Discord Server Setup MCP

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

With no annotations provided, the description carries full burden. It mentions this is a 'comprehensive operation that will add many elements,' hinting at mutation, but doesn't disclose critical behavioral traits like required permissions, whether changes are reversible, rate limits, or what happens if elements already exist. For a 5-parameter mutation tool, this is inadequate.

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?

Two sentences that are front-loaded with the core purpose. The second sentence adds useful context about comprehensiveness. No wasted words, though it could be slightly more structured with bullet points for clarity.

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 complexity (5 parameters, mutation operation, no annotations, no output schema), the description is incomplete. It lacks details on parameter usage, behavioral constraints, error handling, and output format. For a tool that modifies server structure, this leaves significant gaps for an AI agent.

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 description coverage is 0%, so the description must compensate. It mentions creating roles, categories, and channels, which loosely relates to templateId, but doesn't explain guildId, skipRoles, skipCategories, or validate parameters. The description adds minimal semantic value beyond what's inferable from parameter names.

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 verb ('applies') and resource ('template to a Discord server'), specifying it creates roles, categories, and channels. It distinguishes from siblings like create_category or create_role by indicating this is a comprehensive batch operation. However, it doesn't explicitly contrast with preview_template, which might be a closer alternative.

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 explicit guidance on when to use this tool versus alternatives like preview_template or individual creation tools. The description implies it's for bulk operations but doesn't state prerequisites, exclusions, or recommend when to use skipRoles/skipCategories parameters.

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