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

quickbooks-mcp CLAUDE.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 10d 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.

QuickBooks MCP Server

Project Overview

This is a Model Context Protocol (MCP) server that provides Claude with access to QuickBooks Online. It enables Claude to query, create, and edit accounting data including journal entries, bills, expenses, and reports.

This Repository Is Public

Everything published here is world-readable: commit messages, PR titles, bodies and comments, issue text, code, comments, tests and fixtures.

This server is developed against a live production QuickBooks company, so real data is always within reach while debugging. None of it belongs in anything published here. That means no company or trade names, no location or store identifiers, no chart-of-accounts names or numbers taken from the live books, no real dollar amounts, and no customer or vendor names.

Use invented fixtures instead — departments like North/South, accounts like 4000 Sales, round amounts like 100.00.

The rule that matters most in practice: when a bug is found against live data, describe the shape of the input, not the input. "A sub-account name longer than the column width" and "a value column with no title" are what make a bug reproducible; pasting the real row adds nothing a reader needs and is how live figures end up in a public changelog. The same applies to verification evidence — report what was asserted, not a dump of the books.

Redacting after the fact is awkward: issue and PR bodies can be edited, but commit messages are permanent without a history rewrite. Get it right on the way in.

Git Workflow

This repo uses a branch-and-PR workflow — never commit directly to master. All changes land via pull request.

  • "commit and push" means: branch off the latest master, commit, push, and open a PR to master with gh pr create. Then stop — PRs wait for review; do not auto-merge.
  • Start from an up-to-date master: git fetch origin && git switch -c <branch> origin/master.
  • Branch naming: type/short-descfeat/, fix/, docs/, chore/, refactor/. E.g. fix/scraper-popup, chore/bump-deps.
  • Give the PR a descriptive title and a body summarizing what changed and why.

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.
