unity_transport

unity_transport is a cursor rule for Cursor from muammar-yacoob/unity-mcp. It costs 385 tokens per session, scanned A, original, MIT.

A set of rules for choosing and using HTTP or WebSocket connections in a Unity MCP integration. It keeps both connection types behind the same interface and configuration.

In plain words
What is it for?
Use it when adding or changing Unity MCP transports, configuring ports and timeouts, or keeping new transport implementations compatible with existing code.
Why use it?
It prevents connection settings from being scattered through the code and makes failures, reconnects, and disconnects easier to understand.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

unity_transport scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

  • Use TransportFactory.create for runtime selection
    • Honour UNITY_MCP_TRANSPORT, UNITY_MCP_HTTP_PORT, UNITY_MCP_WS_PORT, and UNITY_MCP_TIMEOUT environment variables as illustrated in factory.ts; avoid hard-coding ports elsewhere.
  • Surface connection diagnostics via stderr
    • Log chosen transport and reconnect attempts with console.error following the patterns in factory.ts and websocket.ts to keep MCP output channels clean.
  • Wrap transport failures with actionable errors
    • Convert axios and WebSocket failures into descriptive Error instances (see HttpTransport.request and WebSocketTransport.handleMessage) so upstream services can compose user-friendly responses.
  • Guard WebSocket lifecycle transitions
    • Reuse the connect promise and reject pending requests on disconnect before retrying, mirroring the state machine in websocket.ts when extending behaviour.
  • Keep ITransport contract intact
    • Ensure new transports implement the same request, isConnected, connect, disconnect, and getType methods defined in ITransport.ts for drop-in compatibility.
const transport = TransportFactory.create({ type: 'http', timeout: 15000 });
await transport.connect();
const result = await transport.request("/asset/refresh", {});
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
