Veeam VBR v13 MCP Server

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the action but doesn't reveal if this is a read-only or mutating operation, its side effects (e.g., triggers updates, requires permissions), or any rate limits. This is inadequate for a tool that likely involves system changes.

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 with no unnecessary words, making it highly concise and front-loaded. It efficiently communicates the core action without redundancy.

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 complexity (likely a mutating operation with no annotations or output schema) and poor schema coverage, the description is incomplete. It doesn't explain the tool's behavior, output, or parameter details, making it insufficient for safe and effective use.

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 1 parameter with 0% description coverage, and the tool description adds no information about the 'id' parameter (e.g., what it refers to, format, or examples). This fails to compensate for the schema's lack of documentation, leaving the parameter's meaning ambiguous.

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 states the action ('Rescan') and target ('a specific managed server'), which clarifies the basic purpose. However, it doesn't specify what 'rescan' entails (e.g., refreshing inventory, updating status) or differentiate it from similar tools like 'RescanAllManagedServers' or 'RescanInventoryObjects', making it somewhat vague.

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 'RescanAllManagedServers' for bulk operations or 'RescanInventoryObjects' for different scopes. There's no mention of prerequisites, timing, or exclusions, leaving usage unclear.

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