Google Sheets MCP Server

A Model Context Protocol (MCP) server providing full Google Sheets functionality. Read, write, format cells, create charts, use formulas, and manage spreadsheets directly from Claude, Cursor, or any MCP-compatible client.

Why I Built This

I created this MCP server for my college assignments, where I frequently work with data in Google Sheets — mostly financial sheets. Tasks like creating charts, writing formulas, formatting tables, and organizing data were repetitive and time-consuming. With this tool, I can automate all of that and focus on what actually matters — logical thinking and analysis — instead of doing the same manual work over and over again. :)

MCP Client Configuration

Claude Desktop

Add to your Claude Desktop config file:

macOS: `~/Library/Application Support/Claude/claude_desktop_config.json`
Windows: `%APPDATA%\Claude\claude_desktop_config.json`

json

{
  "mcpServers": {
    "google-sheets": {
      "command": "uv",
      "args": [
        "--directory",
        "/path/to/spreadsheet-mcp",
        "run",
        "spreadsheet-mcp"
      ]
    }
  }
}

Claude Code (CLI)

Add to your project's `.mcp.json` file:

json

{
  "mcpServers": {
    "google-sheets": {
      "command": "uv",
      "args": [
        "--directory",
        "/path/to/spreadsheet-mcp",
        "run",
        "spreadsheet-mcp"
      ]
    }
  }
}

Cursor

Add to Cursor's MCP settings (Settings → MCP → Add Server):

json

{
  "mcpServers": {
    "google-sheets": {
      "command": "uv",
      "args": [
        "--directory",
        "/path/to/spreadsheet-mcp",
        "run",
        "spreadsheet-mcp"
      ]
    }
  }
}

Or add to `~/.cursor/mcp.json`:

json

{
  "mcpServers": {
    "google-sheets": {
      "command": "uv",
      "args": [
        "--directory",
        "/path/to/spreadsheet-mcp",
        "run",
        "spreadsheet-mcp"
      ]
    }
  }
}

Gemini CLI

For Gemini CLI with MCP support, add to your MCP configuration:

json

{
  "mcpServers": {
    "google-sheets": {
      "command": "uv",
      "args": [
        "--directory",
        "/path/to/spreadsheet-mcp",
        "run",
        "spreadsheet-mcp"
      ]
    }
  }
}

Using with npx (Alternative)

If you prefer npx over uv:

json

{
  "mcpServers": {
    "google-sheets": {
      "command": "npx",
      "args": [
        "-y",
        "uv",
        "--directory",
        "/path/to/spreadsheet-mcp",
        "run",
        "spreadsheet-mcp"
      ]
    }
  }
}

Note: Replace `/path/to/spreadsheet-mcp` with the actual path where you cloned this repository.
