MCP Spotify Server

Instructions

Implementation Reference

• src/handlers/playlists.ts:22-36 (handler)

  Core handler function that implements the get_playlist_tracks tool logic by extracting the playlist ID, building query parameters, and calling the Spotify API endpoint /playlists/{id}/tracks.
  async getPlaylistTracks(args: PlaylistTracksArgs) { const playlistId = this.extractPlaylistId(args.id); const { market, limit, offset, fields } = args; const params = { market, ...(limit !== undefined && { limit }), ...(offset !== undefined && { offset }), ...(fields !== undefined && { fields }) }; return this.api.makeRequest( `/playlists/${playlistId}/tracks${this.api.buildQueryString(params)}` ); }
• src/index.ts:462-492 (registration)

  Tool registration in the MCP server's listTools response, defining the tool name, description, and input schema.
  name: 'get_playlist_tracks', description: 'Get full details of the tracks of a playlist', inputSchema: { type: 'object', properties: { id: { type: 'string', description: 'The Spotify ID or URI of the playlist' }, market: { type: 'string', description: 'Optional. An ISO 3166-1 alpha-2 country code' }, fields: { type: 'string', description: 'Optional. Filters for the query' }, limit: { type: 'number', description: 'Optional. Maximum number of tracks to return (1-100)', minimum: 1, maximum: 100 }, offset: { type: 'number', description: 'Optional. Index of the first track to return', minimum: 0 } }, required: ['id'] },
• src/index.ts:837-843 (registration)

  Dispatch handler in the callTool request that validates arguments and delegates to the playlistsHandler.getPlaylistTracks method.
  case 'get_playlist_tracks': { const args = this.validateArgs<PlaylistTracksArgs>(request.params.arguments, ['id']); const result = await this.playlistsHandler.getPlaylistTracks(args); return { content: [{ type: 'text', text: JSON.stringify(result, null, 2) }], }; }
• src/types/playlists.ts:7-10 (schema)

  TypeScript type definition for the input arguments of get_playlist_tracks, extending common market and pagination parameters.
  export interface PlaylistTracksArgs extends MarketParams, PaginationParams { id: string; fields?: string; }
• src/handlers/playlists.ts:8-10 (helper)

  Helper method used by getPlaylistTracks to normalize playlist ID from Spotify URI or plain ID.
  private extractPlaylistId(id: string): string { return id.startsWith('spotify:playlist:') ? id.split(':')[2] : id; }
