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 | $0.00257 | $0.00257 |
| Opus 5 | $0.00129 | $0.00129 |
| Sonnet 5 | $0.00051 | $0.00051 |
| Haiku 4.5 | $0.00026 | $0.00026 |
Grade A, and why
google-workspace-mcp GEMINI.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 9d 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.
This is a copy
100% identical to workspace GEMINI.md — 22 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
This is a Gemini extension that provides tools for interacting with Google Workspace services like Google Docs.
Building and Running
- Install dependencies:
npm install - Build the project:
npm run build --prefix workspace-server
Development Conventions
This project uses TypeScript and the Model Context Protocol (MCP) SDK to create a Gemini extension. The main entry point is src/index.ts, which initializes the MCP server and registers the available tools.
The business logic for each service is separated into its own file in the src/services directory. For example, src/services/DocsService.ts contains the logic for interacting with the Google Docs API.
Authentication is handled by the src/auth/AuthManager.ts file, which uses the @google-cloud/local-auth library to obtain and refresh OAuth 2.0 credentials.
Adding New Tools
To add a new tool, you need to:
- Add a new method to the appropriate service file in
src/services. - In
src/index.ts, register the new tool with the MCP server by callingserver.registerTool(). You will need to provide a name for the tool, a description, and the input schema using thezodlibrary.
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.
