Superset MCP Integration

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

With no annotations provided, the description carries full burden but offers minimal behavioral insight. It mentions the API endpoint and return type ('A dictionary with user role information'), but lacks details on authentication requirements, error handling, rate limits, or whether this is a read-only operation. The phrase 'Get roles for the current user' implies a read operation, but this isn't explicitly stated.

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 concise, with three sentences that each add value: stating the purpose, specifying the API endpoint, and describing the return type. There's no wasted text, though it could be slightly more front-loaded by integrating the return info earlier.

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 simple read tool with no parameters and no output schema, the description is adequate but incomplete. It covers the basic purpose and return format, but lacks context on authentication needs, error cases, or how the returned dictionary is structured. Without annotations or output schema, more behavioral detail would improve completeness.

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 0 parameters, and schema description coverage is 100% (empty schema). The description doesn't need to explain parameters, so it appropriately avoids redundant information. A baseline of 4 is applied since no parameters exist to document.

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's purpose: 'Get roles for the current user' specifies the verb (get) and resource (roles), and 'Makes a request to the /api/v1/me/roles/ endpoint' provides implementation context. However, it doesn't explicitly differentiate from sibling tools like 'superset_user_get_current', which might retrieve different user information.

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 is provided on when to use this tool versus alternatives. The description doesn't mention prerequisites (e.g., authentication), compare it to similar tools like 'superset_user_get_current', or specify scenarios where retrieving user roles is appropriate versus other user-related operations.

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