An MCP server for Pangolin BEYOND laser software. Exposes 117 tools across 20 categories covering show control, cue management, zone configuration, geometric correction, live parameter control, effects, projector alignment, safety limiters, and more — all via OSC.

Built for live production. Pairs with grandMA2 MCP, Resolume MCP, MADRIX MCP, and Companion MCP for full AI-driven show control.

Why this exists

Pangolin BEYOND is the industry-standard laser show software, but programming laser cues, adjusting zones, and tuning live parameters is entirely manual. An operator clicks through the BEYOND UI, one parameter at a time, across dozens of zones and cues.

This MCP server lets an AI assistant control BEYOND over OSC. It can trigger cues, adjust master brightness, mute zones, set BPM, control projector alignment, apply geometric corrections, manage safety limiters, and control live parameters — all from a single conversation. Combined with MA2 Agent, Resolume MCP, and Companion MCP, an AI assistant can orchestrate the entire show control stack.

Quick start

git clone https://github.com/drohi-r/beyond-mcp && cd beyond-mcp
uv sync
uv run python -m beyond_mcp

Make sure BEYOND is running with OSC input enabled (configurable via BEYOND_OSC_PORT, defaults to 12000).

For remote control:

• use LAN or WireGuard, not the public internet
• allow UDP to BEYOND_OSC_PORT
• set BEYOND_HOST to the remote machine and include it in BEYOND_ALLOWED_HOSTS

Live-Validated Build Notes

This repo has been exercised against a real BEYOND instance over LAN, not only mocked unit tests.

Live-confirmed tools on the validated build:

• display_popup
• set_bpm
• select_next_page / select_prev_page
• select_next_tab / select_prev_tab
• start_cue_by_name / stop_cue_by_name
• set_master_brightness

Build-specific notes:

• load_cue sent cleanly but did not produce an obvious visible state change in the tested workspace.
• display_preview("main", ...) sent cleanly, but main did not appear to be the correct preview identifier for the validated BEYOND setup.

Safety profiles

BEYOND_SAFETY_PROFILE gives you a sane starting point without having to remember multiple flags:

• lab
  • read_only = false
  • confirm_destructive = false
• show-safe
  • read_only = false
  • confirm_destructive = true
• read-only
  • read_only = true
  • confirm_destructive = true

Explicit environment flags still win if you need to override the profile:

BEYOND_SAFETY_PROFILE=show-safe \
BEYOND_CONFIRM_DESTRUCTIVE=0 \
uv run python -m beyond_mcp

Codex

Create a codex.json MCP config file:

{
  "mcpServers": {
    "beyond": {
      "command": "uv",
      "args": ["run", "--directory", "/path/to/beyond-mcp", "python", "-m", "beyond_mcp"],
      "env": {
        "BEYOND_HOST": "127.0.0.1",
        "BEYOND_OSC_PORT": "12000"
      }
    }
  }
}

Then run Codex with:

codex --mcp-config codex.json

Production safety

This server is designed for live show environments where accidental commands can disrupt a running laser show. All 117 tools include full parameter validation.

• UDP fire-and-forget -- BEYOND OSC control uses UDP, meaning commands are sent without acknowledgement. There is no rollback. Every tool call is a real action on the laser system.
• Host allowlisting -- only 127.0.0.1, localhost, and ::1 are permitted by default. Add LAN hosts explicitly via BEYOND_ALLOWED_HOSTS. Set * to allow any host.
• Read-only mode -- set BEYOND_READ_ONLY=1 to block all write operations. Only get_server_config, health_check, preview_osc, and preview_osc_bundle remain available.
• Confirm-destructive gating -- set BEYOND_CONFIRM_DESTRUCTIVE=1 to require confirm=true on destructive operations, including raw/bundle sends of destructive OSC addresses and disruptive named tools like load_workspace, stop_zone, and stop_projector_by_name.
• Health check -- health_check verifies BEYOND target reachability via DNS resolution and UDP socket test and reports the resolved address family/socket target.
• OSC bundle support -- send_osc_bundle sends multiple OSC messages as an atomic bundle, ensuring all-or-nothing delivery for coordinated multi-parameter changes.
• Preview before send -- preview_osc and preview_osc_bundle return the exact packet details without transmitting anything. Use them before high-risk live operations.
• Input validation -- all 117 tools with documented parameter ranges enforce bounds before any OSC message is built. Brightness, zoom, scan rate, size, position, rotation, color, BPM, speed, fade times, effect slots, limiter types, geometric correction parameters, and non-negative indexes are all range-checked. Invalid inputs return structured JSON errors, never raw exceptions.
• Error isolation -- all tools are wrapped in _handle_errors. OSC send failures, JSON parse errors, validation failures, and unexpected exceptions return {"ok": false, "error": "...", "blocked": true} instead of crashing the MCP session.
• Transport validation -- only stdio, sse, and streamable-http transports are accepted. Invalid transport values raise immediately at startup.
• Port validation -- BEYOND_OSC_PORT is validated as an integer in the 1-65535 range at config load time.
• Raw escape hatch -- send_osc_raw allows any OSC address for coverage beyond the named tools, but requires explicit JSON array input and validates structure before sending.

Suggested Operator Flow

For first use on a new BEYOND machine:

1. get_server_config
2. health_check
3. display_popup
4. set_bpm
5. page/tab navigation
6. non-critical cue start/stop
7. live parameter tests like master brightness
