Implementation Reference

  • Registration and handler implementation for the dex_get_current_user tool.
    export function registerUserTools(server: McpServer): void {
      server.tool(
        "dex_get_current_user",
        "Retrieve the profile of the currently authenticated user including name, email, time zone, and subscription plan.",
        {},
        async () => {
          try {
            const result = await dex.get("/v1/users/me");
            return toResult(result);
          } catch (error) {
            return toError(error);
          }
        }
      );
    }
Behavior2/5

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

No annotations are provided, so the description carries full burden. It mentions retrieval of profile data but lacks details on behavioral traits such as authentication needs (implied but not stated), rate limits, error conditions, or response format. This is a significant gap for a tool with no annotation coverage.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence that front-loads the key action and details. There is no wasted text, and it directly communicates the tool's purpose and scope without unnecessary elaboration.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (0 parameters, no output schema, no annotations), the description is adequate but incomplete. It covers the purpose and data retrieved but lacks behavioral context (e.g., authentication, errors) and output details, which are needed for full understanding despite the low complexity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has 0 parameters with 100% schema description coverage, so no parameter information is needed. The description does not add parameter semantics, but this is acceptable given the baseline. It implies no inputs are required, which aligns with the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the specific action ('Retrieve') and resource ('profile of the currently authenticated user'), and distinguishes it from sibling tools by focusing on the current user rather than contacts, groups, or other entities. It specifies what information is included (name, email, time zone, subscription plan).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage context by mentioning 'currently authenticated user,' suggesting it should be used when needing the caller's own profile. However, it does not explicitly state when to use this tool versus alternatives (e.g., dex_get_contact for other users) or any prerequisites like authentication requirements.

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