"""OpenAI Agents SDK (Python) + the nine AgentGate tools as remote MCP servers.

Free tier, no wallet, no API keys for the tools. Each server is plain
Streamable HTTP MCP, so the SDK's MCPServerStreamableHttp connects directly.

    pip install -r requirements.txt
    python trust_kit_agent.py --list                 # connect + list every tool, no LLM call
    python trust_kit_agent.py --smoke                # also call two free tools directly, no LLM call
    OPENAI_API_KEY=sk-... python trust_kit_agent.py "Is 0x098B716B8Aaf21512996dC57EB0615e2383E2f96 safe to pay?"

Pick a subset with TOOLS=payguard,signcheck,webread. The free MCP tools return
the preview verdict; each answer names the paid x402 endpoint (USDC on Base)
for the full report, see ../python/pay_one_tool.py to pay one.
