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 full burden but offers minimal behavioral insight. 'Start finalizing/migrating' implies a potentially destructive or state-changing operation, but doesn't clarify what 'finalizing' entails, whether it's reversible, what permissions are needed, or what happens to the original recovery mount. The description lacks critical behavioral context for a mutation tool.

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 extremely concise - a single sentence that gets straight to the point with no wasted words. It's front-loaded with the core action and target, though this brevity comes at the cost of completeness.

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?

For a mutation tool with 2 parameters (one being a nested object), 0% schema coverage, no annotations, and no output schema, the description is severely inadequate. It doesn't explain what the tool actually does beyond the high-level concept, leaving critical gaps in understanding the operation's behavior, parameters, and outcomes.

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?

With 0% schema description coverage for both parameters (mountId and body), the description provides no information about what these parameters mean or how to use them. The description doesn't mention parameters at all, leaving the agent with no semantic understanding beyond the bare schema structure.

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 action ('Start finalizing/migrating') and target resource ('an instant-recovered VMware vSphere VM'), making the purpose understandable. However, it doesn't differentiate from sibling tools like 'InstantHvVMRecoveryMigrate' or 'AzureInstantVMRecoveryMigrate' which perform similar operations on different platforms.

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, prerequisites, or what constitutes an 'instant-recovered' VM. There are multiple sibling migration tools (e.g., for Hyper-V, Azure, unstructured data) but no indication of when this specific VMware vSphere version is appropriate.

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