Transfa
Gives Claude the ability to upload files to transfa.sh and return shareable links without needing shell access or external infrastructure. Exposes five MCP tools: upload (with optional TTL, password, download limits), file_info (metadata and SHA-256 verification), list_uploads, delete_upload, and run_artifacts for retrieving all files associated with a pipeline run_id. Works in guest mode without an API key (10MB, 24h TTL) or authenticated with larger limits up to 100GB. Useful when Claude needs to hand off generated artifacts like reports, datasets, or model files to other agents or humans, or when you want provenance tracking across multi-step workflows. The server wraps transfa's REST API, which supports 100+ file formats including ML models, archives, and data science formats.
