Veeam VBR v13 MCP Server

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions retrieving data but does not specify if this is a read-only operation, requires permissions, involves pagination, or has rate limits. For a tool with three parameters and no annotation coverage, this leaves significant gaps in understanding its behavior and constraints.

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

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

The description is a single, clear sentence that directly states the tool's purpose without unnecessary words. It is front-loaded and efficient, making it easy to parse quickly, which is ideal for conciseness in tool definitions.

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

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

Given the tool's complexity (3 parameters, no annotations, no output schema), the description is inadequate. It does not explain the return format, error conditions, or how parameters affect results. For a list/retrieval tool with filtering capabilities, more context is needed to guide proper usage and expectations.

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

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

The input schema has three parameters (skip, limit, nameFilter) with 0% description coverage, meaning the schema provides no semantic details. The tool description does not mention or explain any parameters, failing to compensate for the low schema coverage. This leaves the agent without guidance on what these parameters do or how to use them effectively.

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

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

The description clearly states the verb ('Get') and resource ('all users and groups with access to Veeam Backup & Replication'), making the purpose specific and understandable. However, it does not explicitly distinguish this tool from sibling tools like 'GetUser', 'GetAllUsers', or 'ViewUsersSettings', which might have overlapping or related functionality, preventing a perfect score.

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

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

The description provides no guidance on when to use this tool versus alternatives, such as filtering options (e.g., 'GetUser' for a specific user) or related tools in the sibling list. It lacks context on prerequisites, exclusions, or typical scenarios for invocation, leaving the agent with minimal usage direction.

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