Discord Server Setup MCP

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the tool edits a channel but doesn't describe what happens if modifications fail, whether changes are reversible, what permissions are required, or the response format. For a mutation tool with 11 parameters and no annotation coverage, this is a significant gap in transparency.

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 a single, efficient sentence that front-loads the core action ('Edits an existing channel') and lists key modifiable fields. There's no wasted text, but it could be slightly more structured by separating usage context from parameter details.

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 the complexity (11 parameters, mutation operation, no output schema, and no annotations), the description is incomplete. It doesn't address behavioral aspects like error handling, authentication needs, or return values, and it lacks guidance on usage versus siblings. For a tool with this level of complexity, the description should provide more context to be fully helpful.

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 minimal parameter semantics beyond the schema, listing 'name, topic, permissions, and other settings' which maps to some of the 11 parameters. However, with 0% schema description coverage, the schema lacks descriptions for all parameters, and the description doesn't compensate by explaining key parameters like 'guildId', 'channelId', or the structure of 'permissionOverwrites'. The baseline is 3 due to the high parameter count and low coverage.

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: 'Edits an existing channel in a Discord server' with specific modifications like 'name, topic, permissions, and other settings.' It distinguishes from sibling tools like 'create_channel' and 'delete_channel' by specifying it edits existing channels. However, it doesn't explicitly differentiate from 'edit_role' or other editing tools beyond the resource type.

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?

The description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing guildId or channelId), when to choose this over 'create_channel' for new channels, or how it relates to other editing tools like 'edit_role'. Usage is implied by the verb 'edits' but lacks explicit context.

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