Generate SSH keys for Hetzner Cloud server authentication. Add a name and public key to create secure access credentials.
Instructions
Create a new SSH key.
Creates a new SSH key with the specified name and public key data.
Examples:
- Basic SSH key: {"name": "my-ssh-key", "public_key": "ssh-rsa AAAAB3NzaC1..."}
- With labels: {"name": "user-key", "public_key": "ssh-rsa AAAAB3NzaC1...", "labels": {"environment": "production"}}Input Schema

Implementation Reference
- mcp_hetzner/server.py:1239-1259 (handler)The handler function decorated with @mcp.tool() that implements the create_ssh_key tool. It uses the Hetzner client to create an SSH key with the given name, public_key, and optional labels, then serializes and returns it or an error.
