There are MCP Servers that give access to git repo information to any LLM supporting MCP Servers.

For example:

>The GitHub MCP Server connects AI tools directly to GitHub's platform. This gives AI agents, assistants, and chatbots the ability to read repositories and code files, manage issues and PRs, analyze code, and automate workflows. All through natural language interactions.
