mcp-server-polarion

A Model Context Protocol (MCP) server for Polarion ALM. Lets AI assistants read documents, work items, and traceability links — and create, update, and reorganize work items — directly from your Polarion instance.

Prerequisites

Polarion 2506 or higher is required. Earlier versions lack REST API endpoints this server depends on.

This server is distributed as a Python package and requires uv to run.

Install uv (if not already installed):

# macOS / Linux
curl -LsSf https://astral.sh/uv/install.sh | sh

# Windows
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

Or via pip:

pip install uv

No other installation is needed — uvx mcp-server-polarion downloads and runs the server automatically.

Setup

Environment Variables

MCP client env objects must use string values, so booleans are quoted (e.g. "POLARION_VERIFY_SSL": "true"). The server parses "true" / "false" into a real bool.

Add to .vscode/mcp.json:

{
  "servers": {
    "mcp-server-polarion": {
      "type": "stdio",
      "command": "uvx",
      "args": ["mcp-server-polarion"],
      "env": {
        "POLARION_URL": "https://polarion.example.com",
        "POLARION_TOKEN": "your-personal-access-token",
        "POLARION_VERIFY_SSL": "true"
      }
    }
  }
}

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "mcp-server-polarion": {
      "command": "uvx",
      "args": ["mcp-server-polarion"],
      "env": {
        "POLARION_URL": "https://polarion.example.com",
        "POLARION_TOKEN": "your-personal-access-token",
        "POLARION_VERIFY_SSL": "true"
      }
    }
  }
}

Add to Cursor MCP settings:

{
  "mcpServers": {
    "mcp-server-polarion": {
      "command": "uvx",
      "args": ["mcp-server-polarion"],
      "env": {
        "POLARION_URL": "https://polarion.example.com",
        "POLARION_TOKEN": "your-personal-access-token",
        "POLARION_VERIFY_SSL": "true"
      }
    }
  }
}

Register via the claude mcp add command:

claude mcp add mcp-server-polarion \
  -e POLARION_URL=https://polarion.example.com \
  -e POLARION_TOKEN=your-personal-access-token \
  -e POLARION_VERIFY_SSL=true \
  -- uvx mcp-server-polarion
