CuePilot MCP is a source-available MCP server for vMix from Greenhouse Labs. It gives AI assistants read-first production intelligence for live-production workflows: inspecting vMix state, explaining presets, diagnosing audio and routing issues, reviewing scripts, generating show checklists, and producing reviewable automation plans before anything changes in vMix.
The public launch is being prepared now. The GitHub repository remains private and the npm package is not published yet, so setup commands are shown as release-preview references until npm is public.
Why It Exists
AI assistants can be useful in live production, but only if they understand the show before trying to change it. CuePilot MCP starts with Review Mode: read the current state, separate observed facts from assumptions, explain the setup in operator language, and produce reviewable next steps.
What It Reviews
- Current vMix state, inputs, active and preview paths, overlays, title fields, and tally
- Audio routing, buses, mutes, solo state, vMix Call patterns, and mix-minus risks
- Recording, streaming, external output, video path, audio path, and destination blind spots
- Saved
.vmixpreset files, scripts, triggers, saved-vs-live drift, and redacted preset metadata - VB.NET scripts and API plans before they are copied into an operator workflow
- Connection issues, pasted logs, and safe next checks without exposing production secrets
Safety Model
Review Mode is the default. It inspects, explains, diagnoses, validates, and plans without executing scripts, calling vMix shortcut functions, saving presets, starting streams, changing audio, or mutating the show.
Control Mode is available only when an operator explicitly enables VMIX_CONTROL_MODE=true. High-Impact Control requires both VMIX_CONTROL_MODE=true and VMIX_HIGH_IMPACT=true for workflows such as recording, streaming, batch commands, scripts, presets, output routing, destructive input changes, and show-building.
Example Workflows
- Explain the current show like a technical director preparing for rehearsal.
- Diagnose remote guest audio and flag likely mix-minus problems.
- Review whether recording, streaming, and external outputs are ready for operator verification.
- Generate a safe lower-third API plan without executing it.
- Validate a vMix VB.NET script before pasting it into vMix.
- Compare before and after XML snapshots and summarize the production meaning of the change.
Launch Notes
CuePilot MCP will launch under the Greenhouse Labs brand and is legally owned and licensed by Greenhouse Ventures LLC. It is source-available, not open source. It is an independent integration for vMix workflows and is not affiliated with, endorsed by, or sponsored by vMix or StudioCoast Pty Ltd.
