1 | # Git Forensics MCP
2 |
3 | A specialized Model Context Protocol (MCP) server for deep git repository investigation and analysis. This forensics tool provides detailed insights into repository history, branch relationships, and development patterns, focusing solely on git repository analysis rather than general GitHub or git operations.
4 |
5 | ## Features
6 |
7 | The server provides four main analysis tools:
8 |
9 | 1. **Branch Overview** (`get_branch_overview`)
10 | - Provides high-level overview of branch states and relationships
11 | - Analyzes last commits, commit counts, and merge bases
12 | - Generates statistical summaries of branch activities
13 |
14 | 2. **Time Period Analysis** (`analyze_time_period`)
15 | - Analyzes detailed development activity in specific time periods
16 | - Categorizes commits (feature, fix, refactor, docs, other)
17 | - Provides activity summaries with commit patterns
18 |
19 | 3. **File Changes Analysis** (`analyze_file_changes`)
20 | - Tracks changes to specific files across branches
21 | - Identifies potential conflict areas
22 | - Provides risk assessment for file modifications
23 | - Generates recommended review order based on risk levels
24 |
25 | 4. **Merge Recommendations** (`get_merge_recommendations`)
26 | - Determines optimal merge strategies
27 | - Assesses conflict risks
28 | - Identifies code hotspots
29 | - Provides step-by-step merge guidance
30 |
31 | ## Input Parameters
32 |
33 | Each tool requires specific parameters:
34 |
35 | - `repoPath`: Path to the git repository
36 | - `branches`: Array of branch names to analyze
37 | - `outputPath`: Path where analysis results will be written
38 | - Additional tool-specific parameters:
39 | - `timeRange`: Start and end dates for period analysis
40 | - `files`: Array of file paths for file change analysis
41 |
42 | ## Output Format
43 |
44 | All tools output JSON files containing:
45 | - Detailed analysis results
46 | - Summary statistics
47 | - Risk assessments (where applicable)
48 | - Recommendations based on analysis
49 |
50 | ## Technical Details
51 |
52 | - Built with TypeScript
53 | - Uses MCP SDK for server implementation
54 | - Executes git commands through child processes
55 | - Provides error handling and validation
56 | - Runs on stdio transport
57 |
58 | ## Dependencies
59 |
60 | - @modelcontextprotocol/sdk
61 | - Node.js
62 | - Git (must be installed and accessible)
63 |
64 | ## Usage
65 |
66 | The server runs as an MCP service and can be integrated with any MCP-compatible client. All analysis results are written to specified output files in JSON format.

157 | negligent acts) or agreed to in writing, shall any Contributor be
158 | liable to You for damages, including any direct, indirect, special,
159 | incidental, or consequential damages of any character arising as a
160 | result of this License or out of the use or inability to use the
161 | Work (including but not limited to damages for loss of goodwill,
162 | work stoppage, computer failure or malfunction, or any and all
163 | other commercial damages or losses), even if such Contributor
164 | has been advised of the possibility of such damages.
165 |
166 | 9. Accepting Warranty or Additional Liability. While redistributing
167 | the Work or Derivative Works thereof, You may choose to offer,
168 | and charge a fee for, acceptance of support, warranty, indemnity,
169 | or other liability obligations and/or rights consistent with this
170 | License. However, in accepting such obligations, You may act only
171 | on Your own behalf and on Your sole responsibility, not on behalf
172 | of any other Contributor, and only if You agree to indemnify,
173 | defend, and hold each Contributor harmless for any liability
174 | incurred by, or claims asserted against, such Contributor by reason
175 | of your accepting any such warranty or additional liability.
