# idea-reality-mcp
**How to check if someone already built your app idea — automatically.**
idea-reality-mcp is an MCP server that scans GitHub, npm, PyPI, Hacker News, and Stack Overflow to check if your startup idea already exists. It returns a 0–100 reality score with evidence, trend detection, and pivot suggestions — so your AI agent can decide whether to build, pivot, or kill the idea before writing any code.
**When to use this:** You're about to start a new project and want to know if similar tools already exist, how competitive the space is, and whether the market is growing or declining.
> **Not just checking — building it?** After a reality check, open your idea as a public project on **[AngelRun](https://angelrun.vercel.app/new?utm_source=idea-reality&utm_medium=readme&utm_campaign=demand-cta)** — ship updates, climb the season, and get seen by angels.

## How it works
1. **Describe your idea** in plain English — e.g. "a CLI tool that converts Figma designs to React components"
2. **idea_check scans 5 databases** in parallel (GitHub repos + stars, Hacker News discussions, npm/PyPI packages, Stack Overflow questions)
3. **Get a 0–100 reality score** with trend direction (accelerating/stable/declining), top competitors, and AI-generated pivot suggestions
## What you get
```
You: "AI code review tool"

```
One score. Six sources. Trend detection. Your agent decides what to do next.

## Quick Start
```bash
# 1. Install
uvx idea-reality-mcp
# 2. Add to your agent
claude mcp add idea-reality -- uvx idea-reality-mcp # Claude Code
```
**3. Ask your agent:** *"Before I start building, check if this already exists: a CLI tool that converts Figma designs to React components"*
That's it. The agent calls `idea_check` and returns: reality_signal, top competitors, and pivot suggestions.
