Hermes Agent

Hermes Agent connects to PlayOn over MCP. After install, Hermes can install skills, create servers, and publish /play. Overview: External agents (MCP).

Before you start

1. Install PlayOn and create the Owner.
2. Mint a token under Settings → External agents (MCP) — see MCP overview.
3. Note the MCP URL and Bearer token.

Connect Hermes

Configure Hermes to use PlayOn’s Streamable HTTP MCP endpoint:

• URL: http://<host>:8787/mcp
• Header: Authorization: Bearer <token>

{
  "mcpServers": {
    "playon": {
      "url": "http://<host>:8787/mcp",
      "headers": {
        "Authorization": "Bearer playon_…"
      }
    }
  }
}

Map field names to whatever Hermes’s MCP client config expects; keep URL + Bearer auth the same.

Example asks

Use PlayOn tools to install Minecraft from the catalog, create and start a LAN server, publish /play, and summarize join info for guests.

Players can’t join the Minecraft server — inspect ports/logs with PlayOn tools and fix it.

Tips

• Hermes needs network reachability to the party box.
• Name the token Hermes in Settings so revocation is obvious later.
