# Retyc Cli > Official CLI client for Retyc with MCP server - **Type:** MCP server - **Install:** `agentstack add mcp-retyc-retyc-cli` - **Verified:** Yes — security-reviewed for prompt injection and unsafe behavior - **Seller:** [retyc](https://agentstack.voostack.com/s/retyc) - **Installs:** 0 - **Category:** [Cloud & Infrastructure](https://agentstack.voostack.com/c/cloud-infrastructure) - **Latest version:** 0.1.0 - **License:** MIT - **Upstream author:** [retyc](https://github.com/retyc) - **Source:** https://github.com/retyc/retyc-cli - **Website:** https://retyc.com ## Install ```sh agentstack add mcp-retyc-retyc-cli ``` Requires the [AgentStack CLI](https://agentstack.voostack.com/docs/cli). Works with Claude Code, Cursor, and any MCP-compatible agent. ## About # Retyc CLI > Official command-line interface for [Retyc](https://retyc.com) - 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](https://retyc.com) 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](https://github.com/retyc/retyc-cli/releases/latest). ### With `go install` ```sh go install -tags prod github.com/retyc/retyc-cli@latest ``` ### From source ```sh 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=$(git describe --tags --always)" -o retyc . ``` ### With Docker ```sh # Docker Hub docker pull retyc/retyc-cli:latest # GitHub Container Registry docker pull ghcr.io/retyc/retyc-cli:latest ``` --- ## Quick start ```sh # 1. Authenticate (opens a browser tab, no password stored) retyc auth login # 2. Send a file retyc transfer create report.pdf # 3. List your transfers retyc transfer ls # 4. Download a transfer retyc transfer download ``` --- ## Security - **Authentication**: OIDC device flow (no password ever stored locally) - **File data + metadata**: end-to-end encrypted with [AGE](https://github.com/FiloSottile/age) post-quantum hybrid keys - **Private key caching** (Linux only): the decrypted AGE identity is stored in the kernel session keyring and is never written to disk. It is scoped to the current terminal session, isolated from other users and sessions, and uses a sliding TTL (default: 60 seconds). Each access refreshes the expiration timer. - **Transport**: TLS enforced by default --- ## MCP Server `retyc-cli` runs as a [Model Context Protocol](https://modelcontextprotocol.io) server — connect it to your AI agent and control Retyc in plain language: > *"Create a dataroom called 'Release v2', upload ./dist/, and add alice@example.com as editor."* > *"Send all PDFs in ./reports/ to bob@example.com, expire in 7 days."* > *"List my latest transfers and download the most recent one into ~/Downloads/."* **Quick setup with Claude Code:** ```sh # Use read -s to avoid storing the passphrase in shell history read -rs RETYC_KEY_PASSPHRASE claude mcp add --transport stdio retyc --env RETYC_KEY_PASSPHRASE="$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)).
