Google Docs, Sheets, and Slides MCP sunucusu

Google MCP Server

An MCP (Model Context Protocol) server for reading Google Docs, Sheets, and Slides, and the comments and suggested edits on them.

Features

Read-only access to Google Docs, Sheets, Slides, and Drive comments via MCP tools. Two upload tools exist only if you turn on write mode.

Google Docs Tools

• get_document_metadata - Get document metadata (title, word count, element counts)
• get_document_content - Get structured content (headings, paragraphs, images, tables)
• get_document_text - Get all text as a single plain text string
• get_document_paragraphs - Get text organized by paragraphs
• get_document_suggestions - Get text split into original, inserted, and deleted by suggested edits

Google Drive Tools

• get_file_comments - List a file's comments with quoted text, resolved state, and replies
• upload_file - Upload a local file, optionally converting it to a Doc, Sheet, or Slides file (write mode only)
• update_file - Replace a Drive file's content, keeping its ID (write mode only)

Write mode is off by default. Start the server with --enable-write (or MCP_GOOGLE_ENABLE_WRITE=true) to register the two upload tools; they read local files only from --upload-root. See Google Drive tools.

Google Sheets Tools

• get_spreadsheet_metadata - Get spreadsheet metadata (title, sheet count, locale, time zone)
• list_sheets - List all sheets with their properties
• get_sheet_values - Get cell values from a specific range
• get_sheet_data - Get all data from a specific sheet
• get_multiple_ranges - Batch get values from multiple ranges

Google Slides Tools

• get_presentation - Get presentation metadata (title, slide count, locale, revision ID)
• list_slides - List all slides with titles and element counts
• get_slide - Get slide content and element details by index or object ID
• get_slide_notes - Get speaker notes by slide index or object ID
• get_presentation_content - Get all slides' text and images in one call (ideal for AI)

Architecture

This server is built on omniskill, making its Google Docs, Sheets, and Slides skills composable building blocks that can be reused in multi-service MCP servers.

Composable Skills

The skills in this repository can be imported and combined with other skills:

import (
    "github.com/plexusone/mcp-google/skills/docs"
    "github.com/plexusone/mcp-google/skills/sheets"
    "github.com/plexusone/mcp-google/skills/slides"
    runtime "github.com/plexusone/omniskill/mcp/server"
)

// Create runtime
rt := runtime.New(&mcp.Implementation{
    Name:    "work-mcp-server",
    Version: "v1.0.0",
}, nil)

// Add Google skills
docsSkill := docs.New(googleHTTPClient)
docsSkill.Init(ctx)
rt.RegisterSkill(docsSkill)

sheetsSkill := sheets.New(googleHTTPClient)
sheetsSkill.Init(ctx)
rt.RegisterSkill(sheetsSkill)

slidesSkill := slides.New(googleHTTPClient)
slidesSkill.Init(ctx)
rt.RegisterSkill(slidesSkill)

// Add other skills (Slack, Jira, GitHub, etc.)
rt.RegisterSkill(slackSkill)
rt.RegisterSkill(jiraSkill)

// Run server
rt.ServeStdio(ctx)

This enables building unified MCP servers that combine multiple services while keeping each service's implementation modular and maintainable.

Requirements

• Go 1.26+
• Google Cloud service account with Docs, Sheets, and Slides API access

Installation

go install github.com/plexusone/mcp-google/cmd/mcp-google@latest

Or build from source:

git clone https://github.com/plexusone/mcp-google.git
cd mcp-google
go build ./cmd/mcp-google

Setup

1. Create a Google Cloud Service Account

1. Go to the Google Cloud Console
2. Create a new project or select an existing one
3. Enable the Google Docs API, Google Sheets API, and Google Slides API
4. Create a service account with no special roles
5. Download the JSON credentials file

2. Share Documents with the Service Account

Share any documents, spreadsheets, or presentations you want to access with the service account's email address (found in the credentials JSON as client_email).

Usage

Option 1: Google Service Account Credentials

Use a standard Google Cloud service account JSON file:

mcp-google --credentials /path/to/service-account.json

Or using an environment variable:

export GOOGLE_CREDENTIALS_FILE=/path/to/service-account.json
mcp-google

Option 2: goauth CredentialsSet

Use a goauth CredentialsSet file, which can store multiple credentials:

mcp-google --goauth-credentials-file /path/to/credentials.json --goauth-credentials-account myaccount

Or using environment variables:

export GOAUTH_CREDENTIALS_FILE=/path/to/credentials.json
export GOAUTH_CREDENTIALS_ACCOUNT=myaccount
mcp-google

The CredentialsSet entry should be of type gcpsa with appropriate scopes:

{
  "credentials": {
    "myaccount": {
      "type": "gcpsa",
      "gcpsa": {
        "gcpCredentials": {
          "type": "service_account",
          "project_id": "...",
          "private_key_id": "...",
          "private_key": "...",
          "client_email": "...",
          "client_id": "..."
        },
        "scopes": [
          "https://www.googleapis.com/auth/documents.readonly",
          "https://www.googleapis.com/auth/spreadsheets.readonly",
          "https://www.googleapis.com/auth/presentations.readonly",
          "https://www.googleapis.com/auth/drive.readonly"
        ]
      }
    }
  }
}

Option 3: Vault-Backed Credentials

Use omnitoken with omnivault-desktop for secure credential storage in password managers.

Supported vault providers:

Provider	URI Pattern	Requirements
1Password	op://vault	OP_SERVICE_ACCOUNT_TOKEN env var
Bitwarden	bw://org-id	BW_ACCESS_TOKEN and BW_ORGANIZATION_ID env vars
File	file:///path	None
Env	env://PREFIX_	None

1Password Example

export OP_SERVICE_ACCOUNT_TOKEN="ops_..."
mcp-google --vault op://MyVault --credentials-name google

Bitwarden Example

export BW_ACCESS_TOKEN="..."
export BW_ORGANIZATION_ID="..."
mcp-google --vault bw://org-id --credentials-name google

File Vault Example

mcp-google --vault file:///path/to/secrets --credentials-name google

CLI Tool Commands

The CLI exposes one subcommand per MCP tool, plus serve and version.

mcp-google --help
mcp-google get-document-metadata <document-id-or-url> --credentials /path/to/service-account.json
mcp-google get-document-content <document-id-or-url> --include-metadata --include-images --include-tables -o pretty
mcp-google get-spreadsheet-metadata <spreadsheet-id-or-url> --credentials /path/to/service-account.json
mcp-google get-sheet-data <spreadsheet-id-or-url> --sheet-name "Sheet1" -o pretty
mcp-google get-presentation <presentation-id> --credentials /path/to/service-account.json

Use mcp-google <command> --help for command-specific flags. See docs/cli.md for the full CLI reference.

Claude Desktop Configuration

Add to your Claude Desktop configuration (claude_desktop_config.json):

With Google Service Account

{
  "mcpServers": {
    "google": {
      "command": "/path/to/mcp-google",
      "env": {
        "GOOGLE_CREDENTIALS_FILE": "/path/to/service-account.json"
      }
    }
  }
}

With goauth CredentialsSet

{
  "mcpServers": {
    "google": {
      "command": "/path/to/mcp-google",
      "env": {
        "GOAUTH_CREDENTIALS_FILE": "/path/to/credentials.json",
        "GOAUTH_CREDENTIALS_ACCOUNT": "myaccount"
      }
    }
  }
}

With 1Password

{
  "mcpServers": {
    "google": {
      "command": "/path/to/mcp-google",
      "env": {
        "OP_SERVICE_ACCOUNT_TOKEN": "ops_...",
        "OMNITOKEN_VAULT_URI": "op://MyVault",
        "OMNITOKEN_CREDENTIALS_NAME": "google"
      }
    }
  }
}

See docs/configuration/claude-desktop.md for more options including Bitwarden.

HTTP Transport (ID-JAG Authorization)

By default mcp-google serves over stdio. It can also serve streamable HTTP as a pure OAuth resource server, verifying bearer tokens issued by an external authorization server (enterprise IdP / ID-JAG delegation-chain tokens):

mcp-google serve \
  --http :8080 \
  --idjag-issuer https://idp.example.com \
  --idjag-audience https://mcp-google.example.com

Verified identity (subject, RFC 8693 act chain, scope) is audit-logged on every tool call, and calls are gated by scope (docs:read, sheets:read, slides:read, drive:read, and drive:write in write mode) when the token carries one. Each tool maps to exactly one required scope through an explicit per-tool table; when a scope claim is present, a tool without a mapping is denied. See docs/configuration/http-transport.md for the full flag/env reference.
