"""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.
