File Store MCP

What it does

File Store MCP is a versatile storage bridge that allows AI agents to upload local files, clipboard content, or remote URLs to various cloud storage providers. It transforms local data into accessible HTTP URLs, enabling LLMs to reference files, images, and documents in a cloud-native way.

Tools

• upload_files: Uploads absolute local file paths to cloud storage and returns HTTP URLs.
• upload_clipboard_files: Transfers files currently in the system clipboard to the cloud.
• upload_url_files: Downloads files from a remote URL and re-uploads them to the configured cloud provider.

go install github.com/sjzar/file-store-mcp@latest
