# SAFE MCP Server

An [MCP](https://modelcontextprotocol.io/) server that gives AI assistants the ability to encrypt and decrypt files using SAFE.

## Prerequisites

The `safe` CLI must be installed and available in PATH. See [thesafe.dev/download](https://thesafe.dev/download).

## Setup

### Claude Desktop

Add to `~/Library/Application Support/Claude/claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "safe-encryption": {
      "command": "npx",
      "args": ["safe-mcp-server"]
    }
  }
}
```

### Cursor

Add to `.cursor/mcp.json`:

```json
{
  "mcpServers": {
    "safe-encryption": {
      "command": "npx",
      "args": ["safe-mcp-server"]
    }
  }
}
```

## Available Tools

| Tool | Description |
|------|-------------|
| `safe_encrypt` | Encrypt text or file with password, public key, or GitHub username |
| `safe_decrypt` | Decrypt a .safe file (auto-discovers keys from ~/.safe/ and ~/.ssh/) |
| `safe_keygen` | Generate encryption keypair (x25519, p-256, ml-kem-768) |
| `safe_info` | Inspect encrypted file metadata without decrypting |
| `safe_keys` | List identities and recipients |

## Usage

Once configured, ask your AI assistant:

- "Encrypt this file with a password"
- "Decrypt secrets.safe"
- "Generate an encryption key"
- "Encrypt this for github:alice"
- "Who can decrypt this .safe file?"
