Quick Start (30 seconds)

Installation

Option A: Using pip (Recommended)

pip install polarion-mcp

Option B: Using uvx (No local Python needed) Just use directly in mcp.json (see setup below).

Setup

1. Add to your Cursor mcp.json:

{
  "mcpServers": {
    "polarion": {
      "command": "polarion-mcp"
    }
  }
}

2. Restart Cursor

3. In Cursor chat, authenticate:

Open Polarion login
Set Polarion token: <your-token>

Done! 🎉

Configuration

For Claude Desktop (URL-based Server)

If you're connecting to a URL-accessible server (like the GCP demo), Claude Desktop requires a proxy since it doesn't support SSE directly.

Step 1: Install mcp-remote (one-time setup)

npm install -g mcp-remote

Step 2: Configure Claude Desktop

Edit claude_desktop_config.json (location varies by OS):

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

{
  "mcpServers": {
    "polarion-demo": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "http://dev.polarion.atoms.tech:8080/sse"
      ]
    }
  }
}

Step 3: Restart Claude Desktop

The server will connect via the proxy. Then authenticate:

Open Polarion login
Set Polarion token: <your-token>

Connect to Your Polarion Instance

By default connects to http://dev.polarion.atoms.tech/polarion. To use your own instance:

Option 1: Environment Variable

export POLARION_BASE_URL="https://your-polarion.com/polarion"
polarion-mcp

Option 2: In Cursor mcp.json

{
  "mcpServers": {
    "polarion": {
      "command": "polarion-mcp",
      "env": {
        "POLARION_BASE_URL": "https://your-polarion.com/polarion"
      }
    }
  }
}

Option 3: Using uvx with custom URL

{
  "mcpServers": {
    "polarion": {
      "command": "uvx",
      "args": ["polarion-mcp@latest"],
      "env": {
        "POLARION_BASE_URL": "https://your-polarion.com/polarion"
      }
    }
  }
}

• Get Polarion work item: PROJECT_ID ITEM_ID - Get item details

Documents

• Get Polarion document: PROJECT_ID SPACE_ID DOCUMENT_NAME - Access documents

Analysis

• polarion_github_requirements_coverage project_id="PROJECT" topic="HMI" - Requirements coverage

Local Development

Prerequisites

• Python 3.10+
• Access to Polarion instance

Installation

git clone https://github.com/Sdunga1/Polarion-MCP.git
cd Polarion-MCP
pip install -e .

Running

polarion-mcp

Troubleshooting

Can't connect?

• Verify POLARION_BASE_URL is correct
• Check if Polarion instance is accessible
• Verify token hasn't expired

Authentication failed?

• Regenerate token in Polarion
• Use: Open Polarion login → Set Polarion token
• Check: Check Polarion status

Not finding projects?

• Verify user has access to projects in Polarion
• Check authentication: Check Polarion status
