Stream Deck MCP

Stream Deck MCP lets agents build and reconfigure real Elgato Stream Deck profiles.

Quick Start · Demo · Features · Tools · Development

Tell your AI what Stream Deck you want. Get back a polished profile with buttons, icons, colors, dials, touch-strip art, and the shell scripts behind it. Stream Deck MCP writes the same profile format the Elgato desktop app already uses, so agents can author real local decks without making you build a Stream Deck plugin first.

It works with Claude Desktop, Claude Code, Cursor, Codex, and any MCP client that can launch a stdio server.

Quick Start

Claude Code:

claude mcp add streamdeck -- uvx streamdeck-mcp

Claude Desktop, Cursor, Codex, and other MCP clients can use the same command:

{
  "mcpServers": {
    "streamdeck": {
      "command": "uvx",
      "args": ["streamdeck-mcp"]
    }
  }
}

Then ask your agent for a deck:

Make me a Slack control board for my Stream Deck + XL.

For Claude Code, install the bundled designer skill for better layout, palette, hardware, and plugin-action guidance:

uvx --from streamdeck-mcp streamdeck-mcp-install-skill

Features

• Profile-native authoring - reads and writes Elgato ProfilesV3 files directly, with ProfilesV2 fallback for older installs.
• Hardware inventory - discovers profile pages, device model names, key geometry, dials, and touch-strip support before writing.
• Configured action search - streamdeck_find_actions scans existing profiles/pages for paste-ready plugin buttons and dials (including protected first-party Elgato plugins configured in the app).
• Installed plugin discovery - scans readable Stream Deck plugin manifests with streamdeck_read_plugins so agents can find plugin and action UUIDs when synthesizing new actions.
• Configured plugin action reuse - prefers copying existing actions via find_actions or streamdeck_read_page's button.raw so private Property Inspector settings stay intact.
• Offline icon generation - renders button and touch-strip PNGs from about 7,400 bundled Material Design Icons, or from short text labels.
• Script-backed automations - creates executable shell scripts in ~/StreamDeckScripts/ and wires them to Stream Deck Open actions when no plugin action fits.
• Dial and touch-strip support - installs a minimal bundled Stream Deck plugin when needed so encoder imagery survives app restarts.
• Safe write cycle - guards against the Elgato app overwriting manifest edits by enforcing a quit, write, relaunch workflow.

Agentic Workflows

The point is not generic buttons. Prefer reusing actions the user already configured in the Stream Deck app (Hue, OBS, Home Assistant, Spotify plugins, etc.), then compose them onto a themed page. When your agent also has Slack, Home Assistant, OBS, GitHub, Hue, Spotify, or other MCP servers loaded, it can query those systems to pick the right entities — and still wire the deck through native plugin actions when available, falling back to scripts only when needed.

Try prompts like:

• "Make me a control board for Slack." Query channels, status, and unread state; create channel jumps, status toggles, read-all controls, and dials.
• "A hello-kitty-themed Home Assistant dashboard for the living room." Find existing HA plugin buttons with streamdeck_find_actions, then lay them out with a matching visual style — or discover living-room entities via MCP and synthesize/scripts when nothing is configured yet.
• "OBS control panel based on my actual scenes and audio inputs." Reuse configured OBS plugin actions when present; otherwise read scenes/sources and write scene switches, source toggles, and per-input dial controls.
• "A dev deck for this repo in Nordic colors." Read project scripts and GitHub context; create local command buttons, PR links, and CI shortcuts.
• "A Friday demo deck." Compose across Zoom, Slack, Hue, and screen recording by finding configured plugin actions first, then generating local scripts for the gaps.

Iteration is cheap: change the prompt, rerun the authoring flow, and get a new profile.

Install

The packaged entrypoint is streamdeck-mcp, run through uvx.

Cursor

Or paste into ~/.cursor/mcp.json:

{
  "mcpServers": {
    "streamdeck": {
      "command": "uvx",
      "args": ["streamdeck-mcp"]
    }
  }
}

Claude Desktop

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json on macOS or %APPDATA%\Claude\claude_desktop_config.json on Windows, then restart Claude Desktop:

{
  "mcpServers": {
    "streamdeck": {
      "command": "uvx",
      "args": ["streamdeck-mcp"]
    }
  }
}

Claude Code

claude mcp add streamdeck -- uvx streamdeck-mcp

OpenAI Codex

Add to ~/.codex/config.toml:

[mcp_servers.streamdeck]
command = "uvx"
args = ["streamdeck-mcp"]

Other MCP Clients

Anything that speaks MCP over stdio works the same way: point it at uvx streamdeck-mcp.

Linux and Headless Setups

The default profile writer targets the Elgato Stream Deck desktop app, which is available on macOS and Windows. On Linux, headless machines, or setups where you want the MCP server to own the hardware directly, use the legacy USB server:

uvx --from streamdeck-mcp streamdeck-mcp-usb

Client config shape:

{
  "mcpServers": {
    "streamdeck": {
      "command": "uvx",
      "args": ["--from", "streamdeck-mcp", "streamdeck-mcp-usb"]
    }
  }
}

Tools

Prompt support:

streamdeck-designer Skill

Stream Deck MCP ships with an Agent Skill for Claude Code that teaches the agent how to plan, theme, and author full decks end to end.

Install it with:

uvx --from streamdeck-mcp streamdeck-mcp-install-skill

The skill is copied to ~/.claude/skills/streamdeck-designer/. Restart Claude Code or start a new session after installing it. Re-run with --force to upgrade after a package update.

The skill covers:

• Hardware inventory and model-specific layout planning.
• Theme palettes, typography strategy, and icon-color guidance.
• Dial and touch-strip authoring for Stream Deck + and + XL devices.
• Integration recipes for Hue, OBS, Spotify, Home Assistant, Twitch, shell commands, and browser workflows.
• Existing plugin action reuse through streamdeck_find_actions and streamdeck_read_page / button.raw.

Clients that do not load Claude Code skills can invoke the design_streamdeck_deck MCP prompt instead.
