Describe the pull request
Enter PR size, critical-path overlap, existing test coverage of the changed area, reviewers who have already approved, and how much of it is AI-generated.

How it works
We calculate a weighted gate score
Size and critical-path overlap set the base requirement, weak coverage and heavy AI generation raise it, and existing reviewer approvals reduce it — a transparent 0-100 gate score.
Get a clear merge-gate recommendation
The score maps to one of three actions: auto-mergeable, needs one more reviewer, or needs senior review, plus the specific factors driving that call.

Frequently asked questions
Does this scan my actual pull request?
No. This tool computes a merge-gate recommendation entirely from the PR characteristics you enter — size, critical-path overlap, test coverage, reviewer count, and AI-generation level. It does not parse real pull requests, diffs, or commits, and does not connect to any version control or CI system.
How is this different from AICommit Review?
AICommit Review scores the risk of one commit that has already been made, flagging categories that need manual review. Merge Guard AI evaluates a whole pull request as a unit and outputs a policy recommendation for the merge decision itself — auto-mergeable, needs one reviewer, or needs senior review. Use AICommit Review to triage individual commits and Merge Guard AI to decide the review bar for the PR as a whole.
Why does reviewer count reduce the gate score?
A PR that already has one or more approvals has had some of the risk addressed by human review, so the additional gate required is lower than an identical, unreviewed PR — but the score can still land at "needs senior review" if critical-path overlap or coverage is weak enough.
Can I use this to fully automate merge decisions?
No — this is a recommendation based on the factors you enter, not an enforced gate. Wire the recommendation into your own branch protection rules or review policy if you want it enforced.
What does "critical-path overlap" mean?
Whether the PR touches code shared broadly across the app (heavy: auth, payments, core data flow) versus an isolated feature (none). Heavy overlap raises the gate score substantially because a mistake there affects more of the product.
How We Compare
| Feature | MVPHub | GitHub Copilot | Cursor |
|---|---|---|---|
| Weighted merge-gate recommendation for a PR | Included | Not included | Not included |

GitHub Copilot and Cursor can generate the PR's code and offer inline review suggestions, but neither computes a standalone merge-gate policy recommendation from PR-level risk factors. Merge Guard AI gives a fast, structured read on how much review a given PR should require before it merges.
