# begin_build_upload

Start uploading a READY web build of the game (static files: index.html + assets — e.g. Vite dist/, Unity WebGL) to a Title. Returns build_id, a one-hour upload_url and asset_base. Build the game with asset_base as its base path (or a relative './'), zip the CONTENTS of the output folder so index.html is at the zip root, upload it with curl -T build.zip "<upload_url>" (a plain HTTP PUT of the file, no headers), then call finish_build_upload. Needs a shell to run the upload — a browser-only client cannot upload files. Free: only the storage it takes counts toward the publisher's quota. The build must be the GAME ITSELF, hosted here: on the Title's idosgames.com page the game may embed (iframe) only platform hosts, never another website, so a wrapper that frames the publisher's own site shows "Content unavailable" there instead of the game. Network requests (fetch/WebSocket) from the embedded game reach platform hosts plus the Title's Blockchain.IframeConnectHosts (save_blockchain; wallet-connection hosts are always refused).

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",

## Why begin_build_upload is rated High

begin_build_upload triggers real processes with real consequences. An agent gone sideways doesn't fire it once. It starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.

Risk signals: Admin/system-level operation

## Use case

AI agents invoke begin_build_upload to trigger actions in iDos Games. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches iDos Games:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "begin_build_upload": {
      "limits": [
        {
          "counter": "begin_build_upload_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```
