What is webflow-mcp:cms-collection-setup?

A procedure for creating a Webflow CMS collection, which is a structured content type such as blog posts, products, team members, or portfolio entries.

Use it when creating a new collection with text, option, relationship, or multiple-relationship fields in Webflow.

It helps set up fields and links between content types while checking the site and existing collections first, reducing naming and configuration errors.

SkillSpector: 1 finding, up to medium

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

medium Output Handling · line 119
Output size or generation rate is not bounded. Unbounded output enables denial-of-service through resource exhaustion, log flooding, or context-window stuffing.

Fix: Set explicit limits on output length, generation count, and rate. Use max_tokens and truncation to prevent unbounded output.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00047	$0.07888
Opus 5.5	$0.00019	$0.03155
Sonnet 5.5	$0.00009	$0.01578

Security

Grade A, and why

webflow-mcp:cms-collection-setup scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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

Get site information: Use Webflow MCP's data_sites_tool with action list_sites to identify target site
Confirm site: Ask user to select site if multiple available
Check plan limits: Use Webflow MCP's data_sites_tool with action get_site to verify collection limits
List existing collections: Use Webflow MCP's data_cms_tool with action get_collection_list to 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)
