Works with AI assistants

Use HubSpot: its Hubspot Advanced API lets you validate a CMS source file's contents in a single step (POST /cms/source-code/2026-09/{environment}/validate/{path}). HubSpot also has an MCP server, so an AI assistant like Claude or ChatGPT can do it for you. capabilities.work can help you get signed up and connected.

  • Is there a way to lint a CMS file against a path without saving it?
Say it to your AI assistant
  • Validate {file} as if it were saved at {path} in {environment}.
  • Check the contents intended for {path} in {environment} for errors.
