ida-pro-mcp: AttributeError: ida_kernwin has no attribute parse_tagged_line_sections

  The root cause is an IDA version mismatch: parse_tagged_line_sections was added in IDA Pro 9.1, so the plugin's disassemble_function tool fails on IDA 9.0. A contributor identified this and linked the Hex-Rays 9.1 release notes; the maintainer said it was "very likely a real issue" and kept the ticket open to investigate. The issue is now closed (COMPLETED).

  To fix it, upgrade to IDA Pro 9.1 or newer, where the API exists. The traceback shows the failure happens in mcp-plugin.py line 931 inside disassemble_function, so until you upgrade, that tool cannot be used. General advice: while on IDA 9.0, avoid calling disassemble_function from the plugin. A comment also suggested that unexpected errors can sometimes be resolved by retrying, but nobody in the thread reported actually retrying or the result, and the maintainer's reply suggests the failure is real rather than transient.

  What @XUCharles tried on GitHub (Didn't work)

  Reproduced the exact same AttributeError on IDA Pro 9.0.241217 with Python 3.11.0, confirming the failure is not specific to the original reporter's installation.

  What @giejck18470 tried on GitHub (Outcome unclear)

  A comment suggested that unexpected errors can be solved by retrying, but no one in the thread reported trying this, so the suggestion's effectiveness is unknown.
