What is gogcli-mcp CLAUDE.md?

Project instructions for a monorepo, a repository containing several related packages, that provides separate Model Context Protocol servers for Google Workspace services through gogcli.

Use it when developing or maintaining the gogcli servers for Sheets, Docs, Drive, Slides, Classroom, Gmail, or the shared base package.

It helps an agent understand where each package lives, how shared authentication works, and how package versions and commands are organized.

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	$0.11628	$0.11628
Opus 5.5	$0.04651	$0.04651

Security

Grade A, and why

gogcli-mcp CLAUDE.md scanned grade A with 2 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 today.

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.

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.
