before you install - you'll need

XLSX_MCP_FILES

Environment variables documented in the project's README - it lists which are required and which have defaults.

Claude Code

claude mcp add ruriazz-xlsx-tools-mcp -- uvx xlsx-tools-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "ruriazz-xlsx-tools-mcp": {
      "command": "uvx",
      "args": [
        "xlsx-tools-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.
