Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.

Preview Execution monitoring

We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

About

Retyc CLI

> Official command-line interface for Retyc - send transfers and manage datarooms directly from > your terminal. Also runs as a local [MCP server](doc/mcp.md): connect your AI agent and control Retyc in plain > language.

What is Retyc?

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.

Installation

Pre-compiled binaries (recommended)

Download the binary for your platform from the latest release.

With `go install`

go install -tags prod github.com/retyc/retyc-cli@latest

From source

git clone https://github.com/retyc/retyc-cli.git
cd retyc-cli
go build -tags prod -ldflags "-X github.com/retyc/retyc-cli/cmd.Version=$(git describe --tags --always)" -o retyc .

With Docker

# Docker Hub
docker pull retyc/retyc-cli:latest
# GitHub Container Registry
docker pull ghcr.io/retyc/retyc-cli:latest

Quick start

# 1. Authenticate (opens a browser tab, no password stored)
retyc auth login

# 2. Send a file
retyc transfer create report.pdf

# 3. List your transfers
retyc transfer ls

# 4. Download a transfer
retyc transfer download

Security

Authentication: OIDC device flow (no password ever stored locally)
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

MCP Server

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 serve

Full integration guide (Claude Desktop, Cursor, Windsurf, example prompts): [doc/mcp.md](doc/mcp.md)

Claude Desktop extension (MCPB): each release ships a retyc-.mcpb bundle — double-click to install in Claude Desktop, no terminal needed. See [doc/mcpb.md](doc/mcpb.md).

Privacy Policy

This software (CLI and MCP server) embeds the entire encryption layer: file contents and metadata are encrypted locally (post-quantum AGE) before transmission, and its only network endpoint is the Retyc API — Retyc servers never see plaintext. In MCP mode, tool responses return decrypted metadata (filenames, sizes, member lists) to your MCP client; file contents are never included in responses (see [SECURITY.md](SECURITY.md)).
