be-amsa-reporter-te

MCP server that automates a BE AMSA review end-to-end. Trigger it in chat with:

create a backend amsa report

Refactored, optimized and watchdog-guarded successor to be-amsa-manager-te. It keeps only the proven, active automation path, runs the whole multi-minute pipeline on a worker thread behind a hard timeout (so the chat can never hang), and stages all EFF/report I/O on local disk to avoid slow SMB round-trips.

What it does

1. Lists the sub-folders under \\Mucsdn31\ATV_Power_Pro\MOSFET_TE\Test_program_status_tracking\Copilot_BE_AMSA\effdata and asks which one to analyse.

2. Validates the chosen folder: exactly one .eff file ending in each of _S1R1, _S1R2, _S2R1, _S2R2 (no duplicates). If not, it returns an actionable message.

3. Stages the four EFFs locally and drives AMSA 5.1:

   • Launches it from a clean slate (kills any stale GageAnalysis.exe) and dismisses the Precondition failed popup with Yes.

   • File > New → Setup Dialog → adds the four EFF files with TestSetup = 1, 1, 2, 2.

   • Sets the option groups (Test ID by Name and Number, Device no further identification, Unit no rescaling + dB/log(A) linearisation, Override die coordinates).

   • Start → ticks the listed Test Nr to exclude → Continue → Continue → OK.

   • Reads the results grid, sorts by GrR, self-calibrates the row geometry, and for every test with GrR ≥ 10 % ensures both S (Scatter) and P (Probability) are marked; unmarks any below threshold. Marks are verified and re-tried until they converge.

   • Configuration > Setup information → sets each row's Description to its EFF file name (matched by Setup No / Rep No).

   • Results > Write HTML-Report → writes the report + a Graphs\ sub-folder of JPGs.

4. Copies the report + Graphs back to the share and builds a PowerPoint into Copilot_BE_AMSA\generatedppt\<folder>.pptx:

   • Slide 1: <folder> AMSA Review

   • Slide 2: Data Description (the four EFF file names)

   • Slide 3: GrR Summary (Gr&R > 25 % and 10 % ≤ Gr&R ≤ 25 %)

   • Slide 4: GrR Summary (all tests) — bar chart with 10 %/25 % red boundary lines

   • Slide 5+: one slide per test with GrR ≥ 10 %, scatter + probability JPG + assessment.

Why it will not hang

The create_backend_amsa_report tool only awaits the folder pick on the event loop; the entire blocking pipeline runs on a worker thread (anyio.to_thread.run_sync). A watchdog (BEAR_RUN_TIMEOUT, default 20 min) wraps the run — on timeout the worker is abandoned, AMSA is force-killed and a clear timeout result is returned. A progress heartbeat (BEAR_HEARTBEAT_SECONDS, default 10 s) reports the current phase so the run never looks stuck.

Restart the MCP server (Command Palette → MCP: List Servers → be-amsa-reporter-te → Restart) after any code/config edit — a running server keeps the old modules in memory.

Configuration

Everything is overridable via BEAR_* environment variables (no code changes needed). Common knobs: BEAR_MAIN_WINDOW_TITLE_RE, BEAR_UI_BACKEND, BEAR_EXCLUDE_TEST_NRS, BEAR_GRR_PLOT_THRESHOLD, BEAR_GRR_HIGH_THRESHOLD, BEAR_RUN_TIMEOUT, BEAR_HEARTBEAT_SECONDS, and the results-grid geometry / control IDs in config.py.

Modules

• config.py — all paths/selectors/tunables from BEAR_* env.

• folders.py — list + validate effdata folders.

• amsa_driver.py — pywinauto automation of AMSA 5.1 (active path only).

• html_report.py — parse the generated HTML for Test Nr / name / GrR / limits.

• ppt_report.py — build the review PowerPoint from the HTML + Graphs\ JPGs.

• server.py — FastMCP server exposing create_backend_amsa_report, worker thread + watchdog + heartbeat.
