Utilizes the grandMA3 MCP server to patch fixtures, execute console commands, and trigger macros via OSC.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# grandMA3 MCP — Integration and AI Agent Guide This skill file instructs AI agents on how to control grandMA3 lighting consoles using the `grandma3_mcp.py` script. It details OSC routing, command execution, fixture patching, and troubleshooting steps. ## 1. Overview and Pipeline Value The **grandMA3 MCP Server** enables AI models to programmatically configure and drive grandMA3 lighting control software. In the BDB OS workflow, this integration automates fixture patching, triggers lighting states, executes macros, and manages live cue sequencing during stage productions. ### Architecture - **FastMCP server:** Implements standard Model Context Protocol. - **OSC UDP Transport:** Sends network packets via Open Sound Control (OSC) to `127.0.0.1` on port `8000`. - **Command Router:** Maps JSON-RPC requests to OSC `/cmd` string paths, executing them natively inside grandMA3's Command Line. --- ## 2. System Instructions ### Workflow Priorities 1. **Target Port Configuration:** Ensure grandMA3's OSC settings are configured to listen on port `8000` and route `/cmd` addresses. …

How to install
mdr add hybridlabor-api/aos/bdb-grandma3-mcp@sha256:ecfbe2ce6d69875dThe line at the top of this page pins the label git:20260912.75929c4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
