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 states 'Renew' which implies a mutation operation, but doesn't describe what 'renew' entails (e.g., extending expiration, updating keys), whether it requires specific permissions, what happens on failure, or if it's idempotent. For a mutation tool with zero annotation coverage, this is a significant gap in transparency.

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 with zero wasted words. It's appropriately sized for a simple tool and front-loads the core action clearly.

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 (mutation operation with 1 nested parameter), lack of annotations, 0% schema coverage, and no output schema, the description is inadequate. It doesn't explain what 'renew' means operationally, what inputs are required, what the outcome is, or how it differs from sibling license tools, leaving critical gaps for an agent to use it correctly.

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 ('body') with 0% description coverage and no details in the schema. The description provides no information about what parameters are needed (e.g., license key, renewal duration) or their semantics. With low schema coverage, the description fails to compensate, leaving parameters completely undocumented.

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 ('Renew') and the resource ('the installed license on the Veeam Backup server'), providing a specific verb+resource combination. However, it doesn't differentiate from sibling tools like 'InstallLicense', 'UpdateLicense', or 'RemoveLicense', which would require explaining what 'renew' means specifically versus those alternatives.

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 like 'InstallLicense' or 'UpdateLicense', nor does it mention prerequisites (e.g., whether a license must already be installed). It only states what the tool does without context for selection among similar tools.

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