teasel 0.3.0

Connect lab instruments to AI assistants

teasel

Connect lab instruments to AI assistants.

teasel is a CLI and TUI for configuring which instruments are available to your AI assistant. It browses the community instrument registry, prompts for connection details, and writes a .mcp.json file that Claude Code (or any MCP-compatible assistant) picks up automatically.

Quick start

uvx teasel

This opens the interactive TUI. Browse instruments, select one, enter your connection details, and the config is written.

CLI commands

# Add an instrument (prompts for required config)
uvx teasel add lecroy-wavesurfer

# Add with config inline
uvx teasel add lecroy-wavesurfer --set LECROY_HOST=192.168.1.111

# List configured instruments
uvx teasel list

# Remove an instrument
uvx teasel remove lecroy-wavesurfer

# Regenerate .mcp.json from saved state
uvx teasel apply

What it generates

teasel writes a .mcp.json in the current directory:

{
  "mcpServers": {
    "lab": {
      "command": "uvx",
      "args": ["teasel-server"],
      "env": {
        "LECROY_HOST": "192.168.1.111",
        "PM5190_PORT": "/dev/ttyUSB0"
      }
    }
  }
}

Claude Code reads this file and starts teasel-server automatically. You only need to run teasel once per project, or whenever your instrument setup changes.

Instrument state

Configured instruments are saved to ~/.config/teasel/instruments.toml. Running teasel apply in any directory regenerates .mcp.json from this state.
