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	$0.00602	$0.00602
Opus 5.5	$0.00241	$0.00241

Security

Grade A, and why

scan-qrcode-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 2mo 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.

Repository Guidelines

Project Structure & Module Organization

Root: README, LICENSE, and project configs.
src/: Source code for the QR code MCP server (e.g., src/server.ts, src/routes/, src/services/).
tests/: Automated tests mirroring src/ structure (e.g., tests/services/qrcode.spec.ts).
scripts/: Helper scripts for local dev or CI (optional).
assets/: Sample QR images and fixtures for tests/examples (optional).

Example layout:

src/
  server.ts
  routes/
  services/
  utils/
tests/
  services/
assets/

Build, Test, and Development Commands

npm i or pnpm i: Install dependencies.
npm run dev: Start the server in watch mode (TypeScript + nodemon/ts-node).
npm run build: Compile TypeScript to dist/.
npm test: Run unit tests with coverage.
npm run lint / npm run format: Lint and format the codebase.

Note: Add these scripts to package.json once the scaffolding is in place.

Coding Style & Naming Conventions

Language: TypeScript preferred; 2‑space indentation.
Files: kebab-case (e.g., qrcode-service.ts); tests end with .spec.ts.
Naming: camelCase for variables/functions, PascalCase for classes/types, UPPER_SNAKE_CASE for env constants.
Tools: ESLint (typescript-eslint), Prettier for formatting. Keep imports sorted and paths relative to src/.

Testing Guidelines

Framework: Vitest or Jest; aim for ≥80% line coverage on services/utils.
Structure: Mirror src/ in tests/; use fixtures in assets/.
Conventions: *.spec.ts; one behavior per test, explicit assertions.
Run: npm test locally and ensure CI passes before opening a PR.

Commit & Pull Request Guidelines

Commits: Follow Conventional Commits (e.g., feat(server): add health endpoint).
PRs: Include a clear description, linked issues (e.g., Closes #12), screenshots or logs when relevant, and notes on breaking changes or migrations.
Scope: Keep PRs small and focused; include tests and update docs.
