Idea Reality Mcp
Before you spin up a new side project, this server scans GitHub, Hacker News, npm, PyPI, Product Hunt, and Stack Overflow to check if someone already built it. It exposes a single tool, idea_check, that takes your plain English description and returns a 0-100 reality score with trend direction, top competitors by stars, and pivot suggestions. Quick mode hits GitHub and HN in under three seconds. Deep mode adds the package registries and community sites for a fuller picture. The scoring engine weighs repo counts, stars, discussion volume, and recency to detect whether the space is accelerating or declining. Useful when your AI agent is about to generate boilerplate for the hundredth React component library and you want it to check the landscape first.

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.
Project status (August 2026): Maintenance mode. The tool works, stays free & open source, and the hosted API remains up; bug reports are reviewed, but no new features are planned.
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.
