Aedifion MCP Server

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

No annotations provided. Description mentions 'logged-in user' indicating authentication scope, but fails to disclose mutation semantics: partial update behavior (both params nullable/optional), what null values do (clear vs unchanged), or output structure despite having an output schema.

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?

Efficient three-line structure with clear intent stated upfront. The 'Args:' block is somewhat unconventional for MCP but conveys parameter semantics concisely. No redundant text.

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?

Adequate for a 2-parameter tool with output schema covered elsewhere. Acceptable baseline coverage, though missing partial-update semantics and null-handling behavior that would complete the behavioral contract.

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?

Schema has 0% description coverage (only titles). Description compensates minimally by identifying parameters as 'New first name' and 'New last name', adding semantic value beyond schema titles. However, fails to explain the nullable anyOf types, default null behavior, or partial update capability.

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?

Clearly identifies the operation (Update) and target resource (logged-in user's details). Scope restriction to 'logged-in user' distinguishes from potential admin update tools. Deducted one point for not specifying that only name fields are updatable, leaving the 'details' scope vague.

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 on when to use this versus create_user, nor does it mention that all parameters are optional (0 required) enabling partial updates. No prerequisites or error conditions mentioned.

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