# Excel MCP Excel MCP is a Python MCP server and companion CLI for safe, token-efficient work with local Excel `.xlsx` workbooks. It is designed for financial and operations workflows such as bookkeeping, accounting, marketing operations, SEO exports, research tables, reconciliations, and financial report review. Core behavior: - Describe workbook structure before reading bulk data. - Query detected worksheet regions with DuckDB SQL. - Inspect exact ranges only when needed. - Stage writes as dry-runs. - Diff before commit. - Save edits to a new workbook by default. - Keep an audit trail of reads, queries, staged writes, diffs, commits, and failures. Google Sheets and Apple Numbers are not supported in this phase. ## Install ### Recommended: `uvx` If `uv` is installed, run the MCP server without creating a virtual environment: ```bash uvx excel-ops-mcp ``` Run the CLI without a persistent install: ```bash uvx --from excel-ops-mcp excel-ops sheets workbook.xlsx ``` ### One-command install (all agents) Bootstraps `uv` if needed, then opens a picker to install `excel-ops-mcp` into Claude Desktop, Claude Code, Codex, Gemini CLI, Cursor, and/or Windsurf: ```bash curl -LsSf https://raw.githubusercontent.com/dasein108/excel-ops-mcp/main/install.sh | sh ``` Windows (PowerShell): ```powershell powershell -ExecutionPolicy ByPass -c "irm https://raw.githubusercontent.com/dasein108/excel-ops-mcp/main/install.ps1 | iex" ``` The picker first asks Install or Uninstall, then shows a `[ ]`/`[X]` checkbox list (everything unchecked to start). Toggle agents by number and press Enter. Each agent is labelled `installed` / `detected` / `not found`. Non-interactive: `... | sh -s -- --agents cursor,claude-code` to install, or `--uninstall cursor,claude-code` to remove. Preview with `--dry-run`; see status with `--list`. **Updating:** re-run the same command anytime — the bootstrap refreshes the uvx cache so both the installer and the server your agents launch move to the…
