### Description (declared)

# grp-mcp

MCP server that exposes **Acumatica ERP** as tools for AI agents. Multi-instance,
OAuth2 — point it at any Acumatica site with a base URL + credentials.

It reaches Acumatica through **five client planes** (four for driving, one
diagnostic-only), so an agent can read and write almost anything:

- **Contract-based REST** — CRUD entities, bulk-load from Excel/CSV, invoke
  actions, run reports, attach files, manage customization projects.
- **DAC-based OData** — read tables/DACs that aren't on the endpoint, plus
  mandatory-field metadata (`run_dac_odata`, `get_dac_metadata`).
- **Screen-based SOAP engine** — *drive screens the REST API can't*: context /
  master-detail / wizard screens (segment values, Enable Features, the financial
  calendar…). Discover (`list_screens`, `screen_get_schema`), read (`screen_get`),
  and write (`screen_submit`, with dry-run + per-field errors + dialog
  auto-answer) any screen by replaying its UI commands — no browser, no zeep.
  Higher-level writers (`screen_insert_rows` for master-detail/bulk grids,
  `screen_record` for idempotent create-or-edit) and ready-made setup recipes
  (`create_financial_calendar`, `create_ledger`, `chart_of_accounts`,
  `enable_features`, `manage_financial_periods`) sit on top.
- **Modern UI-screen plane** — the JSON protocol the real browser UI uses
  (`/t/<Tenant>/ui/screen/<ScreenID>`), reusing the SAME login session as the
  classic plane (no extra auth, no browser). `ui_get_structure` reads a screen's
  full descriptor — views, fields, **enum allowed-values**, action inventory,
  grid keys — and `ui_screen_action` sets fields + fires actions (incl.
  dialog-confirm). This reaches what classic SOAP can't: actions whose classic
  tag is a silent no-op (e.g. GL201000 Generate Calendar), enum value discovery,
  live workflow-aware field/action state, and **full grid CRUD** — read, insert,
  update, and delete an *existing* grid row (the classic engine can only append
  rows; editing one in pla…
