Official command-line interface for Retyc - send transfers and manage datarooms directly from your terminal. Also runs as a local MCP server: connect your AI agent and control Retyc in plain language.
Retyc is a European sovereign file-sharing platform with end-to-end post-quantum encryption. Data stays in Europe, GDPR-compliant by design.
retyc-cli lets you integrate Retyc transfers and datarooms into your scripts, pipelines, and workflows - no browser
required.
Download the binary for your platform from the latest release.

- File data + metadata: end-to-end encrypted with AGE post-quantum hybrid keys
- Private key caching (Linux only): the decrypted AGE identity is stored in the kernel session keyring and is never written to disk. It is scoped to the current terminal session, isolated from other users and sessions, and uses a sliding TTL (default: 60 seconds). Each access refreshes the expiration timer.
- Transport: TLS enforced by default
retyc-cli runs as a Model Context Protocol server — connect it to your AI agent and
control Retyc in plain language:
"Create a dataroom called 'Release v2', upload ./dist/, and add alice@example.com as editor." "Send all PDFs in ./reports/ to bob@example.com, expire in 7 days." "List my latest transfers and download the most recent one into ~/Downloads/."
Quick setup with Claude Code:
# Use read -s to avoid storing the passphrase in shell history
read -rs RETYC_KEY_PASSPHRASE
claude mcp add --transport stdio retyc --env RETYC_KEY_PASSPHRASE="$RETYC_KEY_PASSPHRASE" -- /path/to/retyc mcp serveFull integration guide (Claude Desktop, Cursor, Windsurf, example prompts): doc/mcp.md
