v0.5.2

Deprecated

• flac-mcp is deprecated and frozen in favor of itasca-mcp, a single
  multi-engine server covering FLAC, PFC, 3DEC, MPoint, and MassFlow. The
  server instructions now lead with a migration notice, so an agent
  connecting to this server is told to switch. No further releases are planned.
  Migrate your MCP client config from uvx flac-mcp to uvx itasca-mcp
  (select FLAC3D docs via the software parameter). This release stays
  functional against itasca-mcp-bridge >= 0.4.0.

v0.5.1

Fixed

• Replaced leftover PFC examples in MCP tool descriptions with FLAC
  equivalents (descriptions only — no behavior change). Affects
  flac_browse_python_api / flac_query_python_api (API-path and keyword
  examples), the shared command/API search-query field descriptions,
  flac_browse_commands, and flac_execute_code: e.g.
  itasca.ball / itasca.wall.facet → itasca.zone / itasca.interface.node,
  ball create / contact force → zone create / gridpoint velocity. All
  new examples verified against the live FLAC3D 9.0 Python API.

v0.5.0

Added

• --bridge-port CLI argument to override the bridge connection port —
  shorthand for --bridge-url ws://localhost:PORT. When a full
  --bridge-url / FLAC_MCP_BRIDGE_URL is also supplied, only its port is
  overridden.

Changed

• flac_execute_task now submits over the bridge's execute_task message
  (renamed from pfc_task so the shared bridge protocol is product-neutral;
  the bridge keeps pfc_task as a deprecated alias). Requires
  itasca-mcp-bridge >= 0.1.5 — older bridges silently ignore the message
  and submission times out. If that happens, confirm the bridge version with
  flac_execute_code (import itasca_mcp_bridge; print(itasca_mcp_bridge.__version__)) and upgrade by re-running addon.py.
• Slimmed flac_check_task_status pagination to total_lines + line_range,
  replacing the heavier pagination object. Output windows are still selected
  with skip_newest / limit / filter_text.
• Bumped itasca-mcp-bridge to 0.1.5 (submodule pin). Picks up the PySide6
  Qt task-pump fix so the bridge starts on PFC 9.7+ (Python 3.10 / Qt6) and
  the execute_task protocol rename.

v0.1.1

Fixed

• Bumped itasca-mcp-bridge to 0.1.3 (submodule pin 25668d7), picking up
  the command-log and task-log abspath-vs-CWD fixes. itasca.command() output
  and flac_check_task_status no longer come back empty when the engine's
  working directory diverges from Python's (headless consoles, or after a task
  os.chdir()): the task log and tasks.json are now read from a bridge root
  frozen at startup rather than the live working directory.

Changed

• Task elapsed_time is now rounded to 2 decimals in flac_check_task_status
  and flac_list_tasks (e.g. 0.01 instead of 0.010000944137573242). The
  field stays numeric; the bridge still reports full precision, with rounding
  applied at the MCP presentation layer alongside start_time / end_time.

Documentation

• Added a README header image (#51).

v0.1.0

Initial release of flac-mcp. Scaffolded from pfc-mcp 0.3.15: the MCP
server was renamed (flac_* tools, src/flac_mcp package) and retargeted
to the ITASCA FLAC product family (FLAC2D/FLAC3D); the in-product bridge
runtime was extracted to the standalone itasca-mcp-bridge package. The
bundled command/API/reference knowledge base is inherited from pfc-mcp
and currently covers ITASCA command documentation.
