Atlas Cloud MCP Server (Image / Video / LLM APIs)

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description adds valuable behavioral context beyond annotations: it discloses that uploaded files are temporary ('may be cleaned up periodically'), warns against abuse ('bulk uploads unrelated to generation tasks may result in API key suspension'), and clarifies the tool's intended scope ('for temporary use with Atlas Cloud generation tasks only'). Annotations provide basic hints (e.g., not read-only, not destructive), but the description enriches this with practical constraints and consequences.

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 well-structured and front-loaded with the core purpose, followed by usage guidelines, important warnings, and examples. Every sentence serves a clear purpose—explaining the tool's role, workflow, constraints, and parameters—with no redundant or unnecessary information.

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 file upload with behavioral constraints) and the absence of an output schema, the description provides comprehensive context: it explains the purpose, usage workflow, supported file types, important limitations, and return value. The annotations cover basic hints, but the description fills in critical details about temporary storage and usage restrictions, making it complete for an agent to use effectively.

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 schema description coverage is 100%, with the parameter 'file_path' fully documented in the schema as 'Absolute path to the local file to upload'. The description repeats this in the Args section but adds no additional semantic meaning beyond what the schema already provides. This meets the baseline score of 3 for high schema coverage.

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 specific action ('Upload a local image or media file to Atlas Cloud') and the resource ('get a publicly accessible URL'). It distinguishes this tool from siblings by explicitly mentioning its role in workflows with atlas_generate_image, atlas_generate_video, and atlas_quick_generate, which are all sibling tools.

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 explicit guidance on when to use this tool ('when you need to provide an image URL... but only have a local file path') and includes a clear workflow with step-by-step instructions. It also specifies when NOT to use it ('Do NOT use this as a permanent file hosting service') and mentions alternatives implicitly by listing the tools that should use the returned URL.

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