MCP Server

If you already use MCP, the mcp mcp server is the piece that lets your assistant work with it directly. MCP server for Polarion ALM — read and write documents and work items.

What the server does

A Model Context Protocol (MCP) server for Polarion ALM, built for real-world instances: every write supports dry_run, guards validate fields and enum values before anything is committed, and requests are automatically paced to Polarion's rate limits — so an AI assistant can work on production data without surprises.

• 46 tools — covering read and write across documents, work items, test runs, traceability links, comments, and attachments
• Read — — render documents as Markdown, search with Lucene or SQL, walk incoming/outgoing links, resolve enum options
• Write — — create and update work items, documents, and test runs, 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
• Plays nice with your server — — requests are paced to Polarion's rate limits, with automatic retries on 429/5xx responses
• Built for LLMs — — strict async, fully typed, pagination on every list tool, docstrings written as the assistant's manual

Installation

The server ships on PyPI as mcp-server-polarion, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

• Read — All list tools support pagination via page_size (1–100) and page_number parameters
• Write — The Write tool exposed by this server
• Prerequisites — This server is distributed as a Python package and requires uv to run

Credentials and setup notes

Configuration is passed through the environment: POLARION_URL, POLARION_TOKEN. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

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): ```bash

Worth knowing first

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
• Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Where it fits

This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. MCP's toolset — Read, Write, Prerequisites — is a fair guide to whether it matches your workflow. It is maintained by devemberx; worth a glance at recent repository activity before you build anything load-bearing on it.
