Git Context MCP server

This is a small helper that answers a question developers ask all the time: why is this line of code here? You point your AI at a file and a line, and it digs through your project's history to find the story behind it. It is handy for anyone who has ever stared at old code and wondered who wrote it and why.

What this MCP server does

You ask your AI something like why a certain line of code exists. The AI passes that request to this helper. The helper looks at your project's saved history to find which change added that line, then checks GitHub for the pull request that brought it in and any issues linked to it. It gathers all of that into a tidy answer and hands it back to your AI, which shows it to you in the chat. You get the commit, the person, the date, the pull request description and the linked issues, all in one place.

• “What's the story behind commit d4a8f91?”
• “Who owns the most of src/payments/stripe.ts?”
• “Show me the last 5 changes to src/api/auth.ts and why each was made”

What it gives back to you

You get a written answer in the chat. It usually includes the commit message, who made it and when, the pull request title and description, and any linked issues with their status. For contributor questions you get a ranked list of names with how many commits and lines they own.
