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

MCP_DOCS 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 3d 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.

Origin

This is a copy

100% identical to playwright-mcp CLAUDE.md — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Never add Co-Authored-By agents in commit message. Branch naming for issue fixes: fix-<issue-number>

Rolling Playwright

  1. Run node roll.js (or npm run roll) to bump playwright, playwright-core, and @playwright/test, refresh config.d.ts, and regenerate the README. The script prints the resolved version — use its suffix for the branch name.
  2. Create a branch: git checkout -b roll-pw-<version-suffix>.
  3. Run npm test. Only proceed if all tests pass.
  4. Commit with chore: roll Playwright to <version>, push, and open a PR against microsoft/playwright-mcp with the same title.

Preparing a Release

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.
