Parallels RAS MCP Server

Published VDI Apps

ras_pub_get_vdi_apps
Read-onlyIdempotent

Retrieve published VDI applications to review which apps run on dedicated virtual machines, and compare them with RDS app assignments.

Instructions

List published VDI applications. VDI apps run on dedicated virtual machines rather than shared RDS hosts. Use this to review VDI-published applications or compare with RDS app assignments.

Input Schema

NameRequiredDescriptionDefault
limitNoMax rows after filtering. Default 50, max 200. Prefer narrowing with `filter` over raising the limit.
fieldsNoTop-level keys to keep on each row. Unknown keys are dropped. Use this to shrink large responses to only the columns you need.
filterNoEquality filter on top-level fields (AND across keys). String values match case-insensitively.

TDQS

A3.6/5.0
Behavior3/5

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

The annotations already declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint=false, so the safety profile is fully covered structurally. The description only adds domain context (dedicated VM hosting), and says nothing about result size, filtering cost, or pagination behavior beyond what the schema states.

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?

Two tight sentences, zero filler, with the core purpose front-loaded before the differentiating domain detail. Every clause earns its place.

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?

For a read-only list tool with fully documented parameters and rich annotations, the description supplies adequate context to call it correctly. The one gap is explicit routing to the RDS/AVD siblings, which would be relevant given the densely populated ras_pub_* family.

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 limit, fields, and filter are already well documented in the schema. The description contributes no additional parameter meaning, which is the expected baseline when the schema does the heavy lifting.

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 ('List published VDI applications') and adds a domain distinction ('run on dedicated virtual machines rather than shared RDS hosts') that separates it from the RDS/AVD siblings. It does not name the sibling tool directly, but the VDI-vs-RDS framing is enough for an agent to disambiguate.

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

Usage Guidelines3/5

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

'Use this to review VDI-published applications or compare with RDS app assignments' gives an implied context and alludes to the alternative (RDS apps), but never explicitly names ras_pub_get_rds_apps or states when NOT to use this. Usage is inferable rather than explicit.

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