Polarion MCP Server

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.

Features

• 24 tools covering read and write across documents, work items, traceability links, and comments.
• Read — render documents as Markdown, search with Lucene or SQL, walk incoming/outgoing links, resolve enum options.
• Write — create and update work items and documents, manage links, reorganize document structure, post comments.
• Safe writes — every write tool supports dry_run, and pre-write guards validate fields, enum values, and link targets before hitting Polarion.
• Built for LLMs — strict async, fully typed, pagination on every list tool, docstrings written as the assistant's manual.

Quickstart

Requires uv (see Prerequisites). Fastest path — Claude Code:

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

Other clients (VS Code, Claude Desktop, Cursor) — see Setup.

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.
