What diffpilot 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.

What it helps with

review local branch changes before opening a pull request
spot leaked credentials and tokens before creating a commit
generate pull request descriptions with review checklists
get pattern-based test recommendations for altered files

Example prompts for the agent

Review my staged changes with focus on security and error handling
Scan changed files for API keys and tokens before committing
Generate a conventional commit message for the staged changes
