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

The description frames the tool as purely instructional, which implies no side effects or mutations. It could be more explicit about whether the instructions are static or dynamically fetched, but for a zero-parameter informational tool this is a minor 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 a single focused sentence that communicates the tool's purpose with no filler or redundant 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?

For a parameterless informational tool, the description is mostly complete: it explains what content the tool provides and the goal of full MCP access. It could briefly note that no parameters are required or clarify its relationship to getPlatformInfo, but these omissions are not significant.

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 tool has no parameters, and the schema fully covers the parameter surface. The description does not need to document parameters; the baseline score of 4 applies.

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 tool provides instructions for registering, logging in, and obtaining an API key for MCP access. This is a specific informational purpose and is easily distinguishable from the sibling tool getPlatformInfo.

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 intended use case is implied: use this tool when the agent/user needs onboarding instructions for MCP access. However, there is no explicit guidance on when not to use it, nor any mention of the sibling tool as an alternative.

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