Discord MCP Server

Instructions

Implementation Reference

• src/discord_mcp/core_tool_handlers.py:289-301 (handler)

  The core handler function that implements the remove_reaction tool logic. Fetches the Discord channel and message, removes the specified reaction added by the bot, and returns a confirmation message.

  @staticmethod
  async def handle_remove_reaction(discord_client, arguments: Dict[str, Any]) -> List[TextContent]:
      """Remove a reaction from a message"""
      channel = await discord_client.fetch_channel(int(arguments["channel_id"]))
      message = await channel.fetch_message(int(arguments["message_id"]))
      
      emoji = arguments["emoji"]
      await message.remove_reaction(emoji, discord_client.user)
      
      return [TextContent(
          type="text",
          text=f"Removed reaction {emoji} from message in #{channel.name}"
      )]

• src/discord_mcp/integrated_server.py:824-841 (schema)

  Input schema definition for the remove_reaction tool, specifying required parameters: channel_id, message_id, and emoji with their types and descriptions.

  inputSchema={
      "type": "object",
      "properties": {
          "channel_id": {
              "type": "string",
              "description": "Channel containing the message"
          },
          "message_id": {
              "type": "string",
              "description": "Message to remove reaction from"
          },
          "emoji": {
              "type": "string",
              "description": "Emoji to remove (Unicode or custom emoji ID)"
          }
      },
      "required": ["channel_id", "message_id", "emoji"]
  }

• src/discord_mcp/integrated_server.py:1021-1031 (registration)

  Registration and dispatch logic for core tools including remove_reaction. Checks if the tool name is in core_tool_names and dynamically calls the corresponding handler method on CoreToolHandlers.

  core_tool_names = [
      "get_server_info", "list_servers", "get_channels", "list_members",
      "get_user_info", "send_message", "read_messages", "add_reaction",
      "add_multiple_reactions", "remove_reaction", "moderate_message",
      "create_text_channel", "delete_channel", "add_role", "remove_role"
  ]
  
  if name in core_tool_names:
      handler_method = f"handle_{name}"
      if hasattr(CoreToolHandlers, handler_method):
          return await getattr(CoreToolHandlers, handler_method)(discord_client, arguments)

• src/discord_mcp/integrated_server.py:821-842 (registration)

  Tool object creation for remove_reaction, defining name, description, and input schema for MCP registration.

  Tool(
      name="remove_reaction",
      description="Remove a reaction from a message",
      inputSchema={
          "type": "object",
          "properties": {
              "channel_id": {
                  "type": "string",
                  "description": "Channel containing the message"
              },
              "message_id": {
                  "type": "string",
                  "description": "Message to remove reaction from"
              },
              "emoji": {
                  "type": "string",
                  "description": "Emoji to remove (Unicode or custom emoji ID)"
              }
          },
          "required": ["channel_id", "message_id", "emoji"]
      }
  ),
