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

guides 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.

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.

ServalSheets Skill Guide for Claude

This guide helps Claude (and other AI assistants) use ServalSheets MCP server effectively.

Overview

ServalSheets provides 25 tools with 407 actions for comprehensive Google Sheets operations. It's production-grade with safety rails, semantic range resolution, and intelligent batching.

MCP Protocol Notes (2025-11-25)

ServalSheets follows MCP 2025-11-25. Use protocol-level features when available.

  • Tool results are MCP CallToolResult. Prefer structuredContent.response; check response.success and read response.error when false. isError may be set.
  • Tool inputs are wrapped under request (e.g., { request: { action: 'read', ... } }).
  • Tool annotations are provided (readOnlyHint, destructiveHint, idempotentHint, openWorldHint). Use them to choose safe operations and confirm destructive changes.
  • Resources:
    • sheets:///{spreadsheetId} returns spreadsheet metadata (properties + sheet list).
    • sheets:///{spreadsheetId}/{range} returns range values (A1 notation; URL-encoded).
    • knowledge:///formulas/financial.json, knowledge:///formulas/lookup.json, knowledge:///formulas/key-formulas.json
    • knowledge:///templates/common-templates.json Use resources/list and resources/read to discover and load.
  • Prompts: use prompts/list to discover the full current set. Common starter workflows include welcome, test_connection, first_operation, analyze_spreadsheet, transform_data, create_report, and clean_data.
  • Long operations may emit MCP progress notifications. Treat them as status only.
  • Large reads may return truncated: true and resourceUri. You can read the URI with the range resource; if you cannot fetch it, request a narrower range or use batch reads.

Core Capabilities

1. Data Operations (sheets_data)

What it does: Read, write, append, and batch operations on cell values

Best practices:

  • Use valueRenderOption: 'FORMATTED_VALUE' for human-readable data
  • Use valueRenderOption: 'UNFORMATTED_VALUE' for calculations
  • Always specify valueInputOption when writing (typically 'USER_ENTERED' for formulas)
  • Use batch operations for multiple ranges to save API calls

What ships with it

40 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
