Discord Management MCP

Set Discord voice channel status

discord_set_voice_channel_status

Set or clear the status text displayed on a Discord voice channel, letting you show current activity or remove outdated status. The bot must have permission to manage the channel.

Instructions

Set or clear the status text shown on a voice channel. Uses the Discord REST voice-status endpoint and requires the bot to be allowed to manage the channel.

TDQS

B3.2/5.0
Behavior3/5

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

Annotations already declare non-read-only, open-world, non-destructive and non-idempotent behavior, so the base bar is lower. The description adds a real permission prerequisite (bot must be allowed to manage the channel) and names the REST endpoint, but says nothing about the confirm gate or the audit-log reason, which are meaningful behavioral facts for a mutation.

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?

Two short sentences, no filler, with the action and its scope front-loaded before the prerequisite. Nothing redundant is present; the issue is omission, not verbosity.

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

Completeness2/5

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

For a four-parameter mutation with zero schema descriptions and a confirm gate, the description is far too thin. The existence of an output schema excuses it from explaining return values, but the confirm and reason parameters remain completely unexplained.

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

Parameters2/5

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

Schema description coverage is 0% across four parameters, so the description must compensate and does not. It never mentions channelId, the 1–500 character status limit, the confirm flag, or the 512-character audit-log reason — all of which an agent must infer from bare JSON Schema types.

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

Purpose4/5

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

The description gives a specific verb pair (set or clear) applied to a specific resource (voice channel status text), and the 'clear' clause signals the null case in the schema. It is clear enough to distinguish this from discord_update_channel, though it never names that sibling explicitly.

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?

Usage is only implied by 'set or clear' and the 'requires the bot to be allowed to manage the channel' prerequisite. There is no guidance on when to prefer this over discord_update_channel, and no explanation of when to pass status=null versus a string.

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