+"""Regression tests for MCP server availability in cron jobs.
+
+Background
+==========
+``cron/scheduler.py:run_job()`` constructs ``AIAgent(...)`` directly without
+calling ``discover_mcp_tools()`` — the initialization that CLI and gateway
+paths do at startup. Cron jobs therefore never saw any MCP tools from
+``mcp_servers`` in config.yaml. See #4219.
+
+The fix inserts ``discover_mcp_tools()`` before the ``AIAgent(...)`` call,
+wrapped in try/except so a broken MCP server can't kill an otherwise
+working cron job. ``discover_mcp_tools`` is idempotent — subsequent ticks
+short-circuit on already-connected servers.
