NVIDIA Broadcast

Purpose

NVIDIA Broadcast applies AI effects to your camera, microphone, and speaker, and can apply the same effects to local media files. You drive it over a local MCP gateway that NVIDIA Broadcast runs on loopback. It also lets you check and change AI effects, select Studio Voice microphone profiles, manage camera, microphone, and speaker devices, and change camera resolution.

Prerequisites

• Windows host with NVIDIA Broadcast installed. 2.2.x and older have no MCP gateway and cannot be driven by this skill at all. When it is missing or too old, you may offer to install it from NVIDIA's update service — see Installing or updating NVIDIA Broadcast below. Never install without asking.
• Standard executable path: %ProgramFiles%\NVIDIA Corporation\NVIDIA Broadcast\NVIDIA Broadcast.exe.
• Hermes has connected the nvidia-broadcast gateway from this plugin: its tools appear as mcp__nvidia_broadcast__* in the deferred tool catalog. See Connecting below.

Inputs

• set_effects: either effects[] with 1-32 unique effect IDs (each effectId + enabled, optional params), or action: "restore_previous_live".
• submit_file_processing: _version: 1, absolute inputPath, 1-32 unique effects[]; optional batchId, outputFolder, outputPath. There is no overwrite input — a fresh collision is rejected, while resume/retry replaces only that job's own partial output.
• list_devices: optional kind. set_active_device: kind + fresh deviceId, plus optional camera width, height, frameRate. set_camera_resolution: fresh camera deviceId, width, height, optional frameRate.
• Do not reuse device IDs from earlier sessions, and do not guess frame rates.
