Enables free Spotify accounts to read Liked Songs, search the full catalog, and control playback across any Spotify Connect device such as Chromecast, TV, phone, or desktop without Premium.

Enables Claude AI to control Ableton Live and Max for Live, allowing music production tasks like track management, MIDI editing, and pattern generation directly from conversation.

Enables AI agents to perform local video, audio, and file operations inside an isolated workspace, including cutting/concat videos, extracting audio, transcribing, and managing files, with typed responses and background job support.

A MCP server for accessing Zoom recordings and transcripts without requiring direct authentication from the end user.

Enables seamless integration with Typecast API through the Model Context Protocol, allowing clients to manage voices, convert text to speech, and play audio in a standardized way.

An MCP server enabling video processing via natural language: transcription with Whisper, segment cutting with FFmpeg, and file management.

Provides LLMs with full access to the Ken Video API for professional video processing, including adding audio, captions, and job management.

Enables AI-assisted MIDI music generation and composition through natural language, supporting style, tempo, key, and instrument selection.

Enables bounded, schema-validated automation of FMOD Studio game audio through MCP/CLI workflows, including inspection, safe mutations, previews, receipts, and high-level workflows for events, assets, parameters, adaptive music, spatial audio, banks, and mixer/routing.

MCP server providing tools to fetch YouTube video transcripts with metadata, supporting direct YouTube transcripts and audio transcription via multiple backends (whisper, AssemblyAI, OpenAI, Gemini).
