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.
- Can I check a template or module file for errors before uploading it?
- 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.
For your developer
