Zernote bypasses Claude upload limits with 2GB file support via MCP Apps

Zernote has developed a workaround to bypass Claude's file upload limits, enabling users to upload files up to 2 GB, a significant increase from the previous 500 MB cap. This solution leverages Anthropic's MCP Apps feature, which allows external applications to render as iframes within the Claude interface. By using these iframes, files are uploaded directly from the user's browser to Zernote's backend storage, bypassing Claude's context window entirely. This method is now live in Zernote's connector and is available for free trial. AI

IMPACT Enables richer data analysis within Claude by allowing larger files, potentially improving user research and other data-intensive tasks.
