Hi all - using the new Publish MCP to build a new site via Claude and loving it.. So cool! Great work to all at the Relume team.
Not sure if this has been shared elsewhere or not, but had a tip to improve Claude's ability to "see" the site that you are working on.
If you edit your Relume site through the MCP connector, Claude can read and change the structure: sections, colour schemes, tokens and copy. It can't see the page. It knows a section uses a particular scheme, but not whether the headline clashes with the image.
One setting fixes that. It lets Claude open your site from its own sandbox and take screenshots.
- 1.
In Claude, go to Settings, then Capabilities, then Code execution and file creation.
- 2.
Turn on Allow network egress. Leave the domain allowlist on "Package managers only".
- 3.
- 4.
Start a new chat and ask: "Screenshot the home page at desktop and mobile widths and tell me what you see."
Two things to know:
Claude's web fetch tool is no substitute. A draft with indexing off tells automated tools to stay out. The sandbox route is the one that works.
The MCP handles what the site is made of. This setting handles how it looks. Together, Claude can check its own work.
