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 full burden. 'Browse' implies a read-only operation, but it doesn't disclose whether this requires specific permissions, what format the contents are returned in, whether it's paginated, or any rate limits. For a tool with no annotation coverage, this leaves significant behavioral gaps.

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, efficient sentence that directly states the tool's purpose. It's appropriately sized for what it does convey, with no wasted words or unnecessary elaboration. The structure is front-loaded with the core functionality.

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 (2 parameters with nested objects, 0% schema coverage, no annotations, no output schema), the description is inadequate. It doesn't explain what 'browsing' returns, how to interpret results, or provide any parameter context. For a tool that presumably returns structured data about vault contents, this leaves too many unanswered questions.

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?

Schema description coverage is 0%, so the description must compensate. It mentions no parameters at all - not explaining what 'vaultId' represents, what the 'body' object is for, or their required formats. With 2 parameters (one required) and no schema descriptions, this leaves the agent guessing about proper usage.

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 'Browse the contents of a Veeam Data Cloud Vault' clearly states the action (browse) and target resource (Veeam Data Cloud Vault contents). However, it doesn't distinguish this tool from similar siblings like 'BrowseCloudEntity' or 'BrowseCloudEntityVirtualMachines' - the specific scope or differences aren't explained, making it vague in comparison.

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?

No guidance is provided about when to use this tool versus alternatives. With numerous sibling tools including other browsing operations, the description offers no context about prerequisites, appropriate scenarios, or exclusions. The agent must infer usage from the name alone.

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