Git Summary MCP server

git-summary-mcp

An MCP server that gives AI assistants deep understanding of your local Git repositories. Get instant repo overviews, semantic change summaries, blame analysis, auto-generated changelogs, branch health checks, and history search — all from within Claude, Cursor, or any MCP client.

Quick Start

npx git-summary-mcp

Zero config. No API keys. No accounts. Just run it in any Git repository.

Tools

git_summary

Structured overview of a repository: current branch, recent commits, contributors, and stats.

"Summarize this repository"
"Who are the top contributors?"
"Show me the last 10 commits"

git_changes

Semantic change summary for any commit range. See what files changed, who changed them, and the overall diff stat.

"What changed between v1.0 and v2.0?"
"Summarize the changes in the last week"
"What did the feature branch change?"

git_blame

Analyze file ownership: who wrote each line, when, and in which commit. Get contributor breakdowns.

"Who last modified src/index.ts?"
"Show me the blame for lines 50-100 of app.py"
"Who owns most of this file?"

git_changelog

Auto-generate a changelog grouped by commit type (features, fixes, docs, etc.) using conventional commit detection.

"Generate a changelog for the last release"
"Create release notes from v1.0 to v2.0"

gitbranchhealth

Find stale branches, merged branches ready for cleanup, and branches that are ahead/behind.

"Which branches are stale?"
"Any branches that have been merged and can be deleted?"
"Show me branch health"

git_search

Search through commit messages and code changes (pickaxe search) to find when something was introduced or changed.

"When was the login function added?"
"Find commits that mention 'authentication'"
"When was this config value changed?"

Installation

Claude Desktop / Claude Code

Add to your MCP config:

{
  "mcpServers": {
    "git-summary": {
      "command": "npx",
      "args": ["-y", "git-summary-mcp"]
    }
  }
}

Cursor

Add to .cursor/mcp.json:

{
  "mcpServers": {
    "git-summary": {
      "command": "npx",
      "args": ["-y", "git-summary-mcp"]
    }
  }
}

Windsurf

Add to your MCP configuration with the same format as above.

Why?

AI coding assistants can read files and run commands, but they don't inherently understand your project's history. This MCP server gives them structured, token-efficient Git intelligence so they can:

• Understand who worked on what and when
• Generate accurate changelogs and release notes
• Find when bugs were introduced
• Identify stale branches and cleanup opportunities
• Summarize changes for code reviews and PRs

Requirements

• Node.js 18+
• Git installed and available in PATH
• Must be run inside (or pointed at) a Git repository
