Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00049 | $0.00752 |
| Opus 5 | $0.00024 | $0.00376 |
| Sonnet 5 | $0.00010 | $0.00150 |
| Haiku 4.5 | $0.00005 | $0.00075 |
Grade A, and why
install-playwright-mcp 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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Adds browser automation to your agent: navigate, screenshot, click, fill forms, intercept network. Repository: https://github.com/microsoft/playwright-mcp
Arguments
All optional — anything not passed is asked in Step 1.
| Token | Meaning |
|---|---|
claude / copilot |
which agent to configure |
headed / headless |
browser mode (headed is the default) |
Quick Start
Ask the user two questions, then run the bundled script.
Step 1 — Collect parameters
Use vscode_askQuestions with:
- agent — which agent to configure
- options:
claude,copilot
- options:
- mode — browser mode
- options:
headed(default, shows browser window),headless
- options:
Step 2 — Run the installer
Find this skill's directory from the SKILL.md path, then run:
PROJECT_ROOT="<workspace-root>" \
bash .agent-settings/skills/tools/install-playwright-mcp/scripts/install.sh \
--agent <agent> \
[--headless]
- Set
PROJECT_ROOTto the user's current workspace folder - Add
--headlessonly when the user chose headless mode - The script merges into any existing config file; it will not overwrite other servers
Step 3 — Confirm
Tell the user: Restart your agent to load Playwright MCP.
What Gets Written
Copilot (.vscode/mcp.json):
{
"servers": {
"playwright": {
"command": "npx",
"args": ["@playwright/mcp@latest"]
}
}
}
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
