## What it does

DiffPilot runs static checks and code reviews over your local Git workspace before you open a pull request. It resolves the base branch automatically, picking `main`, `master`, or `develop`. All scans happen on the local machine. This design keeps proprietary code safe inside air-gapped environments or private Azure DevOps repositories.

The server exposes 9 tools through MCP. These tools compose pull request summaries, suggest test cases, calculate line statistics, and draft Conventional Commits. A built-in scanner redacts passwords, JWTs, AWS credentials, and API keys before they reach the review output. It also caps traffic at 120 requests per minute to prevent overload.

Running DiffPilot requires Git and the .NET 9 SDK. Without .NET 9 present on your machine, the binary cannot start.
