    "body": "Of the MCP servers in this batch, Excel MCP Server has the sharpest and most defensible thesis. Instead of parsing and rewriting .xlsx files directly the way openpyxl-based servers (and Anthropic's own xlsx skill) do — which can silently drop PivotTables, charts and macros and simply cannot execute Power Query, the Data Model or DAX — it automates the actual Excel application through Microsoft's official COM API. Excel itself opens, computes and saves the workbook, so formulas, PivotTables, charts, macros, the Data Model and formatting survive intact, and live operations (refresh Power Query, evaluate DAX, run VBA and Python =PY()) return real computed results. That is a real, correctly-argued technical distinction, not marketing gloss, and the docs make the trade-off explicit rather than hiding it. Maturity signals back it up: a v2.0.5 release, ~645 GitHub stars, an MIT license, a documented surface of 31 tools across ~325 operations, and first-class install paths for VS Code / Copilot / Claude and any MCP client. The honest limits: it is Windows-and-real-Excel-bound by design (the COM API requires a genuine Excel install), so it is not a cross-platform or headless-server play; and because this is a public-surface review, the breadth of those 325 operations is documented but not independently exercised here. Within its lane, this is a well-built, well-scoped, unusually candid tool.",

  "tier_rationale": "STEADY (80), medium-high confidence — one of the stronger public surfaces in this cohort. It earns the upper-STEADY band on a genuinely differentiated technical approach (real Excel COM engine vs. file-rewriting), clear maturity (v2.0.5, ~645 stars, MIT), thorough documentation, and refreshingly honest positioning that names its own trade-offs and its competitors' failure modes. Held short of VITAL because the review is a documentation read rather than an execution of all 325 operations, and because the architecture is deliberately Windows/Excel-bound, which caps its addressable surface.",
