MinaSaad1 b777adec55 feat: v2.0.0 - replace MCP server with direct pythonnet/.NET TOM interop 
Remove the MCP server binary dependency entirely. All 22 command groups now
connect directly to Power BI Desktop's Analysis Services engine via pythonnet
and bundled Microsoft.AnalysisServices DLLs (~20MB, in-process).

- Direct .NET TOM/ADOMD.NET interop for sub-second command execution
- 7 Claude Code skills (added Diagnostics and Partitions & Expressions)
- New commands: trace, transaction, calendar, expression, partition, advanced culture
- 91 tests passing, all skills updated, README/CHANGELOG rewritten

[2.0.0] - 2026-03-27

Breaking

  • Removed MCP server dependency entirely (no more powerbi-modeling-mcp binary)
  • Removed connect-fabric command (future work)
  • Removed per-object TMDL export (table export-tmdl, measure export-tmdl, etc.) -- use pbi database export-tmdl
  • Removed model refresh command
  • Removed security-role export-tmdl -- use pbi database export-tmdl

Added

  • Direct pythonnet/.NET TOM interop (in-process, sub-second commands)
  • Bundled Microsoft Analysis Services DLLs (~20MB, no external download needed)
  • 2 new Claude Code skills: Diagnostics and Partitions & Expressions (7 total)
  • New commands: trace start/stop/fetch/export, transaction begin/commit/rollback, calendar list/mark, expression list/get/create/delete, partition list/create/delete/refresh, advanced culture list/get
  • connections last command to show last-used connection
  • pbi connect now auto-installs skills (no separate pbi skills install needed)

Changed

  • pbi setup now verifies pythonnet + bundled DLLs (no longer downloads a binary)
  • Architecture: Click CLI -> tom_backend/adomd_backend -> pythonnet -> .NET TOM (in-process)
  • All 7 skills updated to reflect v2 commands and architecture
  • README rewritten for v2 architecture

Removed

  • MCP client/server architecture
  • Binary manager and auto-download from VS Code Marketplace
  • $PBI_MCP_BINARY environment variable
  • ~/.pbi-cli/bin/ binary directory

[1.0.6] - 2026-03-26

Fixed

  • Use server-assigned connection name for subsequent commands (fixes "connection not found" mismatch)

[1.0.5] - 2026-03-26

Fixed

  • Auto-reconnect to saved connection on each command (each invocation starts a fresh MCP server)

[1.0.4] - 2026-03-26

Fixed

  • Commands now auto-resolve last-used connection from store (no --connection flag needed)

[1.0.3] - 2026-03-26

Added

  • Support Microsoft Store version of Power BI Desktop for port auto-discovery

Fixed

  • UTF-16 LE encoding when reading Power BI port file
  • Updated all 5 skills, error messages, and docs to reflect new install flow

[1.0.2] - 2026-03-26

Fixed

[1.0.0] - 2026-03-26

Added

  • Interactive REPL mode (pbi repl) with persistent MCP connection, tab completion, command history
  • Error hierarchy (PbiCliError, McpToolError, BinaryNotFoundError, ConnectionRequiredError)
  • 22 command groups covering all Power BI MCP tool operations
  • Binary manager: download Power BI MCP binary from VS Code Marketplace
  • Connection management with named connections and persistence

  • Database import/export (TMDL and TMSL formats)
  • Security role management (row-level security)
  • Calculation groups, partitions, perspectives, hierarchies
  • Named expressions, calendar tables, diagnostic traces
