Trello MCP Server

Implementation Reference

• src/index.ts:760-816 (registration)

  Registration and inline implementation of the 'archive-cards' MCP tool. The handler archives multiple Trello cards by issuing PUT requests to set 'closed: true' for each card ID provided.

  server.tool(
  	'archive-cards',
  	{
  		cardIds: z.array(z.string()).describe('IDs of the cards to archive'),
  	},
  	async ({ cardIds }) => {
  		try {
  			if (!trelloApiKey || !trelloApiToken) {
  				return {
  					content: [
  						{
  							type: 'text',
  							text: 'Trello API credentials are not configured',
  						},
  					],
  					isError: true,
  				};
  			}
  
  			const results = await Promise.all(
  				cardIds.map(async (cardId) => {
  					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({
  								closed: true,
  							}),
  						}
  					);
  					return await response.json();
  				})
  			);
  			return {
  				content: [
  					{
  						type: 'text',
  						text: JSON.stringify(results),
  					},
  				],
  			};
  		} catch (error) {
  			return {
  				content: [
  					{
  						type: 'text',
  						text: `Error archiving cards: ${error}`,
  					},
  				],
  				isError: true,
  			};
  		}
  	}
  );

• src/index.ts:765-816 (handler)

  The handler function for 'archive-cards' tool. It performs batch archiving of Trello cards by mapping over cardIds, sending PUT /cards/{id} with closed: true, and returning JSON results.

  	async ({ cardIds }) => {
  		try {
  			if (!trelloApiKey || !trelloApiToken) {
  				return {
  					content: [
  						{
  							type: 'text',
  							text: 'Trello API credentials are not configured',
  						},
  					],
  					isError: true,
  				};
  			}
  
  			const results = await Promise.all(
  				cardIds.map(async (cardId) => {
  					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({
  								closed: true,
  							}),
  						}
  					);
  					return await response.json();
  				})
  			);
  			return {
  				content: [
  					{
  						type: 'text',
  						text: JSON.stringify(results),
  					},
  				],
  			};
  		} catch (error) {
  			return {
  				content: [
  					{
  						type: 'text',
  						text: `Error archiving cards: ${error}`,
  					},
  				],
  				isError: true,
  			};
  		}
  	}
  );
