🐍 Gerrit MCP Server

An MCP (Model Context Protocol) server for interacting with the Gerrit code review system. This server allows a language model like Gemini to query changes, retrieve details, and manage reviews by executing curl commands against the Gerrit REST API.

This server can be run as a persistent HTTP server or on-demand via STDIO.

🚀 Getting Started

1. Prerequisites

Before you begin, ensure you have the following tools installed and available in your system's PATH.

• Python 3.12+: Required by the server.
• uv: Used for dependency management and running the server. Optional — the build script will install it via pip if absent.
• curl: The standard command-line tool for transferring data with URLs.

2. Build the Environment

Run the build script from the root of the gerrit-mcp-server project directory. This will create a virtual environment in .venv via uv sync and install all dependencies.

./build-gerrit.sh

3. Configure the Server

You will need to create a gerrit_config.json file inside the gerrit_mcp_server directory. Copy the provided sample file gerrit_mcp_server/gerrit_config.sample.json and customize it for your environment. See the Configuration Guide for details on all available options.

cp gerrit_mcp_server/gerrit_config.sample.json gerrit_mcp_server/gerrit_config.json

4. Run the Server (HTTP Mode)

To run the server as a persistent background process, use the server.sh script:

• Start the server:

  ./server.sh start

• Check the status:

  ./server.sh status

• Stop the server:

  ./server.sh stop

For on-demand STDIO mode, please see the Gemini CLI Setup Guide.
