### Description (declared)

# search-excel-mcp

Local MCP server that lets any MCP client (Claude Code, Cursor, Claude Desktop, Cline, …) query complex Excel files (heavy merged cells, large size, multi-language text including CJK) via SQL and substring search — **no API keys, no embeddings, no GPU**.

Built with [FastMCP](https://github.com/jlowin/fastmcp) + [DuckDB](https://duckdb.org) + [openpyxl](https://openpyxl.readthedocs.io) + [pyarrow](https://arrow.apache.org/).

## Why this exists

Documentation-style Excel files (external design docs, report specs, requirements sheets) typically have thousands of merged cells per sheet, 20–100 MB per file, and multi-language text where most FTS tokenizers fail.

Standard RAG (embeddings + vector store) needs an LLM or embedding model that you can't always run locally. Your MCP client is the reasoning layer; this server just gives it accurate structured access to cells via DuckDB.

## Install

```bash
pip install search-excel-mcp
# or run without install:
uvx search-excel-mcp
```

## Configure your MCP client

Add to the client's MCP config file. Common locations:

| Client | Config path |
|---|---|
| Claude Code | `~/.claude/mcp.json` (global) or `<project>/.mcp.json` (project-local) |
| Cursor | `~/.cursor/mcp.json` (global) or `<project>/.cursor/mcp.json` (project-local) |
| Claude Desktop (macOS) | `~/Library/Application Support/Claude/claude_desktop_config.json` |
| Cline / other | see your client's docs |

Config entry (same JSON shape for all):

```json
{
  "mcpServers": {
    "search-excel": {
      "command": "uvx",
      "args": ["search-excel-mcp"],
      "env": {
        "SEARCH_EXCEL_DATA_DIR": "/absolute/path/to/your/excel/folder"
      }
    }
  }
}
```

Only `SEARCH_EXCEL_DATA_DIR` is required. The DuckDB cache is placed under your OS-standard app data folder (e.g. `~/Library/Application Support/search-excel-mcp/data.duckdb` on macOS) — override with `SEARCH_EXCEL_DB` if you want it elsewhere.

Restart your MCP client → the `se…
