AI co-founder MCP server for solo founders
Callout
You used AI to write code for 3 days. Callout tells you 60% of it was over-engineered.
AI coding tools make you 10x faster at writing code. Nobody checks if you're building the right thing. Callout is the second pair of eyes — 9 expert perspectives that catch what you miss, delivered as an MCP server that works inside Claude Code, Cursor, VS Code, and Windsurf.
Why Callout exists
A real product was built using Claude Code in 6 days: 186 files, 691 tests. A multi-perspective review on Day 5 found that 60% was over-engineered. 9 days of planned work reduced to 3.5 days. The key insight: the problem wasn't bad code — it was wrong priorities and missed blind spots.
Callout makes that review available to every developer, automatically.
30-second setup
npx callout-dev setup
No global install needed. Run this from your project directory. Callout auto-detects your editor and configures the MCP server.
After setup, restart your editor (or re-enter Claude Code from the project directory), then say:
Review this project
Manual setup (if npx setup doesn't work)
Claude Code:
claude mcp add callout -- npx callout-dev
Cursor / VS Code — add to your editor's MCP config (.cursor/mcp.json or .vscode/mcp.json):
{
"mcpServers": {
"callout": {
"command": "npx",
"args": ["callout-dev"]
}
}
}
Windsurf — add to ~/.codeium/windsurf/mcp_config.json with the same format.
After any manual setup, restart your editor so it picks up the new MCP server.
Quick Start: What to say
| Phase | What you want | Say this to AI | What happens |
|---|---|---|---|
| Get started | Check my AI collaboration habits | "Coach me" | Scans your project setup, finds blind spots, outputs improvement checklist |
| Evaluate this project | "Review this project" | 9 expert perspectives review your project, categorize as MUST FIX / SHOULD FIX / GOOD | |
| Is this idea worth building? | "Score this idea" | 10-dimension scoring, verdict: CONTINUE / SIMPLIFY / PAUSE / DELETE | |
| Go deeper | Get advice on a specific decision | "Review focus: should I use Supabase?" | Multi-perspective review focused on one question |
| Make AI read docs before coding | "Bind Stripe docs to payment code" | AI must read official docs before modifying protected files — no more guessing | |
| What tool should I use? | "I need to add payments" | Detects project needs, recommends best tool with install steps | |
| Manage | See all findings and progress | "Show my todos" | All review/coach findings auto-collected, sorted by priority |
Multi-project? Say "portfolio" for cross-project health status and resource allocation advice.
Core Features
`review` — 9 expert perspectives on your project
3 groups, 9 perspectives:
| Group | Perspectives | What they catch |
|---|---|---|
| Technical | CTO, Security, DevOps | Over-engineering, vulnerabilities, deployment gaps |
| Business | Product, Customer, Strategy | Missing features, UX gaps, business model issues |
| Founder | Investor, Unicorn Founder, Solo Entrepreneur | Market fit, scalability, solo feasibility |
Every finding is categorized as MUST FIX, SHOULD FIX, or GOOD with effort estimates. Starts with an Executive Summary.
> Review this project — full 9-perspective review
> Review with founder group — investor + unicorn founder + solo entrepreneur
> Review focus: should I use Supabase or Firebase? — focused on one decision
> Review security + CTO only — selected perspectives
`coach` — AI collaboration blind spot detector
Analyzes your project setup, development habits, and knowledge gaps. Tells you what you don't know you're doing wrong when working with AI coding tools.
`idea_score` — Quantitative idea validator
Scores your idea across 10 dimensions (market size, feasibility, moat, revenue potential, etc.) with a skeptical default stance. Returns a verdict: CONTINUE, SIMPLIFY, PAUSE, or DELETE.
Domain Knowledge Guard — Make AI read docs before coding
Bind official documentation to code paths. Once bound, AI must read the referenced docs before modifying protected files.
> Bind Stripe docs to payment code — register a doc binding
> Check if my code matches the docs — compliance verification
> Start a renovation for stripe — systematic domain knowledge audit
