Before any browser work, create a tab group to isolate your tabs:
# Create a unique group for this session
mcp-cli call tabz/tabz_create_group '{"title": "Claude Working", "color": "purple"}'
# Returns: {"groupId": 123, ...}
# Open all URLs into YOUR group
mcp-cli call tabz/tabz_open_url '{"url": "https://example.com", "newTab": true, "groupId": 123}'
Why this matters:
Always use explicit tabId from tabs you opened - never rely on the active tab.
Always check the schema first:
mcp-cli info tabz/<tool_name>
Create new terminal tabs via REST API:
TOKEN=$(cat /tmp/tabz-auth-token)
curl -X POST http://localhost:8129/api/spawn \
-H "Content-Type: application/json" \
-H "X-Auth-Token: $TOKEN" \
-d '{"name": "Worker", "workingDir": "~/projects", "command": "claude"}'

Chrome tab IDs are large numbers (e.g., 1762561083), NOT sequential indices.
mcp-cli call tabz/tabz_list_tabs '{"response_format": "json"}'
# DON'T rely on implicit current tab
mcp-cli call tabz/tabz_screenshot '{}' # May target wrong tab!
# DO use explicit tabId
mcp-cli call tabz/tabz_list_tabs '{}' # Get IDs first
mcp-cli call tabz/tabz_screenshot '{"tabId": 1762561083}' # Target explicit tab
When multiple workers use tabz tools simultaneously:
Each worker MUST create its own tab group:
# 1. Create unique group for this worker
SESSION_ID=$(tmux display-message -p '#{session_name}' 2>/dev/null || echo "worker-$$")
mcp-cli call tabz/tabz_create_group "{\"title\": \"$SESSION_ID\", \"color\": \"blue\"}"
# 2. Open tabs IN that group
mcp-cli call tabz/tabz_open_url '{"url": "https://example.com", "groupId": <group_id>}'
# 3. Always use explicit tabIds from YOUR group
mcp-cli call tabz/tabz_list_tabs '{}'
mcp-cli call tabz/tabz_screenshot '{"tabId": 1762561083}'
mcp-cli call tabz/tabz_fill '{"selector": "#username", "value": "user@example.com"}'
mcp-cli call tabz/tabz_fill '{"selector": "#password", "value": "secret"}'
mcp-cli call tabz/tabz_click '{"selector": "button[type=submit]"}'
mcp-cli call tabz/tabz_enable_network_capture '{}'
# Trigger the action, then:
mcp-cli call tabz/tabz_get_network_requests '{"filter": "/api/"}'
TOKEN=$(cat /tmp/tabz-auth-token)
curl -X POST http://localhost:8129/api/spawn \
-H "Content-Type: application/json" \
