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:

Chrome tab IDs are large numbers (e.g., 1762561083), NOT sequential indices like 1, 2, 3.
Before any operation, call tabz_list_tabs to:
active: true)mcp-cli call tabz/tabz_list_tabs '{"response_format": "json"}'
Returns:
{
"claudeCurrentTabId": 1762561083,
"tabs": [
{"tabId": 1762561065, "url": "...", "active": false},
{"tabId": 1762561083, "url": "...", "active": true}
]
}
# 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 Claude workers use tabz MCP tools simultaneously, they MUST isolate their tabs to prevent conflicts.
Each worker MUST create its own tab group on startup:
# 1. Create unique group for this worker (use session ID or UUID)
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
# Never use the user's active tab
| Do | Don't |
|---|---|
| Create own tab group at start | Use shared "Claude" group |
| Store your tabIds after opening | Rely on active: true tab |
| Target tabs by explicit ID | Assume current tab is yours |
| Clean up group when done | Leave orphaned tabs/groups |
# Close your tab group when done
mcp-cli call tabz/tabz_ungroup_tabs '{"tabIds": [<your_tab_ids>]}'
# Or close the tabs entirely
tabz_claude_group_add is for single-worker scenarios where one Claude session marks tabs it's working on. For parallel workers:
tabz_create_group with unique name (session ID)# List tabs first to sync and get IDs
mcp-cli call tabz/tabz_list_tabs '{}'
# Screenshot with explicit tabId
mcp-cli call tabz/tabz_screenshot '{"tabId": 1762561083}'
# Fill fields
mcp-cli call tabz/tabz_fill '{"selector": "#username", "value": "user@example.com"}'
mcp-cli call tabz/tabz_fill '{"selector": "#password", "value": "secret"}'
# Click submit
mcp-cli call tabz/tabz_click '{"selector": "button[type=submit]"}'
# Enable capture first
mcp-cli call tabz/tabz_enable_network_capture '{}'
# Trigger the action, then get requests
mcp-cli call tabz/tabz_get_network_requests '{}'
# Filter for specific endpoints
mcp-cli call tabz/tabz_get_network_requests '{"filter": "/api/users"}'
# List current groups
mcp-cli call tabz/tabz_list_groups '{}'
# Create a new group
