### Description (declared)

# 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…
