Msty Studio

Msty Studio is a cross-platform AI chat client that supports Model Context Protocol (MCP) tools via both STDIO and Streamable HTTP connections.

Configuration

1. Open Msty Studio and go to Settings → Toolbox → Tools
2. Click Add Tool to add a new MCP server
3. Select STDIO / JSON as the connection type
4. Enter the following JSON configuration:

{
  "macuse": {
    "command": "/Applications/Macuse.app/Contents/MacOS/macuse",
    "args": ["mcp"]
  }
}

5. Click Save to apply the configuration

Verifying the Connection

1. Start a new conversation in Msty Studio
2. Ask the AI to "list available Macuse tools"
3. If configured correctly, Msty Studio will show the available toolboxes

Troubleshooting

If the connection fails:

• Ensure Macuse is installed in /Applications
• Check that Macuse has the necessary permissions enabled
• Try restarting Msty Studio after making configuration changes
