What is webflow-mcp:cms-best-practices?

Guidance for designing and troubleshooting Webflow CMS structures. Webflow is a visual website builder, and a CMS stores structured content such as articles or products.

Use it when planning collections, examining existing schemas and items, choosing relationships, optimizing content structure, or investigating CMS problems.

It helps reason about collections, fields, relationships, pages, and content volume before changing a site's content model.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add webflow/webflow-skills --skill cms-best-practices

Clone the repo

git clone --depth 1 https://github.com/webflow/webflow-skills

Made for: Cursor.

Or install webflow, the plugin that ships this one along with the rest of its 33 skills, 1 agent.

SkillSpector: 1 finding, up to high

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 →

high Rogue Agent · line 678
Skill modifies its own code, configuration, or behavior at runtime. Self-modification enables an agent to escalate privileges, disable safety constraints, or install persistent backdoors.

Fix: Prevent the skill from modifying its own code, SKILL.md, or configuration files. Treat skill files as read-only at runtime.

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	$0.00040	$0.13387
Opus 5.5	$0.00016	$0.05355
Sonnet 5.5	$0.00008	$0.02677
Haiku 4.5	$0.00004	$0.01339

Security

Grade A, and why

webflow-mcp:cms-best-practices 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 Best Practices

Provide expert guidance on Webflow CMS architecture, relationships, optimization, and troubleshooting.

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 analyze existing collections
Use Webflow MCP's data_cms_tool with action get_collection_details to examine collection schemas
Use Webflow MCP's data_cms_tool with action list_collection_items to assess content volume
Use Webflow MCP's data_pages_tool with action list_pages to understand page structure
Use Webflow MCP's ask_webflow_ai for specific API questions
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: Discovery & Analysis

Identify the request: Determine if user is:
- Planning new CMS structure
- Optimizing existing collections
- Troubleshooting performance issues
- Setting up relationships
- Seeking architecture guidance
Get site information: Use Webflow MCP's data_sites_tool with actions list_sites and get_site to understand plan limits
Analyze existing structure: Use Webflow MCP's data_cms_tool with actions get_collection_list and get_collection_details to examine current setup
Assess content volume: Use Webflow MCP's data_cms_tool with action list_collection_items to understand scale
Review pages: Use Webflow MCP's data_pages_tool with action list_pages to see how content is displayed

Phase 2: Requirements Gathering

Understand use case: Ask clarifying questions:
- What content needs to be managed?
- Who will update the content?
- How will content be displayed?
- What relationships are needed?
- Expected content volume?
Identify constraints: Consider plan limits, technical constraints, team skills
Define success criteria: Performance goals, editorial workflow, scalability needs
