mcp-server-polarion

Talk to your Polarion — AI reads, writes, and reorganizes documents, work items, test runs, and traceability links.

Features · Quickstart · Tools · Example Prompts · Setup

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.

Features

• 34 tools covering read and write across documents, work items, test runs, 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, 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.

Quickstart

Requires Polarion 2506+ and 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 Client Configuration.

All list tools support pagination via page_size (1–100) and page_number parameters.

Example Prompts

"List the projects I can access, then show the documents in project MCPT with their types."

"List the documents in space 'Specifications' of project MCPT."

"Find every approved requirement in project MCPT whose title starts with 'Auth' and show me their owning document."

"Search project MCPT for work items where the custom field 'verification_method' is 'Test' — grab the SQL recipes first if you need a join."

"Find all work items in the SRS module of project MCPT that were changed in the last sprint."

"Read the SRS document of project MCPT and summarize each open requirement."

"Show me the structural outline of the SRS document — headings and the work items under each."

"Read work item MCPT-042 as Markdown and explain what it asks for."

"Show the outgoing and incoming links for MCPT-042 and flag any child task that is still open."

"Which requirements in the SRS document have no 'verifies' back link from a test case?"

"List the open comment threads on the SRS document and who started each."

"Create a task in project MCPT titled 'Refactor authentication module' and link it to MCPT-042 as 'relates_to'."

"Create three test-case work items in project MCPT from this checklist and link each one to MCPT-042 as 'verifies'."

"Add a new requirement under section 3.2 of the SRS document with the body I just drafted."

"Update the description of MCPT-042 with the revised text I'll paste, keeping the existing formatting."

"Add a comment on the SRS document asking the owner to clarify section 4, then reply to thread T-12 marking it resolved."

"Create a test run REG-SPRINT-7 in project MCPT from the 'Regression' template with status 'open'."

"List the valid status values for a defect in project MCPT, then move MCPT-077 to 'in_review'."

"Bump MCPT-042's priority to 90, set severity to 'major', and approve the workflow."

"Change MCPT-201 from a task to a requirement and re-apply its previous status."

"Move MCPT-201 into the SRS document right after MCPT-150."

"Detach MCPT-077 from its document so I can rework it as a standalone task."

"Mark the 'blocks' link from MCPT-042 to MCPT-099 as suspect, then delete the stale 'relates_to' link to MCPT-010."

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.
