What is gogcli-mcp-sheets?

A set of tools for reading, editing, formatting, and managing Google Sheets, including tabs, cells, ranges, exports, and layout settings.

It helps add or rename tabs, read and format cells, freeze rows or columns, merge cells, resize columns, and export sheets as CSV, TSV, XLSX, or PDF.

It provides one place to handle spreadsheet data and structure without switching between separate spreadsheet operations.

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	$0.00065	$0.01515
Opus 5	$0.00032	$0.00758
Sonnet 5	$0.00013	$0.00303
Haiku 4.5	$0.00006	$0.00152

Security

Grade A, and why

gogcli-mcp-sheets 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 8d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (src/index.ts, src/tools/sheets-extra.ts, tests/tools/sheets-extra.test.ts, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.
