Polarion MCP Server

postLinkedWorkItems

Creates direct outgoing links from a Polarion Work Item to other Work Items. Use dry_run to preview the request before sending; each call creates a new link, so repeated calls produce duplicates.

Instructions

Creates the direct outgoing links to other Work Items. (The same as the corresponding Java API method.) Does not pertain to external links or backlinks. Effect: creates a new resource on each call — calling it again with the same input creates a duplicate; it is not 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
`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.
`workItemId`	Yes	The Work Item's ID within its project (e.g. `WI-123`), not the combined `project/id` path used in some link payloads.
`requestBody`	Yes	The Linked Work Item(s) body.

A4.5/5.0

Behavior5/5

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

The description discloses important non-idempotent behavior: calling it again with the same input creates a duplicate. It also explains the dry_run preview behavior, including the nuance that the preview is error-flagged because it is not real tool output. This goes well beyond the annotations, which only declare idempotentHint=false.

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 compact and front-loaded: purpose first, exclusions second, behavioral effect third, and a practical dry_run tip last. Every sentence contributes necessary operational information, and the wording is direct without excessive detail.

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?

For a mutation tool with a nested body and an output schema, the description covers the essential context: the link type scope, duplicate-creation behavior, non-idempotency warning, and dry_run workflow. Since an output schema exists, the description does not need to explain return values, and nothing critical is missing.

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 description coverage is 100%, so the input schema already documents all parameters thoroughly. The description adds useful context about the requestBody's meaning (direct outgoing work item links) and the dry_run tip, but it does not add substantially new per-parameter semantics beyond what the schema already provides.

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: "Creates the direct outgoing links to other Work Items." It explicitly distinguishes itself from external and backlink operations, which clearly separates it from sibling tools like getBacklinkedWorkItems, postBacklinkedWorkItems, and postExternallyLinkedWorkItems.

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?

The description gives clear context by specifying this tool handles direct outgoing links and "does not pertain to external links or backlinks." It does not name alternative tools explicitly, but the exclusion is unambiguous enough to steer an agent toward the right sibling for other link types.

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