Page Structure

Build, inspect, and manage page elements and components in the Webflow Designer.

Important Note

ALWAYS use Webflow MCP tools for all operations:

• Use Webflow MCP's webflow_guide_tool to get best practices before any other tool call
• Use Webflow MCP's data_sites_tool with action list_sites to identify the target site
• Use Webflow MCP's data_pages_tool with action list_pages to find the target page by name or slug — headless, works against any page
• Use Webflow MCP's data_pages_tool with action create_page to create new pages — headless
• Use Webflow MCP's data_element_tool with action get_all_elements or query_elements to retrieve or filter page elements — headless, pass the page's ID directly
• Use Webflow MCP's data_element_builder to create new elements — headless, pass the page's ID and a parent element ID
• Use Webflow MCP's data_element_tool with action set_attributes, set_text, set_style, or set_link to modify elements — headless
• Use Webflow MCP's element_snapshot_tool to get visual previews of elements before and after changes — this is a Designer tool and requires a Designer connection
• Use Webflow MCP's data_style_tool to create and update styles on elements — headless
• Use Webflow MCP's webflow_guide_tool to check supported style properties
• Use Webflow MCP's data_component_tool with action get_all_components or query_components to list site components — headless
• Use Webflow MCP's data_component_tool with action get_component to inspect a component's metadata — headless
• Use Webflow MCP's data_element_tool scoped with scope_component_id to inspect or edit a component's internal elements (its "content") — headless
• Use Webflow MCP's data_component_props_tool to manage prop definitions and set prop values on component instances — headless
• Use Webflow MCP's data_component_variants_tool to manage variants and per-variant style overrides — headless
• Use Webflow MCP's data_component_tool with action insert_component_instance or unlink_component_instance to manage component instances on a page — headless, not Designer-gated
• Use Webflow MCP's designer_tool only for actions that need a live canvas: get_current_page/switch_page (what's open in Designer right now), select_element/get_selected_element (interactive canvas selection), create_page_folder (page folders are Designer-only, unlike page creation itself), and open_component_view (viewing a component's canvas)
• DO NOT use any other tools or methods for Webflow operations
• All tool calls must include the required context parameter (15-25 words, third-person perspective)
• Designer connection is required for designer_tool actions and for element_snapshot_tool. Building, styling, inspecting, and updating elements, components, props, and variants (the data_ tools) runs headlessly against an explicit page ID from data_pages_tool's list_pages — but the before/after visual snapshots this skill relies on for safe mutation need Designer open and connected. If Designer isn't available, skip the snapshot steps and rely on query_elements output to describe changes instead.

Instructions

Phase 1: Discovery

1. Call webflow_guide_tool first — always the first MCP tool call in any workflow
2. Get the site: Use data_sites_tool with action list_sites to identify the target site. If only one site exists, use it automatically.
3. Get the target page: Use data_pages_tool with action list_pages to find the page by name or slug — no Designer connection needed. If the user is actively working in an open Designer session and wants "the page I have open," use designer_tool with action get_current_page instead.
4. If user specifies a different page: Just use that page's ID directly in later calls — no page "switch" is needed for headless operations. Only use designer_tool with action switch_page if the user wants the Designer canvas itself to navigate there.
5. Identify the task type:
   • Inspect: List elements, view structure, preview → go to Phase 2
   • Build/Modify/Delete: Add, update, restructure, remove → go to Phase 3
   • Components: List, inspect, update → go to Phase 2 or Phase 3 depending on read vs write

Phase 2: Inspection (read-only operations)

6. List page elements: Use data_element_tool with get_all_elements (or query_elements to filter by type/text/attribute) to retrieve page structure, passing the page ID from Phase 1. Present a summary of sections, elements, and nesting.
7. Preview elements: Use element_snapshot_tool to get visual previews of specific sections — requires Designer
8. List components: Use data_component_tool with action get_all_components or query_components to list all site components
9. Inspect a component: Use data_component_tool with action get_component for metadata (props, variants), or data_element_tool with scope_component_id set to the component's ID to inspect its internal elements

Phase 3: Planning (before any mutation)

Before creating, updating, or deleting anything: 10. Snapshot current state: Use element_snapshot_tool to capture the area being changed — requires Designer; if unavailable, describe the current state from query_elements output instead 11. Present the plan: Describe exactly what will be created, modified, or deleted 12. Request explicit confirmation: Ask the user before proceeding: - "Would you like me to proceed with these changes?" - "Shall I go ahead and create this?" - "Do you want me to apply these changes?" - "Before I make changes, here's what I'll do: [plan]. Confirm to proceed." 13. For destructive operations (delete, restructure): Require "confirm" or "delete", warn about child elements that will also be affected

Phase 4: Execution (after confirmation only)

14. Build elements: Use data_element_builder to create new elements (max 3 levels deep), passing the page ID and the parent element ID. For deeper structures, build in multiple passes.
15. Style elements: Use data_style_tool to apply or update styles on created or existing elements
16. Modify elements: Use data_element_tool with set_attributes, set_text, set_style, or set_link to update attributes, text, or links
17. Update components: Use data_element_tool (scoped with scope_component_id) to edit a component's internal elements; data_component_props_tool to change prop definitions or instance prop values; data_component_variants_tool to manage variants; data_component_tool with insert_component_instance/unlink_component_instance to add or unlink instances on a page
18. Create pages: Use data_pages_tool with action create_page. To create a page folder, use designer_tool with action create_page_folder — this specific action requires a Designer connection

Phase 5: Verification

19. Snapshot the result: Use element_snapshot_tool to capture the new state — requires Designer; if unavailable, summarize the change from the tool response instead
20. Report what changed: Summarize the changes made

6. After confirmation: call data_element_builder with grid structure
7. Call data_style_tool to set grid layout properties
8. Call element_snapshot_tool to show the result

Guidelines

• webflow_guide_tool always first — before any other MCP tool in every workflow
• Snapshot before and after — use element_snapshot_tool before mutations and after to show results
• Never silently mutate — every write operation requires explicit user confirmation
• Headless for building and editing — get the page ID once via data_pages_tool's list_pages, then pass it directly to data_element_tool, data_element_builder, and data_style_tool. Reach for designer_tool only when the task specifically needs the live canvas (current-page detection, interactive selection, page folders, component canvas view).
• Visual snapshots need Designer — element_snapshot_tool is a Designer tool; if Designer isn't connected, fall back to describing changes from query_elements/tool response data instead of skipping the before/after check entirely.
• Batch changes need itemized preview — if modifying multiple elements, list each change
• Prefer Webflow's native layout tools (Grid, Flexbox) over manual positioning
• Components shared across pages should be updated via data_element_tool scoped to the component (changes propagate to all instances)
• Component instance management (insert_component_instance, unlink_component_instance) is headless via data_component_tool — not Designer-gated
• data_element_builder supports max 3 levels per call — build deeper structures in stages
• Check webflow_guide_tool for supported style properties when unsure
