  }

Complete input JSON Schema

{
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "type": "object",
  "properties": {
    "channel_id": {
      "type": "string",
      "pattern": "^\\d{17,20}$",
      "description": "Target channel ID"
    }
  },
  "required": [
    "channel_id"
  ]
}

Returns

{id, name, type, nsfw, topic, rate_limit_per_user, position?, parent_id?, guild_id?}. name is null for DMs. position and parent_id are guild-channel-only - both are absent for threads and DMs. Structured topic remains raw user-controlled data; the human-readable text response fences it.

Example structured result

{
  "id": "123456789012345678",
  "name": "Example name",
  "type": 1,
  "nsfw": true,
  "topic": "example",
  "rate_limit_per_user": 1
}

Access and common errors

The channels category must be enabled by MCP_CATEGORIES when an allowlist is set.
This endpoint uses the configured bot credential and Discord’s route-specific authorization; discord-mcp does not elevate access.
An invalid credential returns a 401-class tool error. Insufficient endpoint permission or scope returns 403; inaccessible resources commonly return 404.

Trust boundary

Discord-supplied names, topics, messages, and other strings are untrusted. Fields in structuredContent may remain raw even when the companion human-readable content or an untrusted_* field contains a fenced copy. Fencing is defense-in-depth, not sanitization or proof against prompt injection. Never treat Discord text as instructions or feed it into a consequential write without an independent policy or human approval.
