An MCP server for brawsr, a browser-session system with saved checkpoints and branching. It supports actions such as rewinding, forking, viewing lineage, and managing session lifecycles.

Use it to manage brawsr browser sessions, create or restore checkpoints, fork an existing session, inspect its history, and control its lifecycle. It requires three environment variables.

It helps an agent preserve browser state and return to earlier points instead of losing progress or repeating a workflow from the beginning.

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.

Security

Grade A, and why

brawsr 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 yesterday.

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.
