Webflow Mcp:cms Collection Setup

CMS Collection Setup

Create a new CMS collection with custom fields, relationships, and proper configuration.

Important Note

ALWAYS use Webflow MCP tools for all operations:

• Use Webflow MCP's webflow_guide_tool to get best practices before starting
• Use Webflow MCP's data_sites_tool with action list_sites to identify available sites
• Use Webflow MCP's data_sites_tool with action get_site to retrieve site details and plan limits
• Use Webflow MCP's data_cms_tool with action get_collection_list to check for naming conflicts
• Use Webflow MCP's data_cms_tool with action create_collection to create the collection
• Use Webflow MCP's data_cms_tool with action create_collection_static_field to create static fields
• Use Webflow MCP's data_cms_tool with action create_collection_option_field to create option fields
• Use Webflow MCP's data_cms_tool with action create_collection_reference_field to create reference/multi-reference fields
• Use Webflow MCP's data_cms_tool with action get_collection_details to verify collection was created correctly
• 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)

Instructions

Phase 1: Site Selection & Discovery

1. Get site information: Use Webflow MCP's data_sites_tool with action list_sites to identify target site
2. Confirm site: Ask user to select site if multiple available
3. Check plan limits: Use Webflow MCP's data_sites_tool with action get_site to verify collection limits
4. List existing collections: Use Webflow MCP's data_cms_tool with action get_collection_list to check for conflicts
5. Validate naming: Ensure new collection name doesn't conflict with existing

Phase 2: Requirements Gathering

6. Get collection details: Ask user for:
   • Collection display name (e.g., "Blog Posts")
   • Singular name (e.g., "Blog Post")
   • Optional: Custom slug (default: auto-generated from display name)
7. Get field definitions: For each field, gather:
   • Field name (e.g., "Author Name", "Publish Date")
   • Field type (Text, Rich Text, Image, Option, Reference, etc.)
   • Required vs optional
   • Any validation rules or help text
8. Identify relationships: Determine if collection needs:
   • Reference fields (one-to-many relationships)
   • Multi-reference fields (many-to-many relationships)
   • Option fields (controlled vocabulary)

Phase 3: Schema Validation & Planning

9. Validate field types: Check all field types are supported
10. Check field limits: Ensure within Webflow limits:
    • Max fields per collection: varies by plan
    • Max 5 multi-reference fields per collection
11. Plan creation order: Organize fields by dependency:
    • Create collections in order if references exist
    • Create referenced collections first
    • Create option fields before reference fields
12. Generate preview: Show complete schema with all fields

Phase 4: User Approval

13. Show complete preview: Display:
    • Collection name and slug
    • All fields with types and properties
    • Any relationships to other collections
    • Plan limit verification
14. Validate schema: Check for common issues:
    • Missing required fields (name, slug always required)
    • Invalid field types
    • Reference to non-existent collections
    • Exceeding plan limits
15. Request confirmation: Wait for explicit "create" approval

Phase 5: Collection Creation

16. Create collection: Use Webflow MCP's data_cms_tool with action create_collection with:
    • Display name
    • Singular name
    • Optional slug
17. Capture collection ID: Save for field creation
18. Show progress: Report collection created successfully

Phase 6: Field Creation

19. Create fields in order: For each field:
    • Use appropriate creation tool based on type
    • Static fields: data_cms_tool with action create_collection_static_field
    • Option fields: data_cms_tool with action create_collection_option_field
    • Reference fields: data_cms_tool with action create_collection_reference_field
20. Set field properties:
    • Display name
    • Required flag
    • Help text (if provided)
    • Validation rules (if applicable)
21. Show progress: Report each field created
22. Handle errors: If field creation fails, report and continue

Phase 7: Verification & Reporting

23. Verify collection: Use Webflow MCP's data_cms_tool with action get_collection_details to retrieve full schema
24. Confirm all fields: Check that all requested fields were created
25. Generate report: Show:
    • Collection ID
    • Collection name and slug
    • All fields created with IDs
    • Any failures or warnings
26. Provide next steps: Suggest:
    • Use bulk-cms-update to add initial items
    • Create collection pages in Designer
    • Set up relationships if applicable

- Tags: This should be a multi-reference field

This requires creating additional collections first:
1. Brands collection
2. Tags collection

Then we can create Products with references to them.

Would you like me to:
A) Create all three collections (Brands, Tags, Products)
B) Just create Products (you'll add relationships later)
C) Modify the requirements

Your choice? (A/B/C)

Guidelines

Phase 1: Discovery Best Practices

Site Selection:

• Always use data_sites_tool with action list_sites to get available sites
• Never assume site ID
• Verify user has correct site selected

Plan Limit Checking:

Check limits before creation:
- Starter: 1 collection, 50 items
- Basic: 2 collections, 200 items
- CMS: 20 collections, 2,000 items
- Business: 40 collections, 10,000 items
- Enterprise: Custom

Warn user if approaching limits.

Naming Conflict Prevention:

• Check existing collection names
• Suggest alternative names if conflict
• Validate slug availability

Phase 2: Requirements Gathering Best Practices

Display Name vs Singular Name:

Display Name: Plural form shown in CMS
Singular Name: Singular form for individual items

Examples:
- Display: "Blog Posts" → Singular: "Blog Post"
- Display: "Team Members" → Singular: "Team Member"
- Display: "Products" → Singular: "Product"
- Display: "Categories" → Singular: "Category"

Field Naming Conventions:

✅ Good names:
- author-name (descriptive, hyphenated)
- publish-date (clear purpose)
- featured-image (specifies which)
- main-content (explains use)

❌ Bad names:
- text1 (meaningless)
- field (too generic)
- data (unclear)
- img (which image?)

Detecting Relationships:

If user says:
"... with author" → Likely reference field
"... with tags" → Likely multi-reference field
"... with category" → Likely reference field
"... with related products" → Likely multi-reference field

Ask clarifying questions:
- Is [author] the same across items? → Reference
- Can items have multiple [tags]? → Multi-reference
- Do you have a [Categories] collection? → Check existence

Phase 3: Schema Validation Best Practices

Field Type Validation:

Common field type mappings:

User says... → Field type:
"title", "name" → PlainText
"description", "summary" → PlainText (long)
"content", "bio", "article" → RichText
"photo", "image", "thumbnail" → Image
"gallery", "photos" → MultiImage
"document", "PDF", "file" → File
"video" → Video
"link", "URL", "website" → Link
"email" → Email
"phone", "mobile" → Phone
"price", "cost", "amount" → Number
"date", "published", "deadline" → DateTime
"featured", "active", "published" → Switch
"status", "type", "category" → Option (if fixed choices)
"color", "theme" → Color

Multi-Reference Limit Check:

Count multi-reference fields requested:

If > 5:
⚠️ Warning: Collection Limit Exceeded

Webflow allows max 5 multi-reference fields per collection.

You requested: 7 multi-reference fields

Options:
1. Choose 5 most important relationships
2. Convert some to reference fields (one-to-many)
3. Create bridging collections
4. Use option fields for simple categorization

Which would you prefer?

Dependency Resolution:

For reference fields:
1. Check if referenced collection exists
2. If not, add to creation queue
3. Create in correct order

Example:
Products needs:
- Categories collection (create first)
- Brands collection (create first)
Then create Products

Phase 4: Preview Best Practices

Complete Preview Format:

📋 Preview: Create "[Collection Name]"

Collection Details:
├── Display Name: [Name]
├── Singular Name: [Singular]
├── Slug: [slug]
└── Site: [Site Name]

Fields ([X] total):
├── name (PlainText, required) ← Auto-created
├── slug (PlainText, required) ← Auto-created
├── [field-1] ([Type], [required/optional])
├── [field-2] ([Type], [required/optional])
│   [Additional info if Option or Reference]
└── [field-n] ([Type], [required/optional])

Relationships:
├── [field] → [Collection] (Reference)
└── [field] → [Collection] (MultiReference)

✅ Validation Results:
- Collection name available: Yes
- Within plan limits: X/Y collections
- Multi-reference count: X/5
- All field types valid: Yes
- Dependencies resolved: Yes

⚠️ Type "create" to proceed.

Validation Checks:

Before showing preview:
1. ✅ Collection name available
2. ✅ Within plan collection limit
3. ✅ All field types supported
4. ✅ Multi-reference limit ≤ 5
5. ✅ Referenced collections exist or queued
6. ✅ No circular dependencies
7. ✅ Field names follow conventions

Phase 5: Creation Best Practices

Collection Creation:

Required fields:
- displayName (required)
- singularName (required)
- slug (optional, auto-generated if omitted)

Always include both names for clarity:
✅ {"displayName": "Blog Posts", "singularName": "Blog Post"}
❌ {"displayName": "Blog Posts"} (missing singular)

Error Handling:

If collection creation fails:
❌ Collection Creation Failed

Error: [Error message from API]

Common causes:
- Collection name already exists
- Invalid characters in name/slug
- Plan limit reached
- API authentication issue

Would you like to:
1. Try a different collection name
2. Check existing collections
3. Upgrade plan
4. Cancel operation

Phase 6: Field Creation Best Practices

Field Creation Order:

Create fields in this order:
1. Static fields (Text, Rich Text, Number, etc.)
2. Option fields (with options defined)
3. Reference fields (after referenced collections exist)

For each field:
- Set displayName
- Set isRequired flag
- Add helpText if provided by user
- Set validation rules if applicable

Field Creation Tools:

Field Type → Tool to use:

PlainText, RichText, Email, Phone, Link, Number,
Image, MultiImage, File, Video, DateTime, Switch, Color
→ data_cms_tool with action create_collection_static_field

Option
→ data_cms_tool with action create_collection_option_field
   (requires metadata.options array)

Reference, MultiReference
→ data_cms_tool with action create_collection_reference_field
   (requires metadata.collectionId)

Progress Reporting:

For each field created:
✅ [field-name] ([FieldType])

If field fails:
❌ [field-name] - [Error message]

Continue with remaining fields even if one fails.
Report all failures at end.

Option Field Creation:

{
  "type": "Option",
  "displayName": "Status",
  "isRequired": false,
  "metadata": {
    "options": [
      {"name": "Draft"},
      {"name": "Published"},
      {"name": "Archived"}
    ]
  }
}

Notes:
- Options have name property
- Options cannot have ID (auto-generated)
- Minimum 2 options required
- Maximum: unlimited

Reference Field Creation:

{
  "type": "Reference",
  "displayName": "Author",
  "isRequired": true,
  "metadata": {
    "collectionId": "abc123..."
  }
}

For MultiReference:
{
  "type": "MultiReference",
  "displayName": "Tags",
  "metadata": {
    "collectionId": "def456..."
  }
}

Notes:
- Must provide collectionId of referenced collection
- Referenced collection must already exist
- Max 5 MultiReference fields per collection

Phase 7: Verification Best Practices

Post-Creation Verification:

After creating collection and fields:
1. Call data_cms_tool with action get_collection_details with collection ID
2. Verify all fields present
3. Check field properties match request
4. Confirm relationships configured correctly

Final Report Format:

4. Referenced Collection Not Found:

❌ Referenced Collection Not Found

Cannot create reference field to "Authors" collection.

Issue: "Authors" collection doesn't exist yet.

Solutions:
1. Create "Authors" collection first
2. Remove reference field for now
3. Let me create both collections in order

Your choice? (1/2/3)

5. Multi-Reference Limit Exceeded:

❌ Too Many Multi-Reference Fields

You requested 6 multi-reference fields.
Webflow limit: 5 per collection

Requested:
1. Tags
2. Categories
3. Related Products
4. Features
5. Certifications
6. Compatible Products ← Exceeds limit

Choose 5 to keep, or convert one to Reference field.

Phase 9: Advanced Scenarios

Self-Referencing Collections:

Example: Categories with parent categories

Collection: Categories
Fields:
├── name (PlainText, required)
├── slug (PlainText, required)
├── parent-category (Reference → Categories)
└── level (Number) - 1, 2, 3 for hierarchy

Implementation:
{
  "type": "Reference",
  "displayName": "Parent Category",
  "isRequired": false,
  "metadata": {
    "collectionId": "[same-collection-id]"
  }
}

Note: Must create collection first, then add self-reference field

Multi-Collection Setup:

When creating multiple related collections:

1. Identify dependencies:
   - Which collections reference others?
   - What's the creation order?

2. Create in order:
   - Independent collections first
   - Dependent collections after

3. Show overall progress:
   [1/4] Creating Categories...
   [2/4] Creating Brands...
   [3/4] Creating Tags...
   [4/4] Creating Products...

4. Report collectively:
   All 4 collections created successfully!

Complex Option Fields:

For complex dropdowns:

User: "Create status field with Draft, In Review, Approved, Published, Archived"

Option field with 5 choices:
{
  "type": "Option",
  "displayName": "Status",
  "isRequired": true,
  "metadata": {
    "options": [
      {"name": "Draft"},
      {"name": "In Review"},
      {"name": "Approved"},
      {"name": "Published"},
      {"name": "Archived"}
    ]
  }
}

Tip: Use workflow order for options
