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	$0.01137	$0.01137
Opus 5.5	$0.00455	$0.00455
Sonnet 5.5	$0.00227	$0.00227
Haiku 4.5	$0.00114	$0.00114

Security

Grade A, and why

google-workspace-mcp 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.

Project Overview

This is a minimal npm distribution wrapper for the upstream gemini-cli-extensions/workspace Google Workspace MCP server.

Purpose: Enable easy installation via npx @presto-ai/google-workspace-mcp for employees to access Google Workspace services (Gmail, Calendar, Drive, Docs, Sheets, Chat) from Claude Desktop/Code.

Philosophy: This project is a glorified shim and CI/CD pipeline. We do NOT maintain custom code - we simply package upstream for npm distribution.

What This Project Does

Syncs source from upstream - All code in src/ comes directly from gemini-cli-extensions/workspace
Customizes paths.ts only - Changes token storage to ~/.config/google-workspace-mcp/ instead of project root
Publishes to npm - Makes it installable via npx

What This Project Does NOT Do

No custom tests (upstream handles testing)
No custom linting infrastructure
No custom features or modifications
No divergence from upstream behavior

Essential Commands

npm install          # Install dependencies
npm run build        # Build TypeScript → dist/
npm link             # Test locally
google-workspace-mcp --auth  # Authenticate

The One Customization: paths.ts

We override src/utils/paths.ts to store tokens in a persistent user config directory:

What this file has done since we first saw it

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.
