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 'Update' implies a mutation operation but fails to describe critical traits: whether this requires administrative permissions, if it's idempotent, what happens on failure (e.g., license invalidation), or typical response formats. For a mutation tool with zero annotation coverage, this lack of behavioral context is a significant gap.

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 with no wasted words. It is front-loaded with the core action ('Update the Veeam license'), though this brevity comes at the cost of completeness. Every word earns its place by stating the basic purpose, but it lacks necessary elaboration.

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 (a mutation operation with 1 nested object parameter, 0% schema coverage, no annotations, and no output schema), the description is severely incomplete. It does not compensate for the missing structured data: no parameter details, no behavioral context, no usage guidelines, and no output information. This is inadequate for a tool that modifies critical licensing data.

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% schema description coverage, meaning the parameter is entirely undocumented in the schema. The description adds no information about parameter semantics—it does not explain what the 'body' object should contain (e.g., license key, expiration date, features), expected formats, or examples. With low coverage and no compensation in the description, parameter understanding is inadequate.

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 'Update the Veeam license' is a tautology that merely restates the tool name 'UpdateLicense' with minimal elaboration. While it identifies the verb ('Update') and resource ('Veeam license'), it lacks specificity about what aspects of the license can be updated or how this differs from sibling tools like 'InstallLicense', 'RemoveLicense', or 'RenewInstalledLicense'. The purpose is vague beyond the basic action.

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. It does not mention prerequisites (e.g., needing an existing license to update), exclusions, or comparisons to sibling tools such as 'InstallLicense' (for new licenses) or 'RenewInstalledLicense' (for renewal). Without any usage context, an agent cannot determine appropriate scenarios for invocation.

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