Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Launch Engine

npm version License: MIT GitHub stars

Agentic Business Pipeline OS as an MCP server. Full pipeline from idea to revenue — for solo founders and bootstrappers.

npx -y launch-engine-mcp

Launch Engine Demo


Why Launch Engine?

Most MCP servers give you one tool. A GitHub integration. A database query. A Slack bot.

Launch Engine gives you 39 tools that work as a pipeline — the entire playbook from raw idea to validated revenue, running inside the AI client you already use.

  • No more blank-page paralysis. Start with scout and the system tells you exactly what to do next, every step of the way.
  • Every stage feeds the next. Buyer research flows into offer design. Offer design flows into campaign copy. Campaign copy flows into validation. Nothing is wasted.
  • Math before assets. Unit economics are validated before you build anything. You'll never spend weeks building an offer that can't work at your budget.
  • Test ideas for $50, not $5,000. rapid_test gives you signal in 3-5 days with a landing page and paid traffic — before you commit to the full pipeline.
  • Your AI becomes a co-founder, not a chatbot. It doesn't just answer questions. It executes a structured business system with you.

Install

npm install -g launch-engine-mcp

Or run directly without installing:

npx -y launch-engine-mcp

Quick Start

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "launch-engine": {
      "command": "npx",
      "args": ["-y", "launch-engine-mcp"],
      "env": {
        "LAUNCH_ENGINE_PROJECT_DIR": "/path/to/your/project"
      }
    }
  }
}

Cursor

Add to your MCP settings (.cursor/mcp.json):

{
  "mcpServers": {
    "launch-engine": {
      "command": "npx",
      "args": ["-y", "launch-engine-mcp"],
      "env": {
        "LAUNCH_ENGINE_PROJECT_DIR": "/path/to/your/project"
      }
    }
  }
}

From Source

git clone https://github.com/ZionHopkins/launch-engine-mcp.git
cd launch-engine-mcp
npm install
npm run build
node dist/index.js

How It Works

Launch Engine is a two-layer tool system:

Layer A — 39 SOP Tools (read-only): Each tool validates prerequisites against pipeline-state.json, loads upstream context from previous stages, checks learnings.json for patterns, and returns full SOP instructions enriched with that context. Your AI executes the instructions.

Layer B — 3 Utility Tools (mutations): update_pipeline_state, save_asset, capture_learning. These handle all state writes and file creation. Your AI calls them after executing each SOP.

The Pipeline

Four entry points:

1. scout        → Full pipeline (research → offer → build → deploy → validate)
2. rapid_test   → Quick $50-100 test (signal in 3-5 days)
3. passive_deploy → Marketplace assets (after research)
4. tournament   → Batch-evaluate 3-5 ideas through Layer 1 simultaneously

Full Pipeline Flow

LAYER 1 (Strategist):
  scout → autonomy → market_intel → research → build_blocks → stress_test → unit_economics

LAYER 2 (Builder):
  name_lock → platform + product → deploy → qa → validate_prep

LAYER 3 (Validator):
  validate_check (daily) → validate_decide → feedback → iterate

TRAFFIC (Paid):
  traffic_strategy → channels → creative_test → funnel_optimize → scale

ORGANIC GROWTH (runs parallel with paid):
  content_engine → content_repurpose → seo_check (monthly)

CROSS-CUTTING:
  status | daily_check | lessons | voice_extract | dream_100 | tournament

Each tool checks prerequisites automatically. If you try to run research before completing market_intel, you'll get a clear STAGE_BLOCKED message telling you exactly what to run first.

Configuration

The project directory is resolved in order:

  1. LAUNCH_ENGINE_PROJECT_DIR environment variable
  2. --project-dir= CLI argument
  3. Current working directory

First Use

When you run status with no existing pipeline, you'll see:

Three paths available:

  1. rapid_test — $50-100 paid traffic test in 3-5 days
  2. scout — Full active pipeline with deep research and validation
  3. passive_deploy — Marketplace assets (requires research first)

Best Practices

Getting Started

  • Start with status — always run this first. It reads your pipeline state and tells you exactly where you are and what to do next.
  • New idea? Use rapid_test first — don't run the full pipeline on an unvalidated idea. Spend $50-100 to get signal in 3-5 days. If it graduates, then run scout.
  • One pipeline at a time — you can run multiple rapid tests in parallel, but focus on one full pipeline at a time. Context switching kills momentum.

During the Pipeline

  • Follow the order — the prerequisite system exists for a reason. Each stage feeds the next. Skipping market_intel means research has no competitive context. Skipping stress_test means you might build assets for a broken offer.
  • Don't skip qa — it catches promise-product misalignment, unattributed statistics, and persona drift. Every asset that touches a buyer must clear the QA gate.
  • Run daily_check every day during validation — it takes 60 seconds and catches problems before they burn budget.
  • Use lessons after every major decision — verdicts (ADVANCE/KILL), graduated rapid tests, creative test winners. The pattern library makes every future pipeline smarter.

Working with the AI

  • Let the AI execute the full SOP — each tool returns complete instructions. Don't interrupt midway. Let it finish the research, generate the deliverables, and save the files.
  • Review Tier 3/4 decisions carefully — the system will pause and ask for your input on market selection, pricing, kill decisions, and anything involving real money. These pauses are intentional.
  • Trust the mathunit_economics will tell you if the numbers work at your budget. If the verdict is NON-VIABLE, don't try to force it. Move on or adjust the offer.

Scaling

  • Validate before you scalescale requires proven creative winners with 30+ conversions. Scaling unvalidated campaigns is the fastest way to burn money.
  • Compound your learnings — passive assets that reach ANCHOR status should trigger passive_compound. One proven asset can spawn 5-10 related assets.
  • Run traffic_analytics weekly — attribution drift happens. What worked last week may not work next week. Stay on top of the data.

Common Mistakes to Avoid

  • Don't build assets before stress_test passes — a GO verdict means the offer is structurally sound. REVISE or REBUILD means fix the foundation first.
  • Don't skip name_lock — changing the business name after assets are built means rebuilding everything. Lock it early.
  • Don't ignore KILL signals — if rapid test metrics hit kill thresholds, kill it. If validation says KILL, capture the lessons and move on. Sunk cost is not a strategy.
  • Don't publish without qa clearance — unvetted copy with unattributed claims or persona misalignment damages trust and conversion rates.
  • Don't run the full pipeline for every idea — that's what rapid_test is for. Test 5-10 ideas cheaply, then invest the full pipeline in the winner.

Automated QA Test Suite (New in v1.1.0)

The pipeline includes an automated QA test suite that runs at 3 points:

| Gate | When | What It Catches | |------|------|----------------| | Pre-Deploy | Before deploy generates assets | Missing research, broken unit economics math, placeholder text | | Post-Deploy | After assets written, before qa | HTML issues, exposed API keys, email subject length, missing CTAs | | Post-QA | After persona corrections | Structural issues introduced by corrections |

Test modules in qa-tests/:

  • test_landing_page.py — HTML structure, CTA presence, secret detection
  • test_campaign_assets.py — Email/ad validation, brand consistency
  • test_research_report.py — Section completeness, citation density, contradiction detection
  • test_unit_economics.py — Margin positivity, CAC/LTV ratio, math verification

Requires: Python 3.10+
