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

zenmoney-mcp AGENTS.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 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.

AGENTS.md

Project

Read-only MCP server for ZenMoney. It syncs ZenMoney data into process memory and exposes it through MCP tools and resources.

Commands

  • Install: npm install
  • Test: npm test
  • Build: npm run build
  • Publish check: npm publish --dry-run

Run npm test and npm run build before proposing code changes.

Workflow

  • Use Superpowers for code and behavior changes. Invoke the relevant Superpowers skill before taking action; do not skip a matching skill because the change looks small.
  • For new features or behavior changes, start with superpowers:brainstorming: explore project context, clarify requirements, present the design, and get user approval before implementation.
  • After the design is approved, use superpowers:writing-plans to save a task-by-task implementation plan under docs/superpowers/plans/.
  • During implementation, use superpowers:test-driven-development: no production code without a failing test first; follow red, green, refactor.
  • Before claiming code work is complete, use superpowers:verification-before-completion and run the project checks listed above.

Privacy And Safety

  • Never commit .env, .npmrc, tokens, API responses, financial records, or local cache files.
  • Do not add disk persistence for ZenMoney data without an explicit design review.
  • Do not log access tokens, full API request bodies, full API responses, or financial records.
  • This server is read-only. Do not add create, update, or delete ZenMoney tools unless explicitly requested and gated by configuration.

Package

  • Package name: @nonnname/zenmoney-mcp
  • CLI bin: zenmoney-mcp
  • Runtime entrypoint: dist/index.js
  • Source entrypoint: src/index.ts

Release Checklist

  • npm test
  • npm run build
  • npm audit --omit=dev
  • npm pack --dry-run --json
  • npm publish --dry-run
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.
