mcp-git-chronicle

License: MIT

A zero-dependency Model Context Protocol (MCP) server providing deep Git archaeology, churn hotspot detection, and co-change coupling analysis to AI coding agents (OpenCode, Cursor, Claude Code).

Why mcp-git-chronicle?

AI coding agents make bad assumptions when editing code without knowing the repository's history:

  1. Volatile Code: They modify fragile files that historically cause high bug rates.

  2. Hidden Coupling: They edit a function or schema in File A, completely unaware that File B and File C always need matching changes.

  3. Missing Context: They fail to understand why a particular architecture decision was made 3 months ago.

mcp-git-chronicle connects your agents directly to local Git plumbing via standard MCP tools over stdio.

Tools Exposed

Tool Name

Parameters

Description

git_churn_hotspots

cwd, since, limit

Identifies top files with highest churn (additions + deletions) and commit volume.

git_co_changes

file, cwd, limit

Calculates semantic file coupling (which files historically commit together with target).

git_recent_context

cwd, count, path

Summarizes recent commit subjects, hashes, and authors to anchor agent awareness.

Setup with Coding Agents

OpenCode / Cursor (~/.config/opencode/config.json or .cursor/mcp.json)

    "git-chronicle": {
      "command": "npx",

    Enables AI coding agents to retrieve cited git-history explanations for files and tickets, compile a Team Engineering Contract from repository artifacts, and follow guided Understand/Build workflows over MCP stdio. It lets clients such as Grok, Claude Code, Codex, Kiro, and Cursor share the same tools for evidence-backed repository understanding.
