"An overview of end-to-end testing" matching MCP servers:

Enables converting text to speech audio in 20+ languages, returning base64-encoded MP3 output via Google TTS with x402 micropayment-based pay-per-call access.

Text-to-speech MCP server that enables AI assistants to read text aloud on the user's computer using Windows SAPI, with no API key or cloud service required.

Enables conversion of YouTube videos to MP3 format through the Youtube To Mp315 API. Supports checking conversion status, retrieving video titles, and asynchronous video-to-audio conversion with customizable quality and time range settings.

Enables downloading videos from platforms like YouTube and converting them to text using OpenAI Whisper and ffmpeg. It supports multiple output formats including TXT, JSON, SRT, and VTT for transcriptions.

An MCP server that provides speech-to-text transcription and speaker diarization using OpenAI Whisper and pyannote.audio.

An MCP server that enables voice-to-voice AI conversations using ElevenLabs for speech synthesis and recognition, with tools for voice management, text-to-speech, and speech-to-text.

Enables users to convert text into high-quality audio by accessing the OpenAI Text-to-Speech API. It supports customizable model selection and voice options for synthesized speech generation via the MCP protocol.

Enables MCP clients to manage Apple Music playlists end-to-end, including search, playlist creation and editing, metadata and flow auditing, track ordering optimization, and listening statistics, without an Apple Developer account.

Enables AI agents and MCP clients to drive Ableton Live 12 end to end, from setting tempo and building instruments through writing MIDI, arranging, mixing, bouncing and mastering. Adds real-time rendering plus loudness and spectral analysis and multi-format encoding with tags and artwork, for turning an empty set into a release-ready track.

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

A server that generates MP3 audio files from text using Kokoro TTS technology with optional S3 upload capabilities.

Enables end-to-end control of FL Studio on macOS through MCP clients, including transport, patterns, mixer, piano roll, playlist, live metering, browser navigation, and rendering.

Enables Claude to search SoundCloud, curate and build playlists from a described mood or moment, and control playback by playing, skipping and liking songs. It also exposes the local desktop player's library and queue so requests like "make me something for a rainy afternoon and play it" are carried out end to end.

Enables Claude or any MCP client to produce full tracks in Ableton Live from chat: building tracks, writing MIDI notes, loading and tweaking device parameters, arranging sections, and drawing real clip and Arrangement automation. It also exposes mixer state snapshots and clip editing so a live set can be inspected and reshaped end to end.

Enables MCP clients such as Claude to generate spoken audio locally, narrating English with Kokoro and Malayalam with IndicF5, Parler-TTS, Piper or MMS, including cloned Malayalam voices, pronunciation lexicons, and number/currency expansion. Outputs loudness-normalised WAV or MP3 and runs long narrations through a pollable job queue so tool calls never time out.

Enables submitting audio via URL or Base64 for local Whisper transcription, then checking job status and results or deleting transcription jobs. It provides asynchronous job handling and SSRF-protected downloads/callbacks without cloud API calls.

An MCP server that enables analysis of local media files, including video, audio, and documents, by uploading them to EnriProxy for server-side extraction. It supports various complex file formats and provides structured model analysis for media types often unsupported by standard MCP clients.

Facilitates the creation of DecentSampler drum kit configurations, supporting WAV file analysis and XML generation to ensure accurate sample lengths and well-structured presets.

Enables downloading media and precise clips from 1000+ sites via yt-dlp, with tools for inspecting media, downloading full videos/audio, and clipping by start/end times.

An official MCP server for Online Tone Generator. Discover audio frequencies for instrument tuning, acoustic testing, meditation, and generate direct listening links.
