praisonai-triage-agent[bot]andMervinPraison 817942a4ab fix: MCP splits multi-word command string when args supplied (fixes #3940)
Previously MCP("npx -y pkg", args=[...]) passed the whole string as the
executable, so the subprocess spawn silently failed and 0 tools were
discovered. Now the command string is split on whitespace regardless of
whether args are supplied, using the first token as the executable and
prepending the remaining tokens to any explicit args.

Also updates examples/python/mcp/filesystem-mcp.py to use the reliable
executable + args form.
