n8n_deactivate_workflow
Stop a workflow from listening to triggers. Deactivating prevents automatic execution but preserves workflow configuration. Use before making structure changes.
n8n_execute_workflow
Manually trigger workflow execution with optional input data. Useful for testing or API-driven workflows without webhooks. Returns execution ID to track progress. Does not require workflow to be active.
n8n_get_workflow_tags
Retrieve tags assigned to a workflow for categorization. Returns array of tag names. Use this to understand workflow organization before bulk operations.
n8n_update_workflow_tags
Assign tags to a workflow for organization and filtering. Replaces existing tags completely. Use tags like "production", "testing", or team names. Create missing tags automatically.
n8n_list_executions
Retrieve execution history with status, timestamps, and workflow info. Filter by workflow ID or get all executions. Returns execution ID, status (success/error/running), start time, and workflow name. Use this to monitor automation performance or debug failures.
n8n_get_execution
Get detailed execution data including node outputs, error messages, and timing. Returns full execution log with data passed between nodes. Essential for debugging failed workflows or understanding data flow.
n8n_delete_execution
Remove execution record from history to save storage or clean up test runs. Permanently deletes execution data. Use after debugging or to maintain clean execution logs.
n8n_retry_execution
Rerun a failed execution with the same input data. Useful for transient errors like network timeouts. Creates new execution while preserving original execution log. Only works with failed executions.
n8n_create_credential
Store new API credentials for services like GitHub, Slack, or databases. Provide credential type, descriptive name, and authentication data. Use get_credential_schema first to see required fields for each type.
n8n_update_credential
Update credential name or authentication data. Use this when rotating API keys or changing OAuth tokens. Workflows using this credential will use updated auth immediately.
n8n_delete_credential
Remove stored credential. Cannot delete credentials currently used in active workflows. Deactivate dependent workflows first. Use with caution as this may break workflows.
n8n_get_credential_schema
Get required fields and format for a credential type before creating it. Returns field names, types, and whether fields are required. Use this to understand what authentication data is needed.
n8n_list_tags
Retrieve all available tags for workflow organization. Returns tag ID and name. Use this before assigning tags to workflows or to see your tagging structure.
n8n_get_tag
Get tag details including ID and name. Rarely needed - use list_tags for most cases. Useful for validating tag existence before bulk operations.
n8n_create_tag
Create new tag for workflow categorization. Use meaningful names like "production", "staging", "team-marketing", or "urgent". Tags help filter and organize workflows.
n8n_update_tag
Rename an existing tag. All workflows using this tag will automatically reflect the new name. Use this to standardize tag naming across workflows.
n8n_delete_tag
Remove tag from system. Automatically removes this tag from all workflows using it. Tag removal does not affect workflows themselves, only the tag association.
n8n_list_users
Retrieve all n8n users with their roles and status. Only available to instance owner. Returns user ID, email, role (owner/admin/member), and disabled status. Use this for user management and auditing.
n8n_get_user
Get detailed user information by ID or email. Only available to instance owner. Returns user profile including role and account status. Use this to verify user details before role changes.
n8n_delete_user
Remove user from n8n instance. Only available to instance owner. Cannot delete the owner account. Deleted users lose access immediately. Workflows created by this user remain intact.
n8n_update_user_role
Change user permission level. Only available to instance owner. Admin can manage workflows and credentials. Member has view-only or limited edit access. Cannot change owner role.
