What is browser-mcp-fronteira-e-posicionamento?

A Portuguese-language guide to the browser MCP server’s external position and research boundaries. It covers comparisons with browser-use and Playwright MCP, which are tools for automating browsers.

Use it when writing public documentation, comparing browser automation tools, describing the project’s niche, or choosing an open research problem.

It helps developers avoid unsupported public claims and keeps comparisons current, since competing tools and their capabilities can change.

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	$0.00133	$0.03234
Opus 5.5	$0.00053	$0.01294
Sonnet 5.5	$0.00027	$0.00647
Haiku 4.5	$0.00013	$0.00323

Measured 2mo ago against content hash ff01b39eb223, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

browser-mcp-fronteira-e-posicionamento 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.

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.
