lightweightindustries\n\nThe public website at **lightweightindustries.com**, plus the backend behind it.\n\nContent is authored as markdown and rendered to HTML on the server. There is no client-side\nframework and no build step — a request comes in, a markdown file is read, and finished HTML\ngoes out.\n\n---\n\n## The website\n\n**A page is a markdown file.** `content/home.md` is the home page.\n\nThe block at the top of the file, between the `---` lines, is the frontmatter. It sets the\nbrowser tab title and the description search engines show:\n\n```markdown\n---\ntitle: Lightweight Industries\ndescription: Small, sharp software for people who'd rather own their tools.\n---\n\nEverything below the frontmatter is the page body, written as ordinary markdown.\n```\n\n**Adding a page is adding a file.** Dropping in `content/about.md` serves it at `/about` with\nno code change. An unknown slug returns a real 404.\n\nPages are server-rendered on purpose rather than assembled in the browser: a marketing site\nneeds to be crawlable by search engines and to paint immediately, and neither is true of a\nJavaScript app that fetches its own content after loading.\n\n### Other routes\n\n| Route | What it does |\n| --- | --- |\n| `/` | the home page |\n| `/` | the page in `content/.md` |\n| `/source` | redirects to this val's code |\n| `/auth/reset` | clears the unlock cookie (see below) |\n| `/api/unlock` | receives the email form |\n| `/auth/google/callback` | receives Google's sign-in POST |\n| `/mcp` | the MCP server (see below) |\n\n---\n\n## Gates\n\nA gate trades a visitor's identity for something you don't give away for free. The site ships\nwith one: your booking calendar.\n\n### How it works\n\nA gate is **a content file plus a token**. Its frontmatter holds every word the gate says\nwhile it is locked; its body is what a visitor gets once it opens:\n\n```markdown\n---\nprompt: Let me know who's asking and I'll show you my calendar.\nbutton: Show me the calendar\nfallback: Use your email instead\n---\n\n\n```\n\n| Key | Where it shows | If you leave it out |\n| --- | --- | --- |\n| `prompt` | the line above the Google button | a plain generic sentence |\n| `button` | the email form's submit button | \"Continue\" |\n| `fallback` | the summary on the collapsed email form | \"Use your email instead\" |\n| `assurance` | a small line under the form | **nothing at all** — the line simply doesn't exist |\n\n**No visitor-facing copy lives in the code.** That is deliberate: a second gate offering\nsomething other than a calendar writes its own words instead of inheriting these. `assurance`\nhaving no default is part of the same idea — a gate should be able to say less, not just\nsay something different.\n\nA page opts in by putting the matching token on a line of its own:\n\n```markdown\n## Availability\n\n{{gate:calendar}}\n```\n\nThe server replaces that token with one of two things.\n\n**If the visitor hasn't identified themselves,** they get the prompt, a **Continue with\nGoogle** button, and a collapsed disclosure hiding a plain email form.\n\n**If they have,** they get a line reading *\"Continuing as name@example.com · (Not you?)\"*\nand then the reward. The identity line comes first on purpose — it says whose view this is\nbefore handing over what was unlocked, rather than trailing after a 600px embed.\n\n### What happens in between\n\n- **The Google path** (the default) opens Google's own account chooser in a popup. It returns\n a **verified** address along with the visitor's given name, family name, and company domain.\n- **The email form** (the fallback) captures whatever they type. It is not verified.\n\nEither way the address is written to a Notion database, and a cookie records that this\nvisitor has already paid the toll so they are never asked twice.\n\n### Adding a second gate\n\nCreate `content/gates/.md` and put `{{gate:}}` on its own line in a page.\n**That's the whole procedure — adding a gate is never a code change.**\n\n### Two deliberate decisions worth knowing\n\n**The unlock cookie is unsigned.** Forging it reveals a calendar link that is handed to\nanyone who signs in, so signing the cookie would buy nothing. It is not a security boundary.\nIf a gate is ever put in front of something genuinely valuable, that decision has to be\nrevisited.\n\n**The cookie lasts a year and is `httpOnly`,** which means that without an escape hatch\nnobody — the author included — could ever see their own gate again after opening it once.\nThat is what `/auth/reset` and the \"not you?\" link are for.\n\n---\n\n## The MCP server\n\nAn [MCP](https://modelcontextprotocol.io) server lets an AI assistant call specific functions\nyou have defined, instead of poking at the site blindly. This one is mounted at `/mcp` and\nspeaks streamable HTTP.\n\n| Tool | What it does |\n| --- | --- |\n| `list_content` | Lists the page slugs and gate names the site is made of |\n| `read_content` | Returns one page or gate as raw markdown, frontmatter intact |\n\nBoth are read-only.\n\nIt is built on `@modelcontextprotocol/server@2` — the v2 TypeScript SDK, compatible with the\n2026-07-28 MCP spec and still serving older clients — which is the shape Val Town's own\n`templates/mcp-server` uses.\n\n### Protecting it\n\nMost Val Town MCP servers are protected by making the whole val private, letting the platform\nedge turn away anyone without a bypass token. **That is not available here**, because this val\nserves a public website. So `/mcp` checks a secret of its own:\n\n```\nAuthorization: Bearer \n```\n\nIt **fails closed** — if `MCP_TOKEN` is not set, every request is refused rather than allowed\nthrough. While the val's HTTP privacy is still `restricted`, a client needs the platform's\n`X-Val-Town-Access` header *as well*; once the val is public, the bearer token is the only\nthing standing in front of the tools.\n\n### Connecting a client\n\n```json\n{\n \"mcpServers\": {\n \"lightweightindustries\": {\n \"type\": \"http\",\n \"url\": \"https://lightweightindustries.val.run/mcp\",\n \"headers\": {\n \"Authorization\": \"Bearer \"\n }\n }\n }\n}\n```\n\nMCP clients cache the tool list per session, so a newly added or renamed tool only appears\nafter the client reconnects. Tool *behavior* is always live.\n\n---\n\n## Environment variables\n\nNone of these are required for the site to serve pages. Each one missing degrades a feature\nrather than breaking the site.\n\n| Variable | Powers | If it is missing |\n| --- | --- | --- |\n| `GOOGLE_CLIENT_ID` | the Continue with Google button | the button renders disabled and visibly names the variable, rather than vanishing — a missing button reads as a bug |\n| `NOTION_API_KEY` | recording registrations in Notion | the gate still unlocks; the address is logged, not recorded |\n| `REGISTRATIONS_DATABASE_ID` | which Notion database receives them | same as above |\n| `MCP_TOKEN` | the `/mcp` guard | `/mcp` refuses every request |\n\nThere is no Google client *secret*. The sign-in flow is Google Identity Services, which\nhappens in the browser and has no code exchange, so no secret exists to store.\n\n### The registrations database\n\nEvery unlock writes one row. It is an **append-only event log** — nothing is ever read back or\nupdated, so the same person registering twice produces two rows. That is intended: events are\nthe lossless record, and a deduplicated view of *people* is a separate, derived thing best\nbuilt later against real data. Keeping this write-only is also what stops an unverified typed\nsubmission from ever mutating a row that Google verified.\n\nThe Notion integration must be **shared with the database** in Notion's own UI. The schema the\ncode writes:\n\n| Property | Type | Notes |\n| --- | --- | --- |\n| `Name` | title | display name from Google, or the address when there isn't one |\n| `Email` | email | |\n| `Given name`, `Family name`, `Domain` | text | Google path only; blank for typed submissions |\n| `Gate` | select | which gate they opened |\n| `Source` | select | `google` or `typed` — **the column that says how much to trust the address** |\n\n`Created time` is Notion's own, and it is the event timestamp.\n\n---\n\n## Architecture\n\nThree layers, no shortcuts between them:\n\n```\nrequest → route → controller → service → outside world\n```\n\n- **Routes** (`backend/routes/`) extract what the request carries and return a response. No\n decisions.\n- **Controllers** (`backend/controllers/`) validate, decide, and orchestrate. They return a\n plain result object, never an HTTP response — which is exactly what lets the MCP tools call\n the same functions the web pages use, with no route in front.\n- **Services** (`backend/services/`) talk to the outside world — files, Notion, Google. They\n never throw; every failure comes back as a value.\n\n`backend/utils/` holds pure backend helpers, and `shared/` holds code safe for both the server\nand a browser.\n\n**`content.service.ts` is the seam.** Content is files today, but every read goes through that\none service — so moving content to Notion or a CMS later changes that file and nothing else.\n\n```\nbackend/\n index.http.ts entry — mounts the routes\n routes/ pages, api, auth, mcp\n controllers/ page (renders), content (reads source), gate\n services/ content, notion, google.oauth, blob\n utils/ frontmatter, markdown, layout, html, gate, slug\ncontent/\n home.md a page\n gates/calendar.md a gate\nshared/ types + the result helper, browser-safe\n```\n","children",[],[250],"2eace418-7434-4751-aa7a-7a91320b5ad9","response.ts","495bab08-ac3f-11f1-8027-1607ee4eb77e","01a085de-26c9-705c-866d-b894979a2c42",["D",1788952323787],"import type { ServiceResponse } from \"./types/index.ts\";\n\nexport function createSuccessResponse(data: T): ServiceResponse {\n return { success: true, data };\n}\n\nexport function createErrorResponse(\n error: string,\n status = 500,\n): ServiceResponse {\n return { success: false, error, status };\n}\n",[],[265,258],"shared","8a8abe52-a94a-4397-b830-720416c69752","index.ts","495bb0b2-ac3f-11f1-8027-1607ee4eb77e","01a085de-26c9-705c-866d-be21fdb6784a",["D",1788952323787],"/**\n * Contracts that cross the layer boundary.\n *\n * Pure types only — `shared/` must stay browser-safe, so nothing here may\n * import a Deno API.\n */\n\n/** Every controller and service returns this.

\n\n_Video: publishing Notion charts of Salesforce data from Slack_\n\n---\n\nBy the way, I know _Notionizer_ is an awful name. I needed a working title.\n\nI needed a working title because I can't share the real thing, which is running\nmy client's Salesforce data inside their Notion and Val Town accounts.\n\nAs for the demo, it works with Salesforce's developer sandbox data and runs out\nof _my_ Notion and Val Town accounts.\n\n---\n\n`Features`\n\nIt's satisfying to be able to bring rich, accurate detail about a business into\nthe context of a conversation. For many of us, Slack is where most of those\nconversations happen, or could happen. And as for Notion, to me, Notion is _the\nbest good enough workspace_ and it's perfect for artifacts like these reports.\n\n![slack-notion-line-chart.png](https://imagedelivery.net/iHX6Ovru0O7AjmyT5yZRoA/b49ce85f-e306-4b4c-d695-324332c7a900/public)\n\n_Screenshot: Slack and Notion, side by side_\n\nSome other features that may not be obvious but are worth a beat:\n\n- **Ready access**: Anyone in the company who can use Slack and who has access\n to Notion can publish and view Salesforce data.\n- **Speed**: Val Town syncs Salesforce data to Notion in the background, so\n publishing charts and tables is fast.\n- **No artifact sprawl**: Reports are saved as pages of a Notion database, not\n strewn around the workspace or marooned in another tool.\n- **Reusability**: Reports are generated from simple Markdown templates, with\n user- and agent-friendly prompts that render in Notion as charts and tables.\n- **Presentability**: Notion's `Present` mode (beta) isn't exactly a PPT or\n Slides killer but it is good enough to run a standup from and it is\n immediate—you can go from Slack to a Notion report to a data-driven\n presentation without any pixel pushing or\n [copypasta](https://www.dictionary.com/culture/slang/copypasta).\n\n![markdown-prompt-line-chart.png](https://imagedelivery.net/iHX6Ovru0O7AjmyT5yZRoA/83153119-c7f0-40bc-d49e-9a95988a4d00/public)\n\n_Screenshot: a Notion line chart with a reference line set from Slack_\n\n---\n\n`Goals`\n\n## More transparency, more efficiently achieved\n\nTime and cost savings are measurable but other goals—no less worthy!—drive this\nwork, too.\n\n### A clear picture of pipeline\n\nNotion charts do a good job of telling the highest-value story. They are not a\nreplacement for tools like Looker or Jupyter data science notebooks but if what\nyou need are clear pictures of data that is otherwise out of reach in tools like\nthose, they're great.\n\n![CleanShot 2026-09-12 at 7.39.38 AM.png](https://imagedelivery.net/iHX6Ovru0O7AjmyT5yZRoA/d437a2ac-f6ee-45eb-2efa-cb6d15dab000/public)\n\n_Screenshot: a Notion donut chart and table view of open deals_\n\n### Fewer subscriptions / seats\n\nThe time was right —\n[Salesforce had recently gone headless](https://www.linkedin.com/posts/boxaaron_the-big-news-this-week-in-software-was-salesforces-share-7451336945659535362-QNZw/),\nwhich made room for a new way of thinking about subscription expenses and\naccess. With the Salesforce data out of Salesforce and synced to Notion, fewer\npeople need seats for Salesforce, and everyone (and everything) can access the\ndata where they work.\n\n### Faster, all the time\n\nTo click a button in Slack and publish a report filled with live charts and\ntables in Notion is fun. But more imoportantly, it's how my client saves ~3\nhours every Sunday night preparing for a Monday morning meeting with his team.\nHe used to dig through Salesforce and cut and paste data into Trello\nthat would go stale immediately, and then have to do it again the following\nweek.\n\n### Tighter feedback loops\n\nWith the pipeline data at everyone's finger tips, Slack conversations can be\ndata informed, without delay. We don't need a meeting. There's no need to carve\nout time to prep the data. We have it, right here:\n\n![CleanShot 2026-09-12 at 8.07.00 AM.png](https://imagedelivery.net/iHX6Ovru0O7AjmyT5yZRoA/20b0514d-30be-4b8a-df69-8bfb77e4a800/public)\n\n_Screenshot: the /notionizer slash command and prompt that publishes pipeline\nreports in Notion_\n\n---\n\n`Technology`\n\n### Claude Max and friends\n\nThere's a lot more that I can and probably should say about each of these bits;\nespecially Val Town, which is a non-negotiable for me the last few years.\n\n- A [Slack slash app](https://docs.slack.dev/app-manifests/)\n- [Notion](https://www.notion.com/),\n [Notion's API](https://developers.notion.com/guides/get-started/overview), and\n [Notion's Javascript SDK](https://github.com/makenotion/notion-sdk-js), out of\n the box\n- The [Salesforce API](https://developer.salesforce.com/free-trials), for\n Opportunities and Accounts data\n- [Val Town](https://www.val.town/) syncs Salesforce data to Notion, hosts and\n secures the API, stores Markdown, and writes everything to Notion\n- [Val Town's MCP plugin](https://docs.val.town/guides/prompting/plugin) pushes\n code live ~instantly (no local code!)\n- [Anthropic's API](https://platform.claude.com/) publishes Markdown prompts as\n charts and tables in Notion (running Haiku — cheap!)\n- I wrote ~all the code with\n [Claude Code (Max)](https://support.claude.com/en/articles/11049741-what-is-the-max-plan)\n\n",[],[194,295],"74c4de13-ab75-461b-897b-e41df00cc37d","leadfeeder.md","199464b2-aebc-11f1-a8b0-1607ee4eb77e",["D",1789409322137],14,"---\ntitle: Mission work - Lightweight Industries\ndescription: Consolidating 3 missions into one.\n---\n\n# Leadfeeder\n\nConsolidating three missions into one.\n\n---\n\nAs for the demo, it works with Salesforce's developer sandbox data and runs out\nof _my_ Notion and Val Town accounts.\n\n---\n\n`Background`\n\n## favicon\n\n![lightweight-logo-linkedin-400.png](https://imagedelivery.net/iHX6Ovru0O7AjmyT5yZRoA/b9a80cb1-d37a-432e-0f1a-c89b682f3900/public)\n![favicon-bold.png](https://imagedelivery.net/iHX6Ovru0O7AjmyT5yZRoA/d373850d-064e-412b-4a6d-359991690c00/public)\n\n## lockup\n\n## svg as code\n\n\n\n\n\n\n## .svg\n\n![lightweight-logo.svg](https://imagedelivery.net/iHX6Ovru0O7AjmyT5yZRoA/c3126909-6982-47d1-67e7-85817b382700/public)",[],[194,304],"243e76a8-a1de-43ed-8e2e-09b95e9f0fe7","home.md","495ba220-ac3f-11f1-8027-1607ee4eb77e",311,["D",1789388309435],49,"---\ntitle: Lightweight Industries\ndescription: Messaging and tools for CEOs choosing what travels.\n---\n\n# Messaging and tools that travel.\n\n---\n\n`Recently`\n\n## [“No more pipeline gatekeeping” — Notion charts of Salesforce data, right from Slack](/notionizer)\n\n\n\n---\n\n`About`\n\n## Lightweight is a messaging and tools business.\n\nRun by Brad Noble, Lightweight is for CEOs and founders choosing carefully the\nwords and tools to carry on the journey ahead.\n\n
