Polarion MCP Server

unmarkProject

Remove a Polarion project's marker to retire it while preserving its data, enabling later re-registration.

Instructions

Removes the Polarion project marker from a project so it no longer appears or works as a project, while its data stays in the repository and can be re-registered later with markProject. Runs as an asynchronous job and returns a jobs resource; poll getJob until it finishes. Use it to retire a project reversibly; to delete the project and its data use deleteProject. Effect: triggers a server-side action rather than a plain resource creation — whether repeating it is safe, a no-op, or rejected depends on the specific action; treat it as not guaranteed idempotent. Tip: set dry_run: true first to preview the exact request Polarion would receive, without changing anything. On tools with a typed output schema, this preview is returned as an error-flagged result since it is not real tool output -- read the text content regardless of that flag.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`dry_run`	No	If true, validates the request and returns the exact request that would be sent to Polarion — with the Authorization header redacted and any binary payload summarized by byte length — without actually sending it.
`projectId`	Yes	The Polarion project ID (its URL segment, e.g. `myproject`), case-sensitive. Required to scope the request to one project; call getProjects to list valid IDs.

A4.7/5.0

Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare non-idempotent and non-destructive, but the description adds crucial detail: it triggers a server-side action, idempotency is not guaranteed, and it returns a jobs resource requiring polling. Also explains dry_run preview behavior and error-flagging. No contradiction with annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is dense but every sentence earns its place: main effect, async behavior, usage comparison, idempotency warning, and dry_run tip. Front-loaded with the core action, well-structured, and not redundant.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (async, non-idempotent, reversible), the description is comprehensive. It covers what it does, how to use it, what to expect (jobs resource), how to verify completion, and contrasts with siblings. The output schema exists, so return format is covered elsewhere. Nothing missing for correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema descriptions for both parameters are highly detailed (dry_run explains exact request preview, projectId explains case-sensitivity and scoping). The description adds a usage tip for dry_run but does not add meaning beyond schema; baseline for 100% coverage is 3.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (Removes), resource (Polarion project marker), and explains the effect on the project (no longer appears/works as a project) while data stays. Clearly distinguishes from markProject (re-registration) and deleteProject (deletes data).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly provides when to use (retire a project reversibly), when not (use deleteProject to delete data), and mentions the async job with polling via getJob. Also recommends dry_run for preview, giving clear operational guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
