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 | $0.00524 | $0.00524 |
| Opus 5 | $0.00262 | $0.00262 |
| Sonnet 5 | $0.00105 | $0.00105 |
| Haiku 4.5 | $0.00052 | $0.00052 |
Grade A, and why
mcp-accessibility-scanner 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 today.
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
- This repository is a Node.js + TypeScript MCP server for automated accessibility scanning and browser automation.
- Runtime entrypoints are
cli.jsfor the published CLI andsrc/index.ts/src/program.tsfor source-level behavior. - Built output lives in
lib/and should be treated as generated artifacts. - Keep changes focused and minimal; fix root causes instead of layering workarounds.
- Match the existing TypeScript and ESM style already used in
src/. - Do not rename the published package, binary name, or exported tool names unless explicitly requested.
- Update
README.mdwhen user-facing behavior, commands, configuration, or tool surfaces change. - Prefer editing source files in
src/; do not hand-edit generated files inlib/. src/tools/: MCP tool implementations, including accessibility scans and browser actions.src/mcp/: MCP transport/server helpers.src/extension/andsrc/vscode/: editor/extension integration code.src/utils/: shared utilities.- Use nearby Vitest coverage when adding or changing behavior that is already tested.
- Install dependencies:
npm install - Build:
npm run build - Lint:
npm run lint - Test:
npm test - Knip:
npm run knip - Coverage:
npm run test:coverage - Docker smoke test:
npm run test:docker - Tool latency benchmark:
npm run bench(see the Benchmarking section ofREADME.md; build first, and compare revisions withnpm run bench:compare) - TypeScript config is driven by
tsconfig.jsonandtsconfig.all.json. - Accessibility behavior centers around Axe + Playwright integrations in
src/tools/axe.ts,src/tools/auditSite.ts,src/tools/auditKeyboard.ts, and related helpers. - Keep output and report paths compatible with the current README and CLI expectations.
- Reuse existing helpers before introducing new abstractions.
- Prefer targeted validation first, then broader checks if needed.
- When touching build, lint, or test behavior, run the relevant npm script before finalizing.
- Before committing or pushing, self-review your diff against
.codex/skills/pre-push-review/SKILL.md— a checklist of the recurring defect patterns automated PR review keeps finding in this repo. - Avoid introducing ignored or generated artifacts into version control;
.gitignorealready excludeslib/,coverage/, Playwright reports, and similar outputs.
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.
