gworkspace-mcp: MCP Tools + Python API

Interface Decision Guide

Situation	Use
Claude performing an action in an interactive session	MCP tools (call directly)
Python script automating Google Workspace	Python API
Need data not covered by MCP tools	Python API with googleapiclient
Bulk/batch operations in code	Python API
Claude reading data then passing to Python logic	Both — MCP to fetch, Python to process
Embedding the MCP server in your own app	GoogleWorkspaceServer / create_server()

---

Authentication (Shared by Both Interfaces)

Run once per project directory:

gworkspace-mcp setup

Tokens are stored at ./.gworkspace-mcp/tokens.json (project-local).

Get Credentials for Python API

from gworkspace_mcp.auth import OAuthManager, TokenStatus

manager = OAuthManager()

# Check status before use
status, stored = manager.get_status()
# status is one of: TokenStatus.VALID, EXPIRED, MISSING, INVALID

# Get google.oauth2.credentials.Credentials object
credentials = manager.get_credentials()  # None if not authenticated

# Auto-refresh if expired
token = await manager.refresh_if_needed()

Scopes Granted by Setup

from gworkspace_mcp.auth import GOOGLE_WORKSPACE_SCOPES
# Includes: calendar, gmail.modify, drive, documents, tasks, spreadsheets, presentations

---

Python API Usage

Use the Python API when your code (not Claude) needs to drive Google Workspace — automation scripts, data pipelines, custom integrations.

Setup

from gworkspace_mcp.auth import OAuthManager
from googleapiclient.discovery import build

manager = OAuthManager()
credentials = manager.get_credentials()
# credentials is google.oauth2.credentials.Credentials
# Ready to pass to any googleapiclient service

Gmail

service = build('gmail', 'v1', credentials=credentials)

# Search messages
results = service.users().messages().list(
    userId='me',
    q='from:[e-mail] is:unread'
).execute()
messages = results.get('messages', [])

# Get full message
msg = service.users().messages().get(
    userId='me',
    id=messages[0]['id'],
    format='full'
).execute()

# Send email
import base64
from email.mime.text import MIMEText

message = MIMEText('Hello World')
message['to'] = '[e-mail]'
message['subject'] = 'Test'
raw = base64.urlsafe_b64encode(message.as_bytes()).decode()
service.users().messages().send(
    userId='me',
    body={'raw': raw}
).execute()

# Batch modify labels
service.users().messages().batchModify(
    userId='me',
    body={
        'ids': ['msg1', 'msg2'],
        'addLabelIds': ['STARRED'],
        'removeLabelIds': ['UNREAD']
    }
).execute()

Calendar

service = build('calendar', 'v3', credentials=credentials)

# List upcoming events
from datetime import datetime, timezone
now = datetime.now(timezone.utc).isoformat()

events = service.events().list(
    calendarId='primary',
    timeMin=now,
    maxResults=10,
    singleEvents=True,
    orderBy='startTime'
).execute()

# Create event
event = service.events().insert(
    calendarId='primary',
    body={
        'summary': 'Team Meeting',
        'start': {'dateTime': '2024-03-15T10:00:00-07:00'},
        'end': {'dateTime': '2024-03-15T11:00:00-07:00'},
        'attendees': [{'email': '[e-mail]'}],
    }
).execute()

# Free/busy query

    media_body=media,
    fields='id'
).execute()

# Download file
from googleapiclient.http import MediaIoBaseDownload
import io

request = service.files().get_media(fileId='file_id')
fh = io.BytesIO()
downloader = MediaIoBaseDownload(fh, request)
done = False
while not done:
    _, done = downloader.next_chunk()

# Export Google Doc as PDF
request = service.files().export_media(
    fileId='doc_id',
    mimeType='application/pdf'
)

Sheets

service = build('sheets', 'v4', credentials=credentials)
ss = service.spreadsheets()

# Read values
result = ss.values().get(
    spreadsheetId='spreadsheet_id',
    range='Sheet1!A1:D10'
).execute()
rows = result.get('values', [])

# Write values
ss.values().update(
    spreadsheetId='spreadsheet_id',
    range='Sheet1!A1',
    valueInputOption='USER_ENTERED',
    body={'values': [['Name', 'Score'], ['Alice', 95], ['Bob', 87]]}

    spreadsheetId='spreadsheet_id',
    range='Sheet1!A:A',
    valueInputOption='USER_ENTERED',
    body={'values': [['New Row', 'Data']]}
).execute()

# Batch update (formatting, merges, etc.)
ss.batchUpdate(
    spreadsheetId='spreadsheet_id',
    body={'requests': [
        {'repeatCell': {
            'range': {'sheetId': 0, 'startRowIndex': 0, 'endRowIndex': 1},
            'cell': {'userEnteredFormat': {'textFormat': {'bold': True}}},
            'fields': 'userEnteredFormat.textFormat.bold'
        }}
    ]}
).execute()

Docs

service = build('docs', 'v1', credentials=credentials)

# Read document
doc = service.documents().get(documentId='doc_id').execute()
content = doc.get('body', {}).get('content', [])

# Create document
doc = service.documents().create(
    body={'title': 'New Document'}
).execute()

# Batch update (insert text, format, etc.)
service.documents().batchUpdate(
    documentId='doc_id',
    body={'requests': [
        {'insertText': {
            'location': {'index': 1},
            'text': 'Hello World\n'
        }},
        {'updateTextStyle': {
            'range': {'startIndex': 1, 'endIndex': 6},
            'textStyle': {'bold': True},
            'fields': 'bold'
        }}

    presentationId='prs_id'
).execute()
slides = prs.get('slides', [])

# Create presentation
prs = service.presentations().create(
    body={'title': 'Q1 Review'}

Embedding the MCP Server (Advanced)

Run the MCP server programmatically inside your own application:

import asyncio
from gworkspace_mcp.server import GoogleWorkspaceServer, create_server

# Option 1: Quick create
server = create_server()
asyncio.run(server.run())

# Option 2: Full control
server = GoogleWorkspaceServer()
# server.storage  → TokenStorage instance
# server.manager  → OAuthManager instance
# server.server   → underlying mcp.server.Server
asyncio.run(server.run())

---

Combined Patterns

Pattern 1: Claude discovers, Python processes

# In your code: get credentials
from gworkspace_mcp.auth import OAuthManager
creds = OAuthManager().get_credentials()

# Claude (via MCP): search_gmail_messages query="invoice from:[e-mail]"
# Claude returns message IDs → pass to Python for bulk processing

from googleapiclient.discovery import build
gmail = build('gmail', 'v1', credentials=creds)
for msg_id in message_ids_from_claude:
    msg = gmail.users().messages().get(userId='me', id=msg_id).execute()
    # custom processing...

Pattern 2: Python automation + Claude narration

# Python creates the spreadsheet and populates data
sheets = build('sheets', 'v4', credentials=creds)
ss = sheets.spreadsheets().create(body={'title': 'Report'}).execute()
sheets.spreadsheets().values().update(
    spreadsheetId=ss['spreadsheetId'],
    range='A1', valueInputOption='USER_ENTERED',
    body={'values': data_rows}
).execute()

# Then Claude (via MCP) formats it:
# format_cells spreadsheetId=... range="A1:Z1" bold=true
# create_chart spreadsheetId=... chart_type="bar" ...

Pattern 3: Token reuse — avoid double authentication

from gworkspace_mcp.auth import OAuthManager, TokenStorage

# Both MCP server and your code share the same token storage
storage = TokenStorage()  # reads .gworkspace-mcp/tokens.json
manager = OAuthManager(storage=storage)
creds = manager.get_credentials()
# No re-authentication needed — same tokens the MCP server uses

---

Error Handling

from gworkspace_mcp.auth import OAuthManager, TokenStatus
from googleapiclient.errors import HttpError

manager = OAuthManager()
status, stored = manager.get_status()

if status == TokenStatus.MISSING:
    raise RuntimeError("Run 'gworkspace-mcp setup' first")
elif status == TokenStatus.EXPIRED:
    token = await manager.refresh_if_needed()
elif status == TokenStatus.INVALID:
    raise RuntimeError("Token corrupted — run 'gworkspace-mcp setup' to re-authenticate")

try:
    result = service.users().messages().list(userId='me', q='...').execute()
except HttpError as e:
    if e.resp.status == 401:
        # Token expired mid-session — refresh and retry
        await manager.refresh_if_needed()
    elif e.resp.status == 429:
        # Rate limited — back off
        import time; time.sleep(2)
    else:
        raise
