idea_check
Takes a product idea in plain language and reports what already exists in that space — prior art, competitors and market saturation — at the depth you set.
LABSCO SUMMARY
It puts the 'has someone already built this' question where the idea appears, instead of two weeks later.
One tool, one job: you describe the idea while you are still describing it, and five sources answer before the repository exists. The score is less useful than what comes with it — the named projects, their star counts and the trend direction are what turn a hunch into build, pivot or drop.
What it is
A single-tool server. You describe an idea in plain language; it queries GitHub, Hacker News, npm, PyPI and Stack Overflow in parallel and comes back with a score, the projects already occupying that space, and where the interest is heading.
What you get
- A reality signal from 0 to 100, with a duplicate likelihood in words next to it
- A trend reading — accelerating, stable or declining — and a market momentum sub-score, so a crowded space and a growing one are told apart
- The evidence behind the score, source by source: repository and star counts on GitHub, mentions on Hacker News, package counts on npm and PyPI, question counts on Stack Overflow
- The closest existing projects by name, URL, stars and description — the competitor you would have found in week three
- Pivot hints pointing at where the leading project leaves room
- Two depths on the same call: quick reads GitHub and Hacker News, deep goes to all the sources
Requirements
Python with uv, and nothing to configure — no account, no key. GITHUB_TOKEN is worth setting anyway: GitHub's unauthenticated rate limit is what a run of deep checks hits first. The project is in maintenance mode — it works and stays free, but no new features are planned. MIT licensed.
Setup effort
One command — uvx idea-reality-mcp
USE CASES
01
Sanity-checking an idea as you say it out loud
One quick call before any code — GitHub and Hacker News are usually enough to know whether the space is empty.
02
Sizing up the competition properly
Run the deep check, read the closest projects by stars, and see what the pivot hints say the leaders are missing.
03
Telling a crowded market from a dying one
The trend direction and momentum score separate a space with many projects and rising interest from one with many projects and falling interest.
