MetaMCP Admin MCP

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 only states 'Create' without clarifying side effects, authorization requirements, whether the operation is atomic, or what happens to the mcpServerUuids if servers don't exist.

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?

While brief (4 words), the description is too minimal to be considered appropriately informative. It wastes the opportunity to front-load critical context, though it is not verbose or redundant.

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 4 parameters and no output schema or annotations, the description is inadequate. It fails to explain namespace semantics, relationships to servers (via mcpServerUuids), or the scope of the created resource.

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 100% schema description coverage (all 4 parameters have descriptions), the baseline is 3. The description adds no additional semantic context beyond the schema (e.g., no explanation of the relationship between namespace and mcpServerUuids, or valid instance name formats).

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 'Create a new namespace' is a tautology that restates the tool name (create_namespace → 'Create a new namespace'). It specifies the verb and resource but fails to distinguish from siblings like update_namespace or toggle_server_in_namespace, and does not explain what a namespace represents in this system.

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 provided on when to use this tool versus update_namespace, or prerequisites for creation (e.g., instance requirements). No mention of idempotency concerns or what happens if the name already exists.

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