Git Forensics MCP server for AI agents

Git Forensics MCP is a specialized Model Context Protocol server that enables deep git repository investigation and analysis. This forensics tool provides detailed insights into repository history, branch relationships, and development patterns, focusing exclusively on git repository analysis.

Installation Requirements

Before using Git Forensics MCP, ensure you have:

Node.js installed
Git installed and accessible from command line
An MCP-compatible client

Server Features

The server provides four primary analysis tools:

Branch Overview

Provides high-level insight into branch states and relationships:

Last commits analysis
Commit count statistics
Merge base identification
Branch activity summaries

Time Period Analysis

Examines development activity within specific time ranges:

Categorizes commits by type (feature, fix, refactor, docs, other)
Generates activity summaries with commit patterns

File Changes Analysis

Tracks how specific files change across branches:

Identifies potential conflict areas
Assesses risk levels for file modifications
Recommends review priorities based on risk assessment

Merge Recommendations

Helps determine optimal merge strategies:

Conflict risk assessment
Code hotspot identification
Step-by-step merge guidance

Using Git Forensics MCP

Basic Usage

The server functions as an MCP service that can be integrated with any MCP-compatible client. All analysis results are written to specified output files in JSON format.

Required Parameters

For all analysis tools, you'll need to provide:

{
  "repoPath": "/path/to/git/repository",
  "branches": ["main", "feature1", "feature2"],
  "outputPath": "/path/to/output/directory"
}

Tool-Specific Parameters

For Time Period Analysis

{
  "timeRange": {
    "startDate": "2023-01-01",
    "endDate": "2023-03-31"
  }
}

For File Changes Analysis

{
  "files": [
    "src/main.ts",
    "src/utils/helpers.ts",
    "README.md"
  ]
}

Example Usage

To analyze branch relationships:

// MCP client code example
const result = await client.call("get_branch_overview", {
  repoPath: "/path/to/local/repo",
  branches: ["main", "develop", "feature/new-ui"],
  outputPath: "./analysis-results"
});

To analyze file changes:

// MCP client code example
const result = await client.call("analyze_file_changes", {
  repoPath: "/path/to/local/repo",
  branches: ["main", "feature/payment-gateway"],
  files: ["src/payment/processor.ts", "src/models/transaction.ts"],
  outputPath: "./file-analysis"
});

Output Format

All tools generate JSON output files containing:

Detailed analysis results
Summary statistics
Risk assessments (where applicable)
Actionable recommendations

For example, a branch overview output might look like:

{
  "branches": [
    {
      "name": "main",
      "lastCommit": "a1b2c3d4",
      "commitCount": 156,
      "activity": "high"
    },
    {
      "name": "develop",
      "lastCommit": "e5f6g7h8",
      "commitCount": 178,
      "activity": "very high"
    }
  ],
  "relationships": [
    {
      "branches": ["main", "develop"],
      "mergeBase": "i9j0k1l2",
      "divergencePoint": "2023-02-15"
    }
  ]
}

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "git-forensics" '{"command":"npx","args":["-y","git-forensics-mcp"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

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

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json
Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

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

3. Restart Claude Desktop for the changes to take effect
