Command-line model execution with Claude Code

The `invoke_ml_function` tool classifies text or image inputs directly from your terminal session. Claude Code runs this tool to test predictions on live logs or local files without requiring a graphical interface. You can pipe terminal outputs directly into this command to verify how your active models handle real-world server logs or user inputs in real time.

Automated pipeline management

The `list_ml_functions` tool outputs all active classifiers associated with your account. Your terminal agent uses this to map out available endpoints before running automated scripts or CI tasks. When a model is no longer needed, the agent runs `delete_ml_function` to remove the endpoint. This keeps your cloud resources clean and prevents accidental calls to deprecated models.

Terminal-based data ingestion

The `create_ml_sample` tool uploads new training data directly from your shell environment. This allows Claude Code to import local logs or scraped datasets into your training pipeline with a single terminal command. Once uploaded, the agent applies the correct tags using `annotate_ml_sample` to prepare the data for training. This lets you build and update models using cron jobs or terminal scripts.

Setup guide

Set up Nyckel ML MCP in Claude Code

Prerequisites

Claude Code CLI installed (npm install -g @anthropic-ai/claude-code)
Active Vinkius subscription with a valid endpoint token

1

Run the add command

Open your terminal and run the command shown on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com. Use --scope user to make it available across all projects.
2

Verify the connection

Start a Claude Code session and type /mcp to list connected servers. You should see nyckel-ml-mcp with a green status indicator.
3

Start using tools

Ask Claude Code something like "Check my latest Nyckel ML transactions." It will automatically discover and invoke the available Nyckel ML tools.
