MCP-compatible client) gets hands on a filesystem, a database, a design tool, or a browser instead of just talking.
| Server | What it connects the agent to |
|---|---|
| Desktop Commander | Filesystem, process, and terminal control on the local machine |
| Engram memory — see engram above | Persistent memory across agent sessions |
| Figma MCP | Reads design files, components, and variables directly from Figma |
| Supabase MCP | Runs migrations, queries, and project admin against a Supabase project |
| ElevenLabs | Text-to-speech, voice cloning, sound effects generation |
| Shopify | Store, product, and order operations against a Shopify shop |
| Gamma | Generates and edits slide decks and documents |
| Webflow | Reads and edits Webflow site structure, CMS, and styles |
| Playwright-based browser tools — see Playwright | Drives a real browser: navigate, click, read page content, screenshot |

Start here
New to this stack and don't know where to begin? Install these five first, in this order:
- git — version control, the foundation everything else sits on
- A real terminal setup — see /terminal-setup on this archive
- Claude Code — the AI coding agent this whole workflow is built around
- Ollama — local AI, no API key needed — see /local-ai-setup
- Obsidian — your second brain — see /obsidian-second-brain
Everything else in this table is optional, situational, or swap-in-later. These five are not.
