From the repository
Install the server via uvx idea-reality-mcp, then add it to your MCP client. For example, in Claude Code run claude mcp add idea-reality -- uvx idea-reality-mcp. Then ask your agent: “Before I start building, check if this already exists: [your idea]”. The agent calls the idea_check tool with idea_text (required) and optional depth parameter ("quick" or "deep"). A REST API is also available at https://idea-reality-mcp.onrender.com/api/check with no API key required.
idea_check
Check if a product idea already exists before building it. Use when users discuss new project ideas, ask about competition, market saturation, or whether something has been built before. Trigger phrases: "has anyone built", "does this exist", "check competition", "is this idea original", "有沒有人做過", "市場上有類似的嗎", "幫我查這個點子"

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, Product Hunt, 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 — 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 6 databases in parallel (GitHub repos + stars, Hacker News discussions, npm/PyPI packages, Product Hunt launches, 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"
