Would love if there is a way to parallelize playwright mcp using multiple agents and such, but it seems it's a fundamental limitation of that MCP that only on instance/tab can be controlled.

Chrome MCP is much slower and by default pretty much unusable because Claude seems to prefer to read state from screenshots. Also, no Firefox/Safari support means no cross-browser testing.

There appears to be https://github.com/sumyapp/playwright-parallel-mcp which may be worth trying.
