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 but lacks critical behavioral details. It states it 'Updates multiple server settings' which implies mutation, but doesn't disclose required permissions, whether changes are reversible, rate limits, or what happens to unspecified settings. This is inadequate for a mutation tool with zero 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.

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

Two concise sentences with zero waste. The first establishes the core action and scope, the second enumerates modifiable fields. Every word contributes directly to understanding the tool's functionality.

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 mutation tool with 6 parameters, 0% schema description coverage, no annotations, and no output schema, the description is insufficient. It covers what settings can be modified but lacks behavioral context, parameter details for guildId, enum explanations, and response format information.

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 description adds significant value beyond the schema by listing the specific settings that can be modified (name, description, verification level, content filter, default notifications), which corresponds to 5 of the 6 parameters. With 0% schema description coverage, this effectively documents most parameters, though it doesn't explain the guildId parameter or enum values.

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 ('Updates') and resource ('server settings'), and specifies the scope ('multiple... at once') with a list of modifiable fields. It distinguishes from siblings like set_content_filter or set_verification_level by indicating it can modify multiple settings simultaneously, though it doesn't explicitly name alternatives.

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 single-setting alternatives like set_content_filter or set_verification_level. The description implies it's for bulk updates but doesn't specify prerequisites, constraints, or trade-offs compared to other tools.

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