## Common questions

### What is the MCP Audio Studio server?

MCP Audio Studio is listed in the public MCP registry as io.github.mario-andreschak/mcp-audio-studio. A digital audio workstation MCP App with sequencing, mixing, effects, automation, and rendering. This page covers its npm package (mcp-audio-studio).

### Is the MCP Audio Studio server safe to use?

MCP Audio Studio scores 82 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 24 September 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the MCP Audio Studio server expose?

MCP Audio Studio exposes 29 tools: studio_ui, get_project, new_project, set_project, set_transport, and 24 more. Their descriptions and schemas cost roughly 1,662 tokens of context every time the server is loaded.

### Is the MCP Audio Studio server still maintained?

MCP Audio Studio is still listed as active in the MCP registry. We last reached this channel on 24 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the MCP Audio Studio server under?

MCP Audio Studio declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
