Tinker CLI wrapper and bridge

Tinker CLI

A beautiful terminal interface for the Tinker API, built with Bubble Tea.

Features

• 🚀 Training Runs - View and manage your training runs
• 💾 Checkpoints - Browse, publish/unpublish, and delete model checkpoints
• 📊 Usage Statistics - View your API usage and quotas
• ⚙️ Settings - Configure API key with secure storage (OS keyring)
• ✨ Interactive UI - Beautiful dark theme with keyboard navigation
• 🔐 Secure Credential Storage - API keys stored in Windows Credential Manager / macOS Keychain / Linux Secret Service

Architecture

This CLI uses a Python bridge server to communicate with the Tinker API. The Tinker SDK uses gRPC-Web internally, so we wrap it with a FastAPI server that exposes a simple REST API for the Go CLI to consume.

┌─────────────┐      REST       ┌─────────────────┐     gRPC-Web    ┌─────────────┐

Installation

Prerequisites

• Go 1.21 or later
• Python 3.8 or later
• A Tinker API key

Build from source

git clone https://github.com/mohadese/tinker-cli.git
cd tinker-cli
go build -o tinker-cli .

Install Python dependencies

cd bridge
pip install -r requirements.txt

Configuration

Option 1: Use the Settings Menu (Recommended)

The easiest way to configure your API key is through the CLI itself:

1. Run ./tinker-cli
2. Select Settings from the menu
3. Select API Key and enter your key
4. The key will be stored securely in your OS keyring:
   • Windows: Credential Manager
   • macOS: Keychain
   • Linux: Secret Service (GNOME Keyring, KWallet, etc.)

Option 2: Environment Variable

Alternatively, set your Tinker API key as an environment variable:

# Linux/macOS
export TINKER_API_KEY="your-api-key-here"

# Windows (PowerShell)
$env:TINKER_API_KEY="your-api-key-here"

# Windows (CMD)
set TINKER_API_KEY=your-api-key-here

Note: Environment variables take precedence over stored credentials.

Usage

Step 1: Start the Bridge Server

First, start the Python bridge server in one terminal:

# Windows (PowerShell)
.\bridge\start_bridge.ps1

# Windows (CMD)
bridge\start_bridge.bat

# Linux/macOS
cd bridge && python server.py

# Or manually:
cd bridge
pip install -r requirements.txt
python server.py

The bridge server will start on http://127.0.0.1:8765 by default.

Step 2: Run the CLI

In another terminal, run the CLI:

./tinker-cli

Environment Variables

Troubleshooting

"Bridge server not running" error

Make sure the Python bridge server is running before starting the CLI:

cd bridge
python server.py

"TINKER_API_KEY not set" error

Set your API key in the environment:

export TINKER_API_KEY="your-api-key-here"

"tinker SDK not installed" error

Install the Tinker SDK:

pip install tinker
