Switching from Msty
01
Install ToolPiper
Free, with no account. It runs on Apple Silicon Macs with macOS 26 or later.
02
Adopt the models you have
ToolPiper finds Ollama, LM Studio, Jan and Hugging Face cache libraries on your Mac and asks once to adopt them. Each GGUF is hardlinked into its own store, so nothing is copied or downloaded again.
03
Point your apps at it
Apps that speak the OpenAI API work with ToolPiper's local OpenAI-compatible API, and MCP clients such as Claude Code and Cursor connect to its MCP server.

Common questions
Is Msty free?
Yes. Msty Studio's Free plan is $0, and local chat on Studio Desktop needs no account. Aurum adds workspace features at $149 per user a year, or $349 per user once for a lifetime license, as published on 2026-10-09.
Is ToolPiper free?
Yes. The whole runner is free with no account and no caps: the llama.cpp engine, unlimited model downloads, the local OpenAI-compatible API, all speech and the MCP host. Paid plans start at $10/mo with Pro, which adds browser automation, files and Git, and RAG over your files.
Is Msty an Ollama wrapper?
No. Msty Studio installs and supervises three local engines as background services: Ollama, which it labels Local AI, llama.cpp and MLX, and it generally recommends MLX on Apple Silicon. It manages engines that other teams build. ToolPiper takes the other approach and runs upstream llama.cpp inside the app.
Msty or LM Studio?
Msty Studio is a chat workspace that manages Ollama, llama.cpp and MLX for you, built around Split Chats for comparing models side by side. LM Studio is a model runner with its own model search and a local server. Both are free for local use. ToolPiper is the one to pick when you also want speech in both directions and an MCP server that serves tools to your agents.
Does Msty have an MCP server?
Msty Studio's Toolbox connects to MCP servers over STDIO and Streamable HTTP. Msty Go exposes a local endpoint, and Msty Nexus is a gateway through which approved clients discover and call tools from other integrations. ToolPiper serves its own tools to Claude Code, Cursor and other MCP clients, and hosts any MCP server.
Can Msty do voice?
Msty Go ships on-device speech-to-text. Msty Studio documents no local speech-to-text or text-to-speech. ToolPiper's free tier includes dictation, transcription, text-to-speech, voice cloning and voice chat.
