Parallel Fleet Operations

Runtime and discovery

Use the modern pyATS MCP Streamable HTTP server. For stateless HTTP set PYATS_MCP_TRANSPORT_MODE=stateless on the server. Discover its actual tool schemas before calling tools; an older installed clone may lack native pCalls. The modern server does not support direct STDIO. NetClaw provides scripts/pyats-stdio.py as a compatibility bridge to its stateless HTTP runtime; set PYATS_MCP_SCRIPT to that bridge (see docs/PYATS-HTTP-MIGRATION.md). Merely listing several shell commands does not execute a pyATS pCall.

Start every session with pyats_list_devices using {}. Use returned device names, group by role or site, and confirm the requested scope. Never invent device names or infer current operational state from a saved testbed.
