uv sync --all-extras --dev

If you are working on MCP Apps UI, install frontend dependencies and build the bundle:

cd src/mcp_google_workspace/apps/ui
npm ci
npm run build

Place credentials.json in one of:

• project root: ./credentials.json
• package credentials folder: ./src/credentials/credentials.json

On first run, the server launches a browser for OAuth consent and writes token.json.

Sheets, Docs, Tasks, People, Forms, and Slides are mounted by default and their scopes are always requested. If you are upgrading from an older checkout, delete token.json once so OAuth can re-consent the expanded scope set.

Google Keep OAuth scope can return invalid_scope in standard user OAuth flows. Keep integration is therefore disabled by default.

Enable Keep when your Google Workspace setup supports it:

$env:ENABLE_KEEP="true"

Google Chat OAuth scopes also commonly require Google Workspace accounts. Chat integration is therefore disabled by default.

Enable Chat when your Google Workspace setup supports it:

$env:ENABLE_CHAT="true"

Google Meet integration is also disabled by default. Enable it only after enabling the Meet API for the same OAuth client:

$env:ENABLE_MEET="true"

Gemini media integration is also disabled by default. Enable it with a Gemini Developer API key:

$env:ENABLE_GEMINI="true"
$env:GEMINI_API_KEY="your-api-key"

Capability-specific Gemini model defaults:

$env:GEMINI_IMAGE_GENERATE_MODEL="gemini-3.1-flash-image-preview"
$env:GEMINI_IMAGE_EDIT_MODEL="gemini-3.1-flash-image-preview"
$env:GEMINI_VIDEO_UNDERSTANDING_MODEL="gemini-3-flash-preview"
$env:GEMINI_AUDIO_UNDERSTANDING_MODEL="gemini-3-flash-preview"
$env:GEMINI_REASONING_MODEL="gemini-3.1-pro-preview"

Whenever you enable one of these optional integrations or otherwise change the scope set, delete token.json and re-authenticate to refresh granted scopes.

The MCP app-layer dashboard namespace is opt-in for controlled rollout.

Enable apps namespace:

$env:ENABLE_APPS_DASHBOARD="true"

uv run python -m mcp_google_workspace

This repository now includes a native uv-based MCP Bundle manifest and packaging assets.

Install on Claude Desktop:

1. Download the latest .mcpb from GitHub Releases.
2. In Claude Desktop, open the MCP bundle install flow.
3. Select the downloaded mcp-google-workspace-*.mcpb file.
4. Choose the credentials directory that contains credentials.json, or leave it empty to use the repo defaults.
5. Enable optional integrations only if your Google Workspace account and OAuth client support their scopes.
6. Finish the install and authenticate in the browser on first launch.

Gemini media tools are API-key-based rather than OAuth-based. If you enable Gemini in the bundle UI, also set the Gemini API key and optional model defaults there.

Build a local .mcpb archive only if you are developing or testing bundle changes:

uv run python scripts/build_mcpb.py

Note: Claude Desktop currently rejects extra server metadata keys such as package_manager, python_version, and working_dir, so this bundle keeps the uv server block to the manifest fields Claude accepts.

Bundle-specific documentation, runtime settings, and validation steps live in docs/MCPB.md.

$env:MCP_HOST="127.0.0.1"

• reply_email_prompt
• summarize_inbox_prompt
• summarize_keep_note_prompt
• extract_actions_from_keep_notes_prompt
• draft_chat_announcement_prompt
• summarize_chat_thread_prompt

These features depend on active MCP client support and may be silently unavailable in clients that do not implement the corresponding MCP capabilities.

When ENABLE_APPS_DASHBOARD=true, the apps_get_dashboard and apps_get_weekly_calendar_view tools carry an _meta.ui.resourceUri annotation pointing to ui://apps/dashboard-ui. MCP clients that support the Apps rendering protocol (e.g. Claude Desktop) will embed an interactive workspace dashboard UI alongside the tool response.

The UI is a TypeScript web component that communicates with the server via PostMessage. It renders:

• A weekly calendar view (all-day events + timed event columns)
• An inbox summary with email detail drill-down
• Scheduling action buttons (RSVP, reschedule, cancel)

Session-scoped state (current view, anchor date, selected calendars, inbox query) is stored server-side per session and managed through apps_get_state / apps_set_state / apps_patch_state.

Requires: MCP client with App/iframe rendering support.

Long-running tools emit incremental notifications/progress messages via ctx.report_progress(current, total, description). Clients that handle progress notifications can display progress bars or status messages during API-heavy operations.

Tools that emit progress:

Requires: MCP client that handles notifications/progress.

Several tools use MCP sampling (ctx.sample()) to generate LLM-powered summaries within the tool response, using the host client's configured model for inference.

Sampling-powered tools:

• gmail_summarize_email — summarizes an email body in up to 5 bullets
• keep_summarize_note — summarizes a Keep note
• chat_summarize_space_messages — summarizes recent messages in a Chat space

Requires: MCP client with sampling/createMessage support (e.g. Claude Desktop). Without sampling support these tools will fail or return an empty summary.

All request-schema-based tools now apply the same input normalization layer:

• Accepts camelCase and snake_case parameter keys for object payloads.
• Accepts full request payload as JSON string (must decode to an object).
• For list/dict fields, accepts JSON-string values; list fields also accept comma-separated strings.
• find_common_free_slots and apps_find_meeting_slots accept meeting_duration as alias for slot_duration_minutes.

Recommendation: send a normal JSON object with native arrays/objects whenever possible.

Google Keep API v1 currently exposes create, get, list, and delete for notes, plus permission batch create/delete. It does not expose a direct update/patch endpoint, archive/unarchive endpoints, or dedicated label endpoints in v1. The MCP server returns explicit unsupported responses for those operations.
