Wikimedia Phabricator MCP server

This MCP server provides a standardized interface for LLMs to interact with Phabricator API, allowing tasks management, project information retrieval, and access to user details through a Model Context Protocol implementation.

Prerequisites

Before installing the Phabricator MCP server, ensure you have:

• Python 3.8 or newer
• A valid Phabricator API token
• Access to a Phabricator instance

Installation

Step 1: Clone the Repository

git clone https://github.com/baba786/phabricator-mcp-server.git
cd phabricator-mcp-server

Step 2: Set Up a Virtual Environment

python -m venv venv

# On Unix/MacOS
source venv/bin/activate

# On Windows
.\venv\Scripts\activate

Step 3: Install Dependencies

pip install -r requirements.txt

Step 4: Configure Environment Variables

# Copy the example environment file
cp .env.example .env

# Edit the .env file and add your Phabricator API token
echo "PHABRICATOR_TOKEN=your-token-here" > .env

Make sure to replace your-token-here with your actual Phabricator API token.

Step 5: Start the Server

cd src
python server.py

Usage

The MCP server currently supports the following operations:

Get Task Details

You can retrieve information about a specific Phabricator task using the get-task command.

Here's how to use it with the client:

from src.mcp_minimal_client import Client

# Initialize the client
client = Client()

# Get task details (replace 123 with an actual task ID)
task_response = client.get_task(task_id="123")

# Print the response
print(task_response)

Available Commands

• get-task: Retrieves detailed information about a specific Phabricator task

Connection Details

By default, the server runs locally. When using the client, ensure you're connected to the correct server instance.

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 "phabricator-mcp-server" '{"command":"python","args":["src/server.py"],"cwd":"${workspaceFolder}"}'

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": {
        "phabricator-mcp-server": {
            "command": "python",
            "args": [
                "src/server.py"
            ],
            "cwd": "${workspaceFolder}"
        }
    }
}

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": {
        "phabricator-mcp-server": {
            "command": "python",
            "args": [
                "src/server.py"
            ],
            "cwd": "${workspaceFolder}"
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
