Create a new CMS collection in Webflow with specified fields and relationships. Use when setting up blog posts, products, team members, portfolios, or other content types with custom fields.
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_toolto get best practices before starting - Use Webflow MCP's
data_sites_toolwith actionlist_sitesto identify available sites - Use Webflow MCP's
data_sites_toolwith actionget_siteto retrieve site details and plan limits - Use Webflow MCP's
data_cms_toolwith actionget_collection_listto check for naming conflicts - Use Webflow MCP's
data_cms_toolwith actioncreate_collectionto create the collection - Use Webflow MCP's
data_cms_toolwith actioncreate_collection_static_fieldto create static fields - Use Webflow MCP's
data_cms_toolwith actioncreate_collection_option_fieldto create option fields - Use Webflow MCP's
data_cms_toolwith actioncreate_collection_reference_fieldto create reference/multi-reference fields - Use Webflow MCP's
data_cms_toolwith actionget_collection_detailsto verify collection was created correctly - DO NOT use any other tools or methods for Webflow operations
- All tool calls must include the required
contextparameter (15-25 words, third-person perspective)
Instructions
Phase 1: Site Selection & Discovery
- Get site information: Use Webflow MCP's
data_sites_toolwith actionlist_sitesto identify target site - Confirm site: Ask user to select site if multiple available
- Check plan limits: Use Webflow MCP's
data_sites_toolwith actionget_siteto verify collection limits - List existing collections: Use Webflow MCP's
data_cms_toolwith actionget_collection_listto check for conflicts - Validate naming: Ensure new collection name doesn't conflict with existing
Phase 2: Requirements Gathering
- 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)
- 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
- 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
- Validate field types: Check all field types are supported
- Check field limits: Ensure within Webflow limits:
- Max fields per collection: varies by plan
- Max 5 multi-reference fields per collection
- Plan creation order: Organize fields by dependency:
- Create collections in order if references exist
- Create referenced collections first
- Create option fields before reference fields
- Generate preview: Show complete schema with all fields
Phase 4: User Approval
- Show complete preview: Display:
- Collection name and slug
- All fields with types and properties
- Any relationships to other collections
- Plan limit verification
- Validate schema: Check for common issues:
- Missing required fields (name, slug always required)
- Invalid field types
- Reference to non-existent collections
- Exceeding plan limits
- Request confirmation: Wait for explicit "create" approval
Phase 5: Collection Creation
- Create collection: Use Webflow MCP's
data_cms_toolwith actioncreate_collectionwith:- Display name
- Singular name
- Optional slug
- Capture collection ID: Save for field creation
- Show progress: Report collection created successfully
Phase 6: Field Creation
- Create fields in order: For each field:
- Use appropriate creation tool based on type
- Static fields:
data_cms_toolwith actioncreate_collection_static_field - Option fields:
data_cms_toolwith actioncreate_collection_option_field - Reference fields:
data_cms_toolwith actioncreate_collection_reference_field
- Set field properties:
- Display name
- Required flag
- Help text (if provided)
- Validation rules (if applicable)
- Show progress: Report each field created
- Handle errors: If field creation fails, report and continue
Phase 7: Verification & Reporting
- Verify collection: Use Webflow MCP's
data_cms_toolwith actionget_collection_detailsto retrieve full schema - Confirm all fields: Check that all requested fields were created
- Generate report: Show:
- Collection ID
- Collection name and slug
- All fields created with IDs
- Any failures or warnings
- 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
sites_listto 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
→ collection_fields_create_static
Option
→ collection_fields_create_option
(requires metadata.options array)
Reference, MultiReference
→ collection_fields_create_reference
(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:

{
"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
