Implementation Reference
- The main handler function that executes the likeTweet tool: checks for client, gets current user ID, calls Twitter API v2.like(userId, tweetId), and returns success message or formatted error.
export const handleLikeTweet: TwitterHandler<TweetEngagementArgs> = async ( client: TwitterClient | null, { tweetId }: TweetEngagementArgs ): Promise<HandlerResponse> => { if (!client) { return createMissingTwitterApiKeyResponse('likeTweet'); } try { const { data: { id: userId } } = await client.v2.me(); await client.v2.like(userId, tweetId); return createResponse(`Successfully liked tweet: ${tweetId}`); } catch (error) { if (error instanceof Error) { throw new Error(formatTwitterError(error, 'liking tweet')); } throw error; } }; - src/tools.ts:35-44 (schema)Tool schema definition for likeTweet, including description and inputSchema requiring tweetId string.
likeTweet: { description: 'Like a tweet by its ID', inputSchema: { type: 'object', properties: { tweetId: { type: 'string', description: 'The ID of the tweet to like' } }, required: ['tweetId'], }, }, - src/index.ts:182-185 (registration)Tool dispatch/registration in the main MCP server request handler: extracts tweetId from arguments and calls handleLikeTweet.
case 'likeTweet': { const { tweetId } = request.params.arguments as { tweetId: string }; response = await handleLikeTweet(client, { tweetId }); break; - src/types.ts:41-43 (schema)TypeScript interface defining input args for likeTweet: tweetId string.
export interface LikeTweetArgs { tweetId: string; } - src/types.ts:248-255 (helper)Runtime validation helper function to assert arguments match LikeTweetArgs interface.
export function assertLikeTweetArgs(args: unknown): asserts args is LikeTweetArgs { if (typeof args !== 'object' || args === null) { throw new Error('Invalid arguments: expected object'); } if (!('tweetId' in args) || typeof (args as any).tweetId !== 'string') { throw new Error('Invalid arguments: expected tweetId string'); } }
