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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00033 | $0.00473 |
| Opus 5 | $0.00016 | $0.00236 |
| Sonnet 5 | $0.00007 | $0.00095 |
| Haiku 4.5 | $0.00003 | $0.00047 |
Grade A, and why
browserbase-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 4d 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.
What it actually says
Browserbase
Allow LLMs to control a browser with Browserbase and Stagehand for AI-powered web automation, intelligent data extraction, and screenshot capture.
When to use
- Use Browserbase only when the task directly involves the relevant service, SaaS product, platform, or technology.
Connection
Docker stdio
{
"command": "docker",
"args": [
"run",
"--rm",
"-i",
"-e",
"BROWSERBASE_API_KEY",
"-e",
"BROWSERBASE_PROJECT_ID",
"-e",
"GEMINI_API_KEY",
"mcp/browserbase"
]
}
MCP instructions
- Use the MCP tools only for the user-requested service workflow and prefer read-only operations by default.
- Confirm the target account, workspace, project, repository, or dataset before actions that can read private data or mutate remote state.
- This server requires authorization or environment-provided credentials; ask the user before connecting or requesting access.
Docker launch notes
- Launch through Docker stdio with
docker run --rm -i -e BROWSERBASE_API_KEY -e BROWSERBASE_PROJECT_ID -e GEMINI_API_KEY mcp/browserbase. - Confirm required environment variables before launch: BROWSERBASE_API_KEY, BROWSERBASE_PROJECT_ID, GEMINI_API_KEY.

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.

browserbase-mcp is a skill published in the GitHub repository Friz-zy/ai-capability-registry (9 stars, last pushed 8d ago), licensed MIT. It adds 33 tokens to every session and 473 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
