Update CMS items

Update CMS items

Updates the fields of one or more items in a CMS collection, holding changes to published items in draft until they are published.

Set up

Use the first option your agent supports.

MCP (official, remote)

Add this server to your agent's MCP settings, then sign in when asked.

{ "mcpServers": { "webflow": { "url": "https://mcp.webflow.com/mcp" } } }

Call the MCP tool data_cms_tool with PATCH /collections/{collection_id}/items.

Server URL: https://mcp.webflow.com/mcp

CLI (official)

Install the command and sign in with it, then confirm it runs.

npm install -g @webflow/webflow-cli
webflow --version

Run webflow cms items update.

API (official)

• Base URL: https://api.webflow.com/v2
• Endpoint: PATCH /collections/{collection_id}/items
• Auth: send the header Authorization: Bearer $WEBFLOW_API_TOKEN
• Docs: https://developers.webflow.com/data/reference/rest-introduction

Before anything else, confirm access with the cheapest read-only call, like a list or a search. Never send or change anything to test access.

Rules

• Ask the user before anything that sends messages, costs money, or changes data, and say how many records it touches. One approval covers a batch the user has seen.
• Never print API keys.
