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.

Security

Grade A, and why

gogcli-mcp 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 3d 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.

What it actually says

gogcli-mcp

MCP server wrapping gogcli — provides Claude with access to Google Sheets (and a scaffold for Gmail, Calendar, Drive, and more).

Requirements

  • gogcli installed and authenticated (gog --help works in your shell)
  • Node.js 18 or later

Setup

Option A — Claude Code (direct MCP)

Add to .mcp.json in your project:

{
  "mcpServers": {
    "gogcli": {
      "command": "node",
      "args": ["/path/to/gogcli-mcp/dist/index.js"],
      "cwd": "/path/to/gogcli-mcp",
      "env": {
        "GOG_ACCOUNT": "[email protected]"
      }
    }
  }
}

Option B — npx

{
  "mcpServers": {
    "gogcli": {
      "command": "npx",
      "args": ["-y", "gogcli-mcp"],
      "env": {
        "GOG_ACCOUNT": "[email protected]"
      }
    }
  }
}

GOG_ACCOUNT is optional — omit it to use gogcli's configured default account. Pass it per-tool-call to target a specific account dynamically.

Available Tools

Tool What it does
gog_sheets_get Read values from a range
gog_sheets_update Write values to a range
gog_sheets_append Append rows after existing data
gog_sheets_clear Clear values in a range
gog_sheets_metadata Get title, tabs, named ranges
gog_sheets_create Create a new spreadsheet
gog_sheets_find_replace Find and replace across a spreadsheet
gog_sheets_run Run any gog sheets subcommand (escape hatch)

All tools accept an optional account parameter to override the default Google account for that call.

Changes

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.
