# Declarative MCP over stdio — a RUNNABLE transport proof, no network and
# no credentials: the platform spawns `examples/mcp_stdio_server.py` as a
# subprocess on the tool's first call (lazy connect), and the session
# lives on a dedicated event loop (the 0.9.0 session-lifecycle fix; this
# transport failed on every call before).
