mcp-server-polarion

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 paced to a rate cap you configure for your instance — so an AI assistant can work on production data without surprises.

Features

• 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 serialized and paced to a configurable rate cap, 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.

Tools

Read

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

Write

Example Prompts

Discovery & search

> "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."

Reading & summarizing

> "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."

Creating & editing

> "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'."

Workflow & reorganization

> "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.
