  async ({ cardId, listId, position = 'bottom' }) => {
  	try {
  		const response = await fetch(
  			`https://api.trello.com/1/cards/${cardId}?key=${trelloApiKey}&token=${trelloApiToken}`,
  			{
  				method: 'PUT',
  				headers: {
  					'Content-Type': 'application/json',
  				},
  				body: JSON.stringify({
  					idList: listId,
  					pos: position,
  				}),
  			}
  		);
  		const data = await response.json();
  		return {
  			content: [
  				{
  					type: 'text',
  					text: JSON.stringify(data),
  				},
  			],
  		};
  	} catch (error) {
  		return {
  			content: [
  				{
  					type: 'text',
  					text: `Error moving card: ${error}`,
  				},
  			],
  			isError: true,
  		};
  	}
  }

• src/index.ts:243-247 (schema)

  Zod schema defining the input parameters for the move-card tool: cardId, listId, and optional position.

  {
  	cardId: z.string().describe('ID of the card to move'),
  	listId: z.string().describe('ID of the destination list'),
  	position: z.string().optional().describe('Position in the list (e.g. "top", "bottom")'),
  },

• src/index.ts:241-284 (registration)

  Registration of the 'move-card' tool using server.tool(), including schema and handler.

  server.tool(

  	{
  		cardId: z.string().describe('ID of the card to move'),
  		listId: z.string().describe('ID of the destination list'),
  		position: z.string().optional().describe('Position in the list (e.g. "top", "bottom")'),
  	},
  	async ({ cardId, listId, position = 'bottom' }) => {
  		try {
  			const response = await fetch(
  				`https://api.trello.com/1/cards/${cardId}?key=${trelloApiKey}&token=${trelloApiToken}`,
  				{

  				content: [
  					{
  						type: 'text',
  						text: JSON.stringify(data),
  					},
  				],
