# Per-user isolated playwright-mcp HTTP server — the browser MCP each user's
|

|
|
# Claude Code sessions connect to (user-scope `.claude.json` entry "playwright"
|
||
|
|
# -> http://localhost:<PLAYWRIGHT_PORT>/mcp). System-level TEMPLATE unit (one
|
||
|
|
# committed file, one instance per OS user: playwright-mcp@<user>.service), so
|
||
|
|
# it is reproducible from git and root-manageable WITHOUT systemd --user / linger.
|
||
|
|
# Installed to /etc/systemd/system by setup-devvm.sh; enabled per-user by
|
||
|
|
# t3-provision-users.sh. Supersedes the hand-made ~/.config/systemd/user units.
