What is google-drive-mcp-server CLAUDE.md?

Project instructions for a TypeScript server that connects an AI assistant to Google Drive and other Google Workspace APIs through the Model Context Protocol. They describe its tools, build commands, tests, and handling of personal versus business Workspace accounts.

Use them when developing, testing, or extending the Google Drive MCP server. They cover Node.js and pnpm commands, Zod input schemas, Google API calls, and tool registration.

They give contributors a shared set of technical rules for building and running the server. This reduces inconsistent API calls, validation, registration, and account-capability handling.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.03568	$0.03568
Opus 5.5	$0.01427	$0.01427
Sonnet 5.5	$0.00714	$0.00714
Haiku 4.5	$0.00357	$0.00357

Security

Grade A, and why

google-drive-mcp-server CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Google Drive MCP Server

Tech Stack

Node.js 18+, pnpm, TypeScript (strict, ESM)
@modelcontextprotocol/sdk — MCP protocol
googleapis — Google Drive API v3, Drive Activity API v2, Drive Labels API v2, Sheets API v4, Slides API v1, Docs API v1
zod — input validation
dotenv — env loading
vitest — testing

Build & Run

pnpm install
pnpm run build
pnpm start              # or: node dist/index.js
pnpm run dev            # watch mode
pnpm run test           # unit tests
pnpm run smoke          # live API smoke test

Architecture

Claude → MCP (stdio) → index.ts → tools/* → googleapis → Google Drive API
                              ↑
                    capabilities.ts (personal vs GWS detection)

Tool Pattern

Each tool file exports: schema (Zod) + handler (async function). Registration in index.ts: server.tool(name, description, schema.shape, wrapToolHandler(handler)).

Every schema field must have .describe(). Use z.coerce.number() for numbers. Always pass supportsAllDrives: true to Drive API calls.

GWS Awareness

capabilities.ts detects account type on startup via about.get() + domain check
GWS-only tools call requireGWS(caps, "Feature Name") which throws GWSFeatureError for personal accounts
Write tools call assertWriteAllowed() which checks GOOGLE_DRIVE_ALLOW_WRITE=true

Auth Methods

OAuth2: GOOGLE_CLIENT_ID + GOOGLE_CLIENT_SECRET + GOOGLE_REFRESH_TOKEN
Service Account: GOOGLE_SERVICE_ACCOUNT_KEY_PATH + optional GOOGLE_IMPERSONATE_USER
ADC: gcloud auth application-default login --client-id-file=client_secret.json --scopes=... (auto-detected)

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
