mcp-server-git: A Model Context Protocol Server for Git Repository Interaction and Automation

Overview: What is mcp-server-git MCP Server?

mcp-server-git is an advanced Model Context Protocol (MCP) server designed to facilitate interaction with Git repositories through Large Language Models (LLMs). This server integrates seamlessly with various AI applications, enabling them to perform critical tasks like reading, searching, and manipulating Git repositories. Currently in early development, mcp-server-git supports a suite of tools that allow for comprehensive management of Git workflows.

The MCP protocol serves as a standardized interface between AI applications and data sources, ensuring compatibility across different systems and facilitating easy integration. With mcp-server-git, developers can leverage the power of LLMs to automate mundane tasks such as committing changes, creating branches, or fetching logs from repositories, thus enhancing productivity in software development workflows.

🔧 Core Features & MCP Capabilities

mcp-server-git is a robust tool that leverages Model Context Protocol (MCP) to offer a wide range of Git operations. Each tool provided by the server adheres strictly to the MCP protocol, enabling seamless integration with various AI applications and clients. Here are the key features and their corresponding MCP capabilities:

1. git_status(): Shows the working tree status of a Git repository.

   • MCP Protocol Implementation Details: This function sends a request via the MCP protocol to retrieve the current status of the working directory, which is then returned as text output.

2. git_diff_unstaged(): Displays changes in the working directory that have not yet been staged for commit.

   • MCP Protocol Implementation Details: The server sends an MCP message requesting the unstaged changes, and returns the diff output to the client.

3. git_diff_staged(): Shows changes that are staged for commit.

   • MCP Protocol Implementation Details: Similar to git_diff_unstaged(), but focuses on tracked files in the staging area.

4. git_diff(target): Compares the current state of the repository with a target branch or commit.

   • MCP Protocol Implementation Details: Sends an MCP request to compare the specified branches/commits and returns the diff output to the client.

5. git_commit(message): Records changes to the repository.

   • MCP Protocol Implementation Details: Submits a commit message via the MCP protocol, effectively committing changes to the Git repository with a confirmation of the new commit hash returned by the server.

6. git_add(files): Stages file contents for commit.

   • MCP Protocol Implementation Details: Sends an MCP request with the list of files to stage, and returns a confirmation of the staged actions performed on those files.

7. git_reset(): Unstages all changes in the repository.

   • MCP Protocol Implementation Details: Resets the Git index back to its previous state before any staging occurred, providing an MCP response confirming the completion of this action.

8. git_log([max_count: 10]): Shows the commit logs with options for customizing the number of commits displayed.

   • MCP Protocol Implementation Details: Sends an MCP request to retrieve a specified number of recent commits (with defaults), then returns an array of commit entries containing information such as hash, author, date, and message.

9. git_create_branch(name[, start_point]): Creates a new branch based on the current state or a specific starting point.

   • MCP Protocol Implementation Details: Sends an MCP request to create a new branch with optional parameters for specifying the initial commit as a reference.

10. git_checkout(branch_name): Switches branches within the repository.

    • MCP Protocol Implementation Details: Sends an MCP request to change the checkout branch, returning a confirmation upon successful switch.

⚙️ MCP Architecture & Protocol Implementation

mcp-server-git operates under the Model Context Protocol (MCP), which standardizes the interaction between AI applications and their underlying data sources. The protocol ensures that operations performed through this server are consistent and predictable across different systems and tools.

🚀 Getting Started with Installation

To get started with using mcp-server-git, you can choose between a development or production setup.

Using uv (Recommended)

For those familiar with the Astral project's tools:

1. Ensure uv and uvx are installed by following the documentation from Astral.
2. Run your command through uvx, which executes mcp-server-git.

Using PIP

If you prefer a standard Python environment, install mcp-server-git using pip:

pip install mcp-server-git

Run the server with:

python -m mcp_server_git

💡 Key Use Cases in AI Workflows

1. Commit Automation: LLMs can automatically commit code changes, reducing manual intervention and increasing deployment speed.

   Example Scenario:
   - A developer working on a feature branch suddenly receives feedback to make urgent modifications.
   - Instead of manually committing the new change back into their branch, an LLM can quickly review the proposed modification and automatically stage then commit it with concise reasons via MCP commands.
   

2. Repository Management: Developers face frequent branching and merging tasks; these processes can be streamlined using automated flow management provided by LLMs.

   Example Scenario:
   - When multiple developers are simultaneously working on different features of the same application, there might be constant conflicts.
   - Using an AI-driven branch creation tool via MCP commands, a developer could quickly identify and create a new feature branch from a base commit with minimal effort.
