Polarion MCP Server

branchDocuments

Create a branched copy of a Polarion document in a specified project and space, with options to set target name/title, overwrite work items, and copy workflow status.

Instructions

Creates Branches of Documents. 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.

TDQS

A4.1/5.0

Behavior5/5

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

The description goes well beyond the annotations. It explicitly warns that the operation is not guaranteed idempotent, that repeating it may be safe, a no-op, or rejected depending on the action, and explains the dry_run preview behavior including the error-flagged result quirk. This is rich behavioral context that annotations alone (readOnlyHint=false, idempotentHint=false) do not provide.

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

Conciseness4/5

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

The description is compact and front-loaded with the core purpose, then adds the critical idempotency warning and dry-run tip. Every sentence earns its place. It loses one point because the dry_run explanation is somewhat dense and could be split for readability, but it's still efficient.

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?

Given the tool's complexity (nested requestBody, 10 sub-parameters, no idempotency guarantee), the description covers the most critical operational concerns: the server-side action nature, idempotency risk, and the dry_run safety mechanism. The output schema exists, so return values don't need explanation. It doesn't mention prerequisites like permissions, but the dry-run guidance partially compensates.

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 schema already documents all parameters thoroughly. The description adds value by explaining the dry_run parameter's behavior in detail, but it doesn't add meaning to the requestBody fields beyond what the schema provides. Baseline 3 is appropriate.

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

Purpose4/5

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 Branches of Documents') and distinguishes it from plain resource creation by noting it triggers a server-side action. It doesn't explicitly name sibling tools like branchDocument or copyDocument, but the phrase 'Branches of Documents' plus the server-side action warning makes the core purpose clear.

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 for when to use the tool (when branching documents) and provides a strong practical guideline: set dry_run: true first to preview the request. It doesn't explicitly say when not to use it or name alternatives, but the dry-run tip effectively guides safe usage.

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