Codex

Codex can call PlayOn tools over MCP after you mint a host token. Overview: External agents (MCP).

Before you start

1. PlayOn running with an Owner (quick start).
2. Token + MCP URL from Settings → External agents (MCP) (overview).

Wire MCP

Configure Codex’s MCP / tools settings with:

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

Use the snippet PlayOn shows after token creation when it matches your Codex version. If Codex expects a different field name for HTTP MCP, keep the same URL and Authorization header.

Example asks

Connect to PlayOn and stand up Minecraft for a LAN party: install skill, create server, start, publish player panel, give me join steps.

List servers via PlayOn MCP and stop anything that is idle.

Tips

• Network path from the Codex environment to the party box must be open.
• Revoke tokens you no longer use.
