What it does

Bridges AI assistants to Elgato devices such as the Stream Deck. A narrow and slightly delightful entry: physical buttons controlled by a conversation. Listed because official hardware servers are rare and because the pattern — desktop peripherals as agent tools — is likely to spread.

Install

Terminal

npx -y @elgato/mcp-server

Client configuration

Paste this into your MCP client config (Claude Desktop, Cursor, or any client that reads mcpServers), then restart the client.

mcp.json

{
  "mcpServers": {
    "elgato": {
      "command": "npx",
      "args": [
        "-y",
        "@elgato/mcp-server"
      ]
    }
  }
}

Server automation; this is desk hardware

When to use it

Reach for this when the task needs hardware inside the agent loop. Skip it if a plain shell command or a one-off script is enough — every server you add costs context and adds a failure mode.

Other TypeScript servers

Filesystem — Gives an agent scoped read, write, and search access to directories you explicitly allow
Memory — A persistent knowledge graph stored in a local JSON file, exposed through entities, relations, and observations
Sequential Thinking — Gives the model a scratchpad for structured, revisable reasoning: numbered thoughts that can branch, revise, and conclude
