Polarion MCP Server

getTestRecordAttachments

Read-only

Returns attachments for a Polarion test record by providing project, test run, test case IDs, and iteration. Supports paging and selective fields to reduce payload.

Instructions

Returns a list of Test Record Attachments. Cardinality: targets the full collection or a batch. For a single item by ID, use getTestRecordAttachment instead.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
fieldsNoSparse fieldset selector: an object keyed by resource type (e.g. `workitems`) whose value is a comma-separated list of attribute names to return (e.g. `id,title,status`), reducing payload size. Omit to return the default field set.
includeNoComma-separated list of related resource types to embed in the response (e.g. `author,attachments`) so they don't require a separate follow-up call. Omit to return only the primary resource.
revisionNoA specific repository revision (e.g. `1234`) to read the resource as it existed at that revision instead of the current HEAD. Omit to use the latest revision.
iterationYesThe iteration number identifying which repeated occurrence of this item is being addressed (e.g. which run of a test parameter).
projectIdYesThe 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.
testRunIdYesThe Test Run's ID within its project.
page_size_NoMaximum number of items to return in this page (e.g. `100`). Use together with `page[number]` to paginate through a large result set.
testCaseIdYesThe Test Case's ID being referenced.
page_number_No1-based page number to fetch when the result set is paginated (e.g. `2` for the second page). Combine with `page[size]`; omit to fetch the first page.
testCaseProjectIdYesThe project ID that owns the referenced Test Case — may differ from the project in the request path when the test case is shared from another project.

A4/5.0
Behavior3/5

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

The readOnlyHint and openWorldHint annotations already cover the safety profile. The description adds a useful cardinality clarification ('full collection or a batch') but does not disclose additional behavioral details such as whether this returns only metadata or where to fetch actual attachment content.

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 two sentences with no filler. The primary action and cardinality are front-loaded, and the singular-endpoint alternative is stated efficiently.

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

Completeness4/5

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

The schema fully documents the complex required parameters, and an output schema exists, so return-value details are covered. The main gap is that the description does not explicitly say whether this returns only metadata or point to getTestRecordAttachmentContent for content, but this is a minor omission for a collection-list tool.

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?

All 10 parameters are already described in the input schema with 100% coverage, so the description does not need to repeat them. The description adds no extra parameter-level meaning, which is acceptable given the strong schema documentation.

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?

The description states a specific verb and resource ('Returns a list of Test Record Attachments') and explicitly distinguishes this collection endpoint from the singular getTestRecordAttachment. The cardinality note reinforces that this is not a single-item fetch.

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

Usage Guidelines4/5

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

It clearly says to use getTestRecordAttachment for a single item by ID, giving a concrete when-not-to-use rule. It does not mention other related attachment endpoints (e.g., test run or work item attachments), but the resource name and sibling context make the intended scope reasonably clear.

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